We often receive queries on the exact microbiological nature of LactoSpore^® (Sabinsa’s probiotic product containing Lactobacillus sporogenes, sometimes called (Bacillus coagulans). L. sporogenes was first isolated and described in 1933 and the name was accepted in the fifth edition of "Bergey’s Manual of Determinative Bacteriology", a constantly changing catalog for microorganisms. It was transferred to Bacillus coagulans in the seventh edition of this manual due to simplification in cataloging. However, to honor the original discoverers, the name Lactobacillus sporogenes is used widely, except for taxonomical purposes. LactoSpore^® thus contains a food derived lactic acid producing strain rather than a soil-derived antibiotic producing Bacillus.
