Inhibition of E. coli Growth
LAB are known to have an antibacterial effect against
harmful bacteria. Such an inhibitory function is achieved
by bacteriocin, a substance that LAB produce. The growth
of E. coli in the presence of the LAB strain was gradually
inhibited for 6-9 h, but the growth rapidly decreased after
12 h. E. coli was not detected after 18 h (Fig. 2). Other
