Isolation of a Potential Probiotic and Evaluation of Its Exopolysaccharide for Antioxidant and α-Glucosidase Inhibitory Activities.

The probiotic properties of ten lactic acid bacteria and antioxidant and α-glucosidase inhibitory activities of the exopolysaccharide (EPS) of the selected strain were investigated in this study. L010 was one of the most active strains across all the in tests. The cell-free supernatant (50 g/l) of L010 showed high levels of both α-glucosidase inhibitory activity (98.

Isolation of acid tolerant lactic acid bacteria and evaluation of α-glucosidase inhibitory activity.

In this study, lactic acid bacteria strains (LABs) were isolated from Korean traditional fermented food and examined as potential probiotics using in vitro methods. Ten LAB strains survived in de Man, Rogosa and Sharpe broth adjusted to pH 2.5 were tested for resistance to acidic conditions and bile, antimicrobial activity, and α-glucosidase inhibitory activity.
