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. |

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. |

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. |

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.

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. |

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

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. |
