8. Tóm tắt nội dung: Will community monitoring assist in delivering just and equitable REDD+? We assessed whether local communities can effectively estimate carbon stocks in some of the world’s most carbon rich forests, using simple field protocols, and we reviewed whether community monitoring exists in current REDD+ pilots. We obtained similar results for forest carbon when measured by communities and professional foresters in 289 vegetation plots in Southeast Asia. Most REDD+ monitoring schemes, however, contain no community involvement. To close the gulf between United Nations Framework Convention on Climate Change texts on involving communities and field implementation realities, we propose greater embedding of community monitoring within national REDD+ pilot schemes, which we argue will lead to a more just REDD+.

8. Tóm tắt nội dung: Increasing industrialization in Vietnam has transformed numerous fields of farmers to industrial zones, especially in the Red River Delta in Vietnam. This process forces farmers to change significantly their livelihoods. Affected same changes, farmers have to start new livelihoods. However, in many industrializing regions, inequality and social differentiation are increasing higher than before among farmers practicing new livelihoods. This implies that new livelihoods of partly farmer groups are not as good as those of others. Such farmer groups have faced difficulties preventing them to have better livelihoods, and creating hidden social stratification. From perspective of human development as capabilities expansion, this research identifies difficulties and farmers’ capabilities during the process of starting new livelihood. As preliminary results, there are farmer groups having limited choices for new good livelihoods. Main difficulties in transition livelihoods are lack of financial resources, new working skills, market information, market linkages, and constraint of age. Such problems create deprivation of capability or freedom in starting new good livelihood. Of methodology, the research examines changes in livelihoods of farmers who are affected from agricultural land conversion for industrialized zones in Red River Delta, Vietnam. In-depth interview and group discussion are taken to understand transition in livelihoods, and farmers ‘capabilities in starting new livelihoods. This research contributes to human development discourse from aspect of livelihoods. Also, identifying difficulties is useful for explaining inequality and social differentiation under industrialization. The research is helpful for policy makers and state staffs who design and implement policies of agriculture and industrialization.

8. Tóm tắt nội dung: Low awareness on sustainable production and farming techniques are major factors limiting cassava (Manihot esculenta Crantz) production in the northern mountainous region of Vietnam. In 2011, three experiments were conducted in Van Yen District of Yen Bai province, Vietnam, to determine the appropriate plant density (a control at 10,000 plants.ha-1, high stocking at 12,500 plants.ha-1 and extra-high stocking at 14,000 plants.ha-1), the proper NPK+S fertilizer level (low at 800 kg.ha-1, a control at 1,000 kg.ha-1, a high level at 1,200 kg.ha-1 and an extra-high level at 1,400 kg.ha-1), as well as incorporating the study of a suitable cassava intercropping system for controlling soil erosion. The high density and high fertilizer levels signifi cantly increased the fresh root yield, harvest index, root dry matter and starch content compared to those of the control. However, these parameters were not different at both the extra-high density and extra-high fertilizer levels from those of the high density and high fertilizer levels. In addition, there were no signifi cant differences in the sprouting percentage, the stem diameter with increased stocking and the fertilizer level. It was found that cassava intercropped with peanut, using Tephrosia candida hedgerows, not only considerably increased the plant height, fresh root yield, harvest index, root dry matter and starch content, but also effectively decreased the dry soil loss compared to mono-cropping.

8. Tóm tắt nội dung: Aster spathulifolius Maxim là một loài phân bố hẹp và đặc hữu xuất hiện ở các vùng ven biển của Hàn Quốc và Nhật Bản. Sự đa dạng di truyền và sự khác biệt của mười lăm quần thể của các loài đã được phân tích trong tám locus bằng cách sử dụng sáu đoạn mồi lặp lại liên tục đơn giản. Tổng số đa dạng di truyền ở cấp loài rất cao (P = 98,78%, Hsp = 0,33 ± 0,444, I = 0,501 ± 0,1880), trong khi đa dạng di truyền ở mức độ dân cư tương đối thấp (P = 43,74%, Hpop = 0,50 ± 0,189, I = 0,27 ± 0,274). Sự phân hóa di truyền cao giữa các quần thể được phát hiện dựa trên hệ số phân hóa di truyền (Gst = 0.549) và phân tích phương sai phân tử (AP = 54.06%). Những phát hiện này cùng với ước tính lưu lượng gen thấp (Nm = 0,205) cho thấy rằng sự di truyền của sự cô lập là yếu tố quan trọng nhất để thiết lập cấu trúc di truyền hiện tại của loài. Sự suy giảm về sự phong phú của A. spathulifolius cùng với mức độ đa dạng di truyền thấp chỉ ra rằng các chiến lược bảo tồn là cần thiết.

