Abstract
The present investigation was conducted to assess lactic acid bacteria present in traditionally fermented food of ethnic tribes in India for probiotic properties, antibacterial activity, and antibiotic tolerance behavior. Enterococcus sp., Lactobacillus sp., and Lactococcus sp. showed antibacterial activity against Bacillus cereus MTCC 430, Staphylococcus aureus subsp. aureus MTCC 740, and Salmonella enterica ser. paratyphi A MTCC 735. Lactococcus sp. and Lactobacillus sp. could tolerate acidic conditions (pH 2) and high bile salt concentration (4000 ppm). The lactic microflora were found to be sensitive to most common antibiotics, except for cloxacillin (5 μg), cephalexin (30 μg), and cephalothin (30 μg).
