Abstract
This study aimed to determine the antibacterial power produced by isolates of lactic acid bacteria from kefir of cow's milk and soy milk on Escherichia coli. This research was conducted in four stages, namely isolation and identification of kefir BAL, antibacterial substance production from isolates, testing the inhibition of BAL antibacterial isolates against Escherichia coli. The results showed that the sixth lactic acid bacterial isolate from soybean kefir and cow's milk kefir was able to inhibit the growth of Escherichia coli in acidic and neutral conditions. In acidic conditions, the KE1-KE3 inhibition zone is 3.51; 2.93; 2,66 and SA1-SA3 are 1,83; 2.46; 2.46. In the neutral condition of the KE1-KE3 inhibitory zone, respectively 1.59; 2.33; 1,99 and SA1-SA2 are 1,49; 2.49; 2.39.