8. Tóm tắt nội dung: The present study investigates the hypothesis that arsenic concentrations correlate with tubewell depth, and examines the effectiveness of spline interpolation, specifically completely regularized spline (CRS) and spline with tension (SWT) in estimating the magnitude of arsenic contamination in groundwater in Thanh Tri, a densely populated district located in the southern part of Hanoi City, Vietnam. Groundwater sampling conducted in 72 tubewells drilled into shallow aquifers yielded an average arsenic concentration of 82 μg/L with a maximum of 395 μg/L, far higher than the World Health Organization (WHO) guideline value of 10 μg/L. The average concentration in the lower Pleistocene aquifer was 86 μg/L, slightly higher compared with the average of 78 μg/L in the upper Holocene aquifer. Interestingly, regression analysis revealed that in the Holocene aquifer, depth of wells influenced arsenic concentrations significantly. Such an influence, however, was insignificant in

the lower Pleistocene aquifer. Both the CRS and SWT spatial interpolation models resulted in plausible predictions for the arsenic concentration data. The problem of arsenic contamination in the study area should be considered seriously, as 99% of the area was estimated to be affected by arsenic levels exceeding the WHO guideline value.

8. Tóm tắt nội dung: This study demonstrated the prevalence of Porcine circovirus type 2 (PCV2) among pig farms in Vietnam. Analyses of the genome, capsid protein and phylogeny classified all 30 Vietnamese PCV2 strains as the PCV2b genotype, belonging to the clusters of 1A, 1B, 1C and recombinant forms. Each viral genome was 1767 nucleotides long and shared 96.0-100% nucleotide sequence identity. The amino acid substitutions in the capsid protein of the Vietnamese PCV2 strains were in immunodominant regions, and the majority of strains (24/30) contained a lysine extension at the C-terminus. Bayesian phylogeographic analysis revealed epidemic links of the PCV2 recombinant cluster within and among countries, which supports a circulating recombinant form of PCV2. Further analysis by the Jameson-Wolf antigenic index indicated antigenic alterations at important sites in the capsid protein (sites 131-133) among the recombinant cluster and the other clusters of PCV2b.

8. Tóm tắt nội dung: Vietnam is facing serious challenges with respect to the amount and toxicity of the pesticides used. With hardly any domestic pesticides production, Vietnam experienced an exponential growth of both the quantity and the value of imported pesticides in recent years. And the increasing import of newly formulated (and safer) pesticides has not replaced or reduced the highly toxic pesticides with low efficacy. The improper use of pesticides by farmers (too high dosages, cocktailing of pesticides, inadequate pre-harvest intervals etc.) has further contributed to the environmental and health problems resulting from pesticides, especially in poorer areas. Despite a growth in pesticide policies and regulation, the state has been unable to regulate the pesticide market. The main causes behind the state failure in pesticide market regulation are the governance structure, large corruption, information distortion and a failing legal system. To some extent, and in some more wealthy areas, famers and retailers have emerged successfully as new pesticide governance actors. But an overall improvement of pesticide registration and pesticide use can only rely on better government intervention: more stringent implementation and enforcement of regulations, more effective promotion of IPM-based pest control, further public participation in implementation and higher ethics within government.

