Lactic acid bacteria play important roles in vegetable fermentation, whereas some yeasts have contributions to aromatic formation. However, the fermented products are sometimes spoiled by contamination of unknown bacteria during fermentation. In this study, we isolated three bacterial strains including KG 2.2, KG 2.3 and KG 2.5 in which their growth causes spoilage of the fermented pickles with formation of white biofilm layers. On basis of morphological and biochemical characteristics, these bacterial strains belong to Bacillus genus. The results from 16S rRNA gene sequencing indicated that the strains KG 2.2 and KG 2.5 areBacillus subtilis, KG 2.3 isB. amyloliquefaciens. In addition, we isolated three antibacterial yeast strains from the high-quality fermentedvegetable samples. These yeasts are able to strongly inhibit growth of the spoilage bacteria. One of these strains with the best antagonistic activity named L36 was characterized as Candida tropicalis based on the ITS sequence of rDNA. This is the first report about Candida tropicalishaving antibacterial activity against the food-spoilage bacteria. This yeast strain is a good candidate for preservation of traditional fermented vegetable products as a supplement. 2018-03-30T02:29:04Z 2018-03-30T02:29:04Z 2016 Article 2588-1140 http://repository.vnu.edu.vn/handle/VNU_123/61551 other Vol 32;No 1S application/pdf H. : ĐHQGHN |
