Bacillus subtilis SNZ 1972 was originally isolated from the soil by Sanzyme Biologics after extensive screening and characterization of various strains of Bacillus subtilis.Bacillus subtilis is a rod shaped, probiotic bacterium. It is found in the soil like most members of the Bacillus family and the gastrointestinal tract of ruminants and humans. Bacillus subtilis bacteria secrete commercially important industrial enzymes such as amylase, protease,pullulanase, chitinase, xylanase, lipase, among others. Bacillus subtilis is also responsible for producing antibiotics like bacitracin (effective against Gram-positive bacteria), polymyxin (affective against Gram-negative bacteria), difficidin (a broader spectrum), subtilin, and mycobacillin.