8. Tóm tắt nội dung: Understanding the spatial and temporal variations in toposequential methane (CH4) emission is essential for assessing and mitigating CH4 emission from rice cascades in mountainous watersheds. To assess the toposequential variation in CH4 emission among different field positions, two cascades of double cropping paddy rice fields were investigated in Yen Chau district, Northwest Vietnam. The cascades were divided into fertilized and non-fertilized parts and CH4 measurements at 10 days intervals were conducted at top, middle and bottom fields of each part. The results showed that the rate and cumulative amount of CH4 emissions in non-fertilized part were higher than that of fertilized one in both spring and summer rice seasons due to the stimulation of CH4 oxidation by urea and sulfate containing fertilizers. The spatial variation in CH4 emissions among the field positions was high in both cropping seasons with the highest emissions in the bottom fields and the lowest emissions were found in the top fields (i.e. bottom field CH4 emissions 1.8–3.0 times higher than the top field). The differences among field positions were influenced by clay content, total nitrogen and total carbon content which showed toposequential differences. The average CH4 fluxes ranged from 1.0 to 5.1 mg CH4 m−2 h−1 being largest at later growth stages for spring rice and during early growth stages for summer rice. Cumulative CH4 emissions for spring rice ranged from 3.1 to 13.7 g CH4 m−2 and that for summer rice from 4.3 to 23.5 g CH4 m−2. 61.7% was emitted during summer rice season and 38.1% from spring rice season. The higher values for summer crops were due to higher availability of fresh organic substrates under higher soil temperature during the early growing period. The average total CH4 emissions from double-cropping paddy rice fields were 14.8 g CH4 m−2 for cascade 1 and 27.3 g CH4 m−2 for cascade 2. The higher emission for cascade 2might be due to the lower soil Eh and higher clay content especially in the lower lying fields. The results highlight that large toposequence differences in CH4 emissions require different site specific management practices for each toposequence position in order to mitigate CH4 emission in paddies in mountainous watersheds.

8. Tóm tắt nội dung: To  characterize   the   annual  and   spatial  variation  in   grain  yield  of   deepwater  rice   on  the   floodplains  of

Tonle   Sap   Lake,  Cambodia,  from  2008  to   2011  we  collected  information   on  water  availability,   farming

practices,  and   rice   yield  through   intensive   field  monitoring,  farmer  interviews  and   yield  sampling  along

a  transect   line   of   a  water  depth   gradient.  A  total  of   86  fields  covering  91.5  ha  were  divided  into   3  zones: an  upper   zone  where  only  lowland   rice   (LR)   was   grown  (referred  to   as  ULR),  a  middle  zone  where  both  LR and   floating   rice   (FR)   were  grown  (MLR   and   MFR,  respectively),  and   a  lower   zone  closest  to   the   lake   where only  FR  was   grown  (LFR).   The   inundation  from  Tonle   Sap   Lake  was   within  the   normal  range   in   2008  and 2009,   but   it   was   extremely   large   and   caused  a  complete  crop  failure  in   the   study   area  in   2011.   Conversely, no  inundation  occurred  in   2010.   Continuous  standing  of   water  started  earlier  (i.e.,   early  September)   in the   lower   zone  and   reached   maximum  depth   in   mid-October;  water  receded   earlier  (i.e.,   mid-  to   late November)  in   the   upper   zone  than  in   the   lower   zone.   FR  was  broadcast   earlier  (April)  and   harvested   later (January)   than  LR  (May   and   late   November  to   December,  respectively).  A  total  of   6  LR  varieties  and   4  FR varieties  with  different  heading   times   were  planted   during  the   study   period.  Maximum  and   average   yields of   LR  were  higher  than  those   of   FR,  and   from  2008  to   2011  the   proportion  of   the   LR  variety  Raing   Chey planted   steadily   increased,   whereas  that   of   the   late-maturing   floating   rice   variety  Veal  Veng  decreased. Grain yield  in   the   middle  zone  was   the   lowest  of   the   three   zones.   Maintenance  of   standing  water  after heading, larger   input   of   N  fertilizer,   and   appropriate   weed  management  were  found   to   contribute  to higher  yields   for  both  LR  and   FR.  These   results  should  help  farmers   to   cope  with  unpredictable   flooding in   areas  where  deepwater  rice   is   cultivated.

