Impact of Lactobacillus cultures on production of B-vitamins, organic acids and biotransformation of soy isoflavones

Abstract In the study, four potent Lactobacillus cultures of L. rhamnosus K4E, plantarum RD7, fermentum K7, and K16 were considered for production B-vitamins, organic acids biotransformation soy isoflavones. RD7 showed highest B 2 (0.84 μg mL −1 ) after 36 h, while exhibited maximum 12 (0.084 h. K4E produced 0.24 folate Highest lactate (16.43 acetate (5.86 was reported by K4E. butyrate (0.253 compared to other cultures. The bioconversion aglycones with 55.43% daidzein 72.30% genistein, during soymilk fermentation. These have a potential be used as functional starter fermented foods.
