Abstract
Recently, Chang isolated one strain from 15 Pakistani, 9 strains from 28 Formosan feces of aerobic spore forming bacillus having thiaminase and reported these organisms should belong to one new species with many properties different from Bacillus thiaminolyticus. Bacteriological and enzymological investigations were carried out on these strains (P and T_3) supplied from Chang and on the m strain of B. thiaminolyticus in very detail, and we evidenced that, though, P and T_3 strain in a way with morphological, cultural and biological characteristics differ from m strain, these organisms should belong to B. thiaminolyticus because the differences were not so distinct to decide that strains make a new specis of the Genus Bacillus.
