Four Bacillus coagulans strains were isolated from plant-based sources and screened for
heat resistance, in vitro probiotic properties and toxicological characteristics and compared
with B. coagulans GBI-30, 6086. These strains survived high temperatures and low pH, were
resistant to bile and lysozyme, were able to produce biofilm, had antimicrobial activity, and
were antibiotic-sensitive. All strains had the properties of adhesion, auto-and co-
aggregation, although the level of each varied and with incubation time. The safety of these …
