Assessment of probiotic properties of Lactobacillus fermentum CM 36 Isolated from camel milk

Lactic acid bacteria (LAB) are known to possess probiotic potential and play a significant role to combat intestinal pathogens. The objective of the present investigation was to isolate, characterize and screen lactobacilli associated with camel milk for probiotic properties such as antibacterial activity, bile tolerance and antibiotic resistance. Among various isolates screened Lactobacillus fermentum CM36 showed remarkable antibacterial activity against B.cereus, B.subtilis, and E.coli in supernatant even after neutralization and protease treatment confirming bacteriocin activity. L. fermentum CM36 tolerated oxgall up to 0.4% (w/v) and showed resistance to various antibiotics used in the study. L. fermentum CM36 showed potential for antibacterial and thus, bile tolerance and may be further explored for its benefits towards animal and human health.
