FUNCTIONAL AND PROBIOTIC POTENTIAL OF INDIGENOUS BACILLUS COAGULANS AND BACILLUS PUMILUS STRAINS
Journal Title: International Journal of Microbiology Research - Year 2016, Vol 8, Issue 3
Abstract
The spore forming Bacillus species have created enormous interest as probiotics in the recent years, because of it’s most important character of thermo-stability that assures its viability in the finished product. Thus, we aimed to explore functional and probiotic properties of indigenous Bacillus coagulans (n= 32), Bacillus pumilus (n= 2) and Bacillus subtilis (n= 2) strains. Intrinsic functional properties like acid and bile salt tolerance, cell surface hydrophobicity and rate of acid production for survival and action in the gut were investigated in-vitro for thirty six isolates. Further, we screened the best ten Bacillus strains and studied extensively for their different probiotic attributes and made a comparative account. Based on the relative probiotic performances, Bacillus coagulans B37 and Bacillus pumilus B9 (both isolated from buffalo milk) were appeared to be well adapted to the gastro intestinal environment and found to deliver good probiotic attributes, especially for antibacterial, hypocholesterolemic and ï¢-galactosidase enzyme activities. Though majority of Bacillus species still claims better niche and requires Generally Recognized as Safe (GARG) status, these two new indigenous strains, B. coagulans B37 and B. pumilus B9 might be potential for probiotic use after proper clinical studies and safety assessment in animals and human.