8. Tóm tắt nội dung: In this paper, we introduce a new approach based on DC (Difference of Convex functions) Programming and DCA (DC Algorithm) for minimizing the maintenance cost involving flow-time and tardiness penalties by optimal scheduling and real-time assignment of preventive maintenance jobs on parallel processors. The main idea is to divide the horizon considered into H intervals. The problem is first formulated as a mixed integer linear problem (MILP) and then reformulated as a DC program. A solution method based on DCA is used to solve the resulting problem. The efficiency of DCA is compared with the algorithm based on the new flow-time and tardiness rule (FTR) given in [1]. The computational results on several test problems show that the solutions provided by DCA are better

8. Tóm tắt nội dung: In recent years, pig breeding has developed very fast in Hungyen Province, located in the Red River Delta of Vietnam adjacent to the capital of Hanoi. The following four pig-farming systems are performed there: 1) VAC system: a combination of fruit cultivation, fish culture with pig farming; 2) AC system: a combination of fish culture with pig farming; 3) VC system: a combination of fruit cultivation with pig farming; and 4) C system: only pig farming, respectively. Among these systems, VAC system had the highest occupancy (45.6%), followed by AC system (23.3%) and then by C system (21.5%), and VC system had the lowest occupancy (9.6%) in number in the investigated two districts of the province. The level of the pollution of the surface and groundwater was monitored for the four systems. The monitoring was done six times with a two-month interval during February to December in 2010. As the result, the surface water was evaluated to be strongly polluted in each pig-farming system, i.e. the chemical oxygen demand (COD), biological oxygen demand (BOD), and ammonium-N and phosphate-P concentrations on average exceeded the national technical regulation standard, and the dissolved oxygen (DO) on average was very low. For the groundwater, the average ammonium-N concentration exceeded the standard in each pig-farming system. However, the level of the surface and groundwater pollution was not similar among the pig-farming systems. In general, the level of surface and groundwater pollution was high in C and VC systems, intermediate in VAC system and low in AC system, respectively.

8. Tóm tắt nội dung: In Japan, each municipality generally has its own municipal solid waste incineration facilities because of the principle of self-management in the respective territories. Typically, a small municipality often owns a small facility. However, a large facility

which can run continuously at high temperature with stability would be preferable if the dioxin generation mechanism is to be considered. Accordingly, municipalities in contiguous areas should cooperate mutually by using a large facility.To evaluate the effect of the concentration of large facilities, the authors created a Geographic Information System based database of combustible waste generation at town level in Shizuoka Prefecture. Focusing on large facilities in Shizuoka City and superannuated facilities in Shida area, the authors evaluated the effect of the concentration of large facilities in Shizuoka city on utilization rate of facilities, energy balance and CO2 emissions.Our results showed the amount of light oil consumption and CO2 emissions increased because the mileage distance of garbage collection trucks becomes longer. However, the utilization rates of facilities and the amount of energy

recovery from waste are improved. From these standpoints, the authors conclude that the concentration of large facilities is better compared to a single municipality based facility

8. Tóm tắt nội dung: Most Alternaria spp. are considered asexual but recent molecular evolution analyses of Alternaria mating-type genes show that the mating locus is under strong purifying selection, indicating a possible role in sexual reproduction. The objective of this study was to determine the mode of reproduction of an Alternaria alternata sensu lato population causing citrus brown spot in central Florida. Mating type of each isolate was determined, and isolates were sequenced at six putatively unlinked loci. Three genetically distinct subpopulations (SH1, SH4A, and SH4B) were identified using network and Bayesian population structure analyses. Results demonstrate that most subpopulations of A. alternata associated with citrus are clonal but some have the ability to extensively recombine through a cryptic sexual cycle or parasexual cycle. Although isolates were sampled in close physical proximity (≈2,500-m² area), we were able to reject a random mating model using multilocus gametic disequilibrium tests for two subpopulations, SH1 and SH4B, suggesting that these subpopulations were predominantly asexual. However, three recombination events were identified in SH1 and SH4B and localized to individuals of opposite mating type, possibly indicating meiotic recombination. In contrast, in the third subpopulation (SH4A), where only one mating type was present, extensive reticulation was evident in network analyses, and multilocus gametic disequilibrium tests were consistent with recombination. Recombination among isolates of the same mating type suggests that a nonmeiotic mechanism of recombination such as the parasexual cycle may be operating in this subpopulation. The level of gene flow detected among subpopulations does not appear to be sufficient to prevent differentiation, and perhaps future speciation, of these A. alternata subpopulations.

