Bacillus polyfermenticus SCD which is commonly called as Bisroot strain is being used for functional foods through the treatment of long-term intestinal disorders, since the live strains in the form of active endospores can successfully reach the target intestine in humans. The cells of B. polyfermenticus SCD were treated for 4h in artificial gastric juice (pH 2.0,3.0) and bile acid. Final viability of the strain in artificial gastric Juice (pH 2.0, 3.0) is reached to 62.8% and 81.2% respectively B. polyfermenticus SCD is resistant to antibiotics such as streptomycin, rifampicin, nystatin and ampicilin. B. polyfermenticus SCD is well known supplies the nutrients by synthesizing vitamin $B_1$, $B_2$, C and K. B. polyfermenticus SCD produces various digestive enzymes and the enzymes enable to completely digest diets in our body. Above all, $\alpha$-amylase and pretense activities are very higher than B. subtilis KCTC 1020, about two fold and twenty five fold respectively. B. polyfermenticus SCD is very stable during long-term storage period in phosphate buffers of wide-range pH, solutions of various concentrations of sodium chloride, 5% glucose solution and water.
