Abstract
The study was conducted to assess the antimicrobial potential of lactic acid bacteria against Bacillus cereus. Lactococcuslactis, yoghurt cultures, strains of Streptococcus, Leuconostoc and two strains of Lactobacillus were studied. Crude extract from LAB, containing antimicrobial metabolites were tested by well diffusion method. The maximum inhibitory zone of 16.33±0.88 mm was observed with metabolites of yoghurt culture. The inhibition zone for L. lactis, Leuconostoc, Lactobacillus (L-2), Streptococcus and Lactobacillus (L-1) were 14.67±2.73mm, 15.33±0.33mm,14.33±1.86mm, 14±1.53mm and 13.33±2.40 mm respectively. Although the difference was non-significant, proving that all the LAB cultures were equally active against B. cereus.
