The thiaminase activity of the culture supernatant of clostridia received from many institutes in Japan was examined. Some of the cultures labelled as Cl. aerofoetidum, an organism related closely to Cl. bifermentans, Cl. botulinum, Cl. chauvoei, Cl. saprogenes, Cl. sporogenes, Cl. tetanomorphum and unclassified organisms were found to produce thiaminase I.