8. Tóm tắt nội dung: Continuous experiments for phosphate removal and recovery from a synthetic wastewater containing calcium phosphate were carried out using an electrolytic reactor equipped with a multi-electrode system. Experimental results demonstrated that phosphate was removed by deposition of aggregates in reactor. In addition, it was found that removal rates and recovery rates of phosphate increased and, after reaching their maximum values, decreased with an increment of applied electric current. Deposit in reactor was recovered and was identified as hydroxyapatite (HAP) from XRD analysis. Furthermore, from comparisons of observed and calculated ions fluxes, it was shown that removal rates of phosphate had a maximum value at a certain electric current density and were controlled by either electrolytic production of hydroxyl ion or mass transfer of hydrogen phosphate ion depending on applied electric current density. Moreover, it was considered that the removal and recovery performance could be enhanced by using working electrodes having larger specific surface area.

8. Tóm tắt nội dung: Irrigation is the key to social and economic development. Reforms in water governance are slowly taking place due to the lack of administrative capacity and interests for actors to change. This descriptive research on water governance focused on the assessment of the leadership and the type of leadership style and the participation of the members. Methods used include household interview, key informant interview, focus group discussion, review of documents, and observation. Stratified sampling was utilized wherein the respondents were randomly selected. Data were described using descriptive statistics such as frequency distribution and percentages. Results revealed that members of the irrigators’ association have the liberty to express and that leader and members decide on what is best. They are

partners in the various phases of activities. Officers consult the members. And the members participate in various activities. Both IA members and officers are involved in the planning and implementation phases. In the governance of irrigation water, officers practice a democratic leadership style. This is evident in the following: consultation among members in making decisions, delegation of power, openness, and encouragement for participation. Good leadership among the Irrigator’s Association encouraged the members to actively participate in the planning and implementation of the irrigation system. The democratic leadership style of the irrigators’ association has been proven effective in the management of the irrigation system in order to have good water governance. The participation of the members (81.82%) is associated to their high level of awareness that the operation and maintenance of the irrigation system is their responsibility to have equitable water distribution.

Key Words: Participation, leadership, water governance

8. Tóm tắt nội dung: Farm irrigation has the highest total water consumption. This study on water governance for irrigation delved into water allocation and water usage in Sta. Cruz River Watershed, Laguna, Philippines. Methods used for data gathering were household interview, key informant interview, focus group discussion, review of documents, and observation. Results reveal that water is always available for farm irrigation. Immediate repair of damaged irrigation canal was a recommendation identified to reduce water wastage. Farmers are aware that water is an economic good and that rice production will be affected when there is limited water supply. Such awareness leads to the proper use of water. Water distribution by schedule was identified as a measure to control water. There are non-rice farmers having free access to the irrigation water resulting in a competition for water use among farmers. The paper recommends the maintenance of irrigation canals and the involvement of the Department of Environment and Natural Resources for the rehabilitation of the watershed.

8. Tóm tắt nội dung: This paper described the apparatus for biological pre-treatment of petrochemical wastewater that is collected from styrene and propylene oxide production. The values of organic contaminants loading and the pH of the incoming wastewater to the bioreactor are determined. The dependence of the foaming on various physico-chemical and biological parameters of pre-treatment apparatus is analyzed to manage investigated process. It is shown that the foaming process increases with increasing pH of wastewater and content of wastewater contamination. Thus, shift of the pH value into an alkaline region and increase of the wastewater organic loading in 10% resulted in 3-5 multiple foaming increasing. The amount of microbial biomass in the bioreactor generally has the most critical influence on the foaming and cleaning efficiency of wastewater. At neutral pH changes in the range of biomass (OD590) from 0.03 to 0.12 resulted in a slight increase in foam, whereas a further increase of the microbial biomass in the studied bioreactor waste water led to a sharp increase in foaming.

