Abstract

Vitamins are an essential food source with excellent roles in the cellular metabolism and other essential nutrients required in food intake but cannot be synthesized by humans. There have been reports of some lactic acid bacteria (LAB) abilities with probiotic activities to produce food-grade vitamins. Our study aimed to investigate lactic acid bacteria (LAB) possessing antimicrobial activities and extracellular production of folate from different Nigerian fermented foods. LAB was assayed for their antimicrobial activities against clinical isolates of Escherichia coli and Salmonella typhimurium and their extracellular production of essential vitamins. Among the 43 isolates of LAB, two strains of Lactobacillus fermentum showed the highest inhibitions against the test bacteria and demonstrated the highest concentrations of extracellular vitamins production. The range of vitamins produced at 24 h was between 12.23 and 801.79 μg/ml, while the highest vitamin production of 801.79 and 310.55 μg/ml was observed for folate and vitamin B12 respectively, the lowest production was for B1+B2. Consistent vitamin production was typical with only L. fermentum MT903311 and L. fermentum MT903312, so were their antimicrobial activities. The L. fermentum strains isolated in this study could be exploited and applied in food products to substitute synthetic vitamin enrichment and fortification.
