With the aim to find new riboflavin producing starter cultures, selected strains were inoculated in milk and whey based media and evaluated for technological attributes. The study of new probiotic strains for their technological relevance and use in dairy products is important for trade and industry. Eight lactobacilli strains isolated from dairy and non-dairy sources were selected for milk coagulation, percent acidity, exoploysaccharides production, proteolytic activity and antifungal activity. The tested strains displayed appreciable starter activities. Among the tested strains, Lactobacillus fermentum KTLF1 and Lactobacillus muocase KTLF5 were the prolific riboflavin producers in milk (1.5mg/lt) and whey (0.83mg/lt). These riboflavin producing isolates displaying starter properties may be extended to a wide range of dairy-based, cereal based foods, feed, and beverages that that could in turn be used as an alternative to fortification with the controversial synthetic chemical riboflavin.