8. Tóm tắt nội dung: This article presented a system of petrochemical wastewater pre-treatment of propylene oxide and styrene production in the bioreactor that allows reducing the toxic load of the effluents on activated sludge, realizing subsequent treatment of wastewater in the aerotanks. The wastewater that enters to the bioreactor contains along with styrene and propylene oxide, acetophenone, methylphenylcarbinol, benzene, phenol, mono- and dipropylene glycol, propanol and ethanol, etc. We tested different immobilized carriers to increase the biotreatment process efficiency. We revealed that the most effective immobilized material was fiberglass ruff in comparison with activated carbon and polyurethane. The installation parameters are analyzed and the cleaning efficiency of each carrier is defined. Using a carrier in the form of fiberglass ruff allows increasing removal efficiency of organic compounds up to 96%.

8. Tóm tắt nội dung: Domain decomposition methods were first developed for elliptic problems, taking advantage of the strong regularity of their solutions. In the last two decades, many investigations have been devoted to improve the performance of these methods for elliptic and parabolic problems. The situation is less clear for hyperbolic problems with possible singular solutions. In this paper, we will discuss a nonoverlapping domain decomposition method for nonlinear hyperbolic problems. We use the finite volume method and an implicit version of the Roe approximate Riemann solver, and propose a new interface variable inspired by Dolean and Lanteri [1]. The new variable makes the Schur complement approach simpler and allows the treatment of diffusion terms. Numerical results for the compressible Navier-Stokes equations in various 2D and 3D configurations such as the Sod shock tube problem or the lid driven cavity problem show that our method is robust and efficient. Comparisons of performances on parallel computers with up to 512 processors are also reported.

8. Tóm tắt nội dung: Most Alternaria spp. are considered asexual but recent molecular evolution analyses of Alternaria mating-type genes show that the mating locus is under strong purifying selection, indicating a possible role in sexual reproduction. The objective of this study was to determine the mode of reproduction of an Alternaria alternata sensu lato population causing citrus brown spot in central Florida. Mating type of each isolate was determined, and isolates were sequenced at six putatively unlinked loci. Three genetically distinct subpopulations (SH1, SH4A, and SH4B) were identified using network and Bayesian population structure analyses. Results demonstrate that most subpopulations of A. alternata associated with citrus are clonal but some have the ability to extensively recombine through a cryptic sexual cycle or parasexual cycle. Although isolates were sampled in close physical proximity (≈2,500-m2 area), we were able to reject a random mating model using multilocus gametic disequilibrium tests for two subpopulations, SH1 and SH4B, suggesting that these subpopulations were predominantly asexual. However, three recombination events were identified in SH1 and SH4B and localized to individuals of opposite mating type, possibly indicating meiotic recombination. In contrast, in the third subpopulation (SH4A), where only one mating type was present, extensive reticulation was evident in network analyses, and multilocus gametic disequilibrium tests were consistent with recombination. Recombination among isolates of the same mating type suggests that a nonmeiotic mechanism of recombination such as the parasexual cycle may be operating in this subpopulation. The level of gene flow detected among subpopulations does not appear to be sufficient to prevent differentiation, and perhaps future speciation, of these A. alternata subpopulations.

8. Tóm tắt nội dung: T 2-Sulfanyl-3-methylbutyl formate and acetate were synthesized without purification steps, quantified with a pulsed flame photometric equimolar detector, and characterized by comparison with commercially available 3-sulfanyl-3-methylbutyl formate and acetate (retention indexes, mass spectra, odour descriptors, and intensities). Both formates exhibited a typical ribes flavour, in contrast to both acetates, which were much more piquant. The sensorial threshold of 3-sulfanyl-3-methylbutyl formate was much lower (57 ng/l in beer, BE-GC-LoADS=0.0006 ng) than those measured for the three other esters. Only 3-sulfanyl-3-methylbutyl formate was perceived at the sniffing port in beer extracts. Concentrations up to 1230 ng/l were measured in pilot beers after 1 month at 20 _x00E_C, although the compounds are rarely detected in commercial beers with highly oxygen-protected bot-tling. Accelerated ageing in the presence of oxygen confirmed the key role of oxygen.

