Abstract. Lactic acid bacteria (LAB) have the ability to synthesize water-soluble vitamins, including B vitamins such as folate, riboflavin, and vitamin B12. The characteristic of effective synthesis of vitamin B9 from SKB used in the test was L. plantarum KA3 (0.035288 μcg/ml), L. plantarum TK1 (0.028542 μcg/ml), L. lactis TV (0.028500 μcg/ml), A. kunkeei (0.042034 μcg/ml) and E. faecium 1 (0.127141 μcg/ml) strains were determined.
