The author isolated the fat-splitting bacteria from putreying fish, fresh milk and soil, and examined their activities of decomposing fat and triacetin.1) It has been found that the following bacteria are intensely active in splitting fat : Pseudomonas fluorescens from putrefying fish, Alcaligenes sp., Pseudomonas sp. and Achromobacter sp.from fresh mild and Pseudomonas aeruginosa, Serratia sp. from soil. Among them, Pseudomonas sp. No. 13 straiin had the most powerful triacetin hydrolase activity.2) Triacetin hydrolase of Pseudomonas sp. No. 13 strain was specific for triacetin and did not attack other esters of fatty acids. This enzyme was completely destroyed at 100℃ for 15 min, and it had the optimum temperature at about 55℃, and the optimum pH at about 7.0. The triacetin hydrolase of this bacterium was equivalent to about one seventh of commercial steapsin in its activity, and more active than that of Mycobacterium sp.
