Probiotic properties in vitroof the Saccharomyces boulardii SB2 yeast, was isolated from fruit at Cuc Phuong National Park were evaluated based on biological characteristics and tolerance in simulated intestinal conditions. In the present work, studies were carried out to improve cell growth kinetics to produce cell mass of this biotherapeutic yeas...

During the study on yeast diversity from natural samples in Viet Nam, we have collected 38 samples of flowers, fruits, leaves, litter and soils in Con Dao Island and isolated 54 yeast strains. They were identified based on morphology observation and sequences of D1/D2 domain of 26S rDNA. The results showed that they belonged to 13 genera, 28 specie...

Bacillus velezensis is one of the members of the Bacillus subtilis species complex which is generally considered as safety organism. The bacterium possesses several beneficial properties for crops, especially production of antifungal and antibacterial agents against plant pathogens. In this study, we aimed to investigate the biological properties o...

The roles of microorganisms in traditional alcoholic fermentation are often assumed based on abundance in the starter and activity in pure culture. There is a serious lack of hard evidence on the behavior and activity of individual microbial species during the actual fermentation process. In this study, microbial succession and metabolite changes d...

Strain VN07A0015(T) was isolated from soil collected on Cat Ba Island, Vietnam. The taxonomic position of strain VN07A0015(T) was near Streptomyces aomiensis (98.5% similarity) and Streptomyces scabrisporus (95.6%), and it clustered within them; however, this cluster was distant from the type strains of other Streptomyces species. The aerial myceli...

Actinomycetes were isolated from 109 soil and 93 leaf-litter samples collected at five sites in Vietnam between 2005 and 2008 using the rehydration-centrifugation (RC) method, sodium dodecyl sulfate-yeast extract dilution method, dry-heating method and oil-separation method in conjunction with humic acid-vitamin agar as an isolation medium. A total...

VY-68, a ballistoconidiogenous yeast strain, isolated from a plant leaf at Cuc Phuong National Park of Ninh Binh Province, Vietnam, was assigned to the genus Bullera based on morphological and chemotaxonomical characteristics. Based on the sequence analyses of 18S rDNA, D1/D2 region of 26S rDNA, and internal transcribed spacer regions (ITS), VY-68...

Five ballistoconidiogenous yeast strains, isolated from plant leaves at Cuc Phuong National Forest of Ninh Binh, Vietnam, were assigned to the genus Kockovaella based on morphological and chemotaxonomical characteristics. They represent four new species based on analyses of 18S rDNA sequence, sequences of internal transcribed spacer regions, and DN...
