STUDIES ON THIAMINASE OF THE CLOSTRIDIUM

I. THIAMINASE OF CLOSTRIDIUM SPOROGENES

抄録

From the experiment presented in this paper it is evident that most strains of Cl. sporogenes and the organisms related closely to Cl. sporogenes produce extracellular thiaminase I. It will be worthy of note that the magnitude of the activity of the thiaminase of these organisms, the optimum temperature and pH were closely resembled to those of the enzyme of Cl. thiaminolyticum.