8. Tóm tắt nội dung: Polyfunctional thiols are contributors to the hop varietal aroma of beer. Besides free thiols, a cysteine-S-conjugate has recently been shown to be an additional component of the thiol potential of hop. Such cysteine adducts investigated here in four hop cultivars and in different hop forms. Hop hydroalcoholic extracts were purified on a cation exchanger and subjected to apotryptophanase β-lyase activity. The Cascade hop variety exhibited the highest bound 3-sulphanylhexan-1-ol (grapefruit-like) potential, while both Tomahawk and Nelson Sauvin cultivars were confirmed to be important sources of bound 3-methyl-2-butene-1-thiol (skunky-like), 3-sulphanylpentan-1-ol and 4-sulphanyl-4-methylpentan-2-one (box-tree-like). Surprisingly, hop CO2 extracts proved to contain cysteine conjugates. Although related, the concentrations of cysteine-bound thiols in hop are not strictly correlated to the amounts of free volatiles found in the derived beers.

8. Tóm tắt nội dung: Depuis deux décennies, la recherche en œnologie s’intéresse aux thiols polyfonctionnels, composés clés de l’arôme variétal de vins issus de certains cépages. Les adduits S-conjugués à la cystéine et au glutathion du raisin sont désignés comme précurseurs prépondérants des thiols générés au cours de la fermentation (activité beta-lyase de la levure). En brasserie, l’intérêt pour ces composés ne fait que croître en raison de la récente mise en évidence d’une présence abondante d’adduits S-cystéinés dans le houblon. Afin de mieux cerner l’intérêt de différents adduits pour l’industrie brassicole, l’étude bibliographique présentée dans cet article fait le point sur les données actuellement disponibles quant à leurs voies de synthèse et de dégradation dans la vigne et le vin.

8. Tóm tắt nội dung: A species diversity study of lactic acid bacteria occurring in traditional Vietnamese nem chua yielded an isolate, LMG 26767T, that could not be assigned to a species with a validly published name. The isolate was initially investigated by 16S rRNA gene sequence analysis, which revealed

that it belonged to the genus Lactobacillus, with Lactobacillus manihotivorans and Lactobacillus camelliae as the closest relatives (98.9% and 96.9% gene sequence similarity to the type strains, respectively). Comparative (GTG)5-PCR genomic fingerprinting confirmed the unique taxonomic status of the novel strain. DNA–DNA hybridization experiments, DNA G+C content determination, sequence analysis of the phenylalanyl-tRNA synthase (pheS) gene, and physiological and biochemical characterization demonstrated that strain LMG 26767T represents

a novel species, for which the name Lactobacillus porcinae sp. nov. is proposed; the type strain is LMG 26767T (5CCUG 62266T). Biochemically, L. porcinae can be distinguished from L.manihotivorans and L. camelliae by its carbohydrate fermentation profile, absence of growth at

45 độ C, and production of D- and L-lactate as end products of glucose metabolism

8. Tóm tắt nội dung: An important part of the daily nourishment in Vietnam constitutes of fermented vegetables. Bacteria and especially lactic acid bacteria play a central role in the production of many fermented vegetables. The current study was conducted to investigate the diversity of native lactic acid bacteria (LAB) populations in ‘dua muoi’ (mustard and beet fermentation) and ‘ca muoi’ (eggplant fermentation), three types of popular traditional fermented vegetables of Vietnamese origin. To this end a polyphasic approach combining matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) and pheS gene sequence analysis was used. In addition, denaturing gradient gel electrophoresis was performed as a culture-independent method to complement the observed culturable diversity data. A total of 881 LAB isolates were recovered from 21 different samples. Predominant LAB associated with ‘dua muoi’ and ‘ca muoi’ were identified as Lactobacillus fermentum(56.6%), Lactobacillus pentosus (24.4%) and Lactobacillus plantarum (17.1%). Less abundant species were Pediococcus pentosaceus (1.0%) and Lactobacillus brevis(0.5%). Species present less than 0.1% included Lactobacillus paracasei, Lactobacillus pantheris and Pediococcus acidilactici. In contrast to fermented mustard and beet with the highest prevalence of L. fermentum, the species most recovered from fermented eggplant samples was L. pentosus. In addition, an important degree of genetic variability within the different predominant species was observed and strain dependency correlating with the type of fermented vegetable or location of production could be demonstrated using multivariate statistics. This research gives an extensive and detailed inventory of the LAB diversity associated with the production of diverse Vietnamese fermented vegetables and demonstrates the influence of type of raw material and/or production location and conditions on this diversity.
