  • Via enrichment procedures carried out on a dioxin contaminated sediment sample from lotus pond at Danang airport, a microbial community assigned as DN553 with high capability of carbazol degradation was established. Analyses of community structure by using denaturing gradient gel electrophoresis (DGGE) of 16S rDNA fragments indicated that Achromobacter and Alcaligenes species dominated in this enrichment culture. In addition to carbazol, the enrichment culture was also able to utilize other PAH compounds such as naphthalene and phenanthrene as the only carbon and energy sources. In the presence of different PAH as growth substrates, the community structure changed accordingly, however...

  • Alcohol fermentation was carried out with sticky rice using 15 most popular sorts of yeast cakes in Vietnam to produce different kinds of alcoholic beverages. The products were obtained by traditional distillation method and compared with each other for flavour and taste according to the standard qualification scale for alcoholic products. It revealed that Ruou Can yeast cake which has been widely used for hundreds years by local commirnities yielded the best product and therefore was selected for further studies...

The products were obtained by traditional distillation method and compared with each other for flavour and taste according to the standard qualification scale for alcoholic products. It revealed that Ruou Can yeast cake which has been widely used for hundreds years by local communities yielded the best product and therefore was selected for further studies. From this yeast cake, two yeast strains were first time isolated and identified as Saccharomyces cerevisiae and Saccharomycopsis fibuliger based on morphology and 26S rDNA D1...

  • From 53 samples (13 of leaves, 18 of litters and 22 of soils ), which were collected in Phongn ha - Keb ang National Park, 57 yeast strains were isolated. Those yeast strains were identified based on the morphological characteristics and the sequence analysis of D1/D2 domain of 26S rDNA. They belonged to 13 genera and 26 species, of which 5 were suspected as new species. A mong 13 genera , Basidiomycetous yeasts were dominant from isolated samples . Thirty - four strains out of 57 were mainly grouped into 3 genera of Rhodotorula, Sporobolomyces, Candida and 11 species. The other 18 strains belonged to t...

  • Bacterial community in dioxin contaminated soil and mud samples from Danang airport was enumerated and studied for their potential degradation capability against three-ring compound carbazol. The cell number was determined on nutrient rich medium and on mineral medium supplemented with carbazol. It has been showed that number of cells presented in mud samples was significantly higher than in soil samples, in the range of 1 magnitude order. About 50% of the total cell number in each sample grown on the medium with carbazol. Analyzing 12 representative strains selectively isolated on the carbazol containing medium by using the ARDRA method with two endonucleases HaeIII and MspI showed t...
