The ABTS radical scavenging activity in samples fermented by B. subtilis KFRI 1124 (31.6%) and KFRI 1127 (32.7%), in P. pentosaceus LY 011 (27.9%) and L. gasseri KCTC 3162 (25.5%) were all higher than that in the control group (15.2%), showing that fermentation increased ABTS radical scavenging activity.
