Bacillus coagulans, earlier known as L.sporogenes* was first isolated and described in 1933 by L.M. Horowitz-Wlassowa and N.W. Nowotelnow and the name was accepted in the fifth edition of " Bergey’s Manual of Determinative Bacteriology". But based on the characterization, biochemical aspects and other hybridization techniques,the species has been catalogued in the Bacillus species, in the seventh edition of Bergey's Manual. However, it was transferred to Bacillus coagulans in the seventh edition of Bergey’s manual due to simplification in cataloging. But in honor of the original discoverers, the name Lactobacillus sporogenes* is used for taxonomical purposes. According to the Eighth Edition of Bergey’s Manual of Determinative Bacteriology, "Various spore-bearing rods which produce lactic acid, are facultative or aerobic and catalase positive, have been assigned to the genus Bacillus.

"The characteristics of L. sporogenes* as cited in Bergey’s Manual (Seventh Edition) and other sources are: "Gram – positively spore-forming rods 0.9 by 3.0 to 5.0 micron size, aerobic to microaerophilic, producing L(+)-(dextrorotatory) lactic acid homofermentatively." Since L. sporogenes* exhibits characteristics typical of both genera Lactobacillus and Bacillus, its taxonomic position between the families Lactobacillaceae and Bacillaceae has often been discussed. This, along with the fact that there is no universally accepted official classification leaves room for controversy in the nomenclature.
