The authors observed that a mixture of Sake and synthetic medium composed of amino acids, bases, vitamins and Tween 80 was suitable for the growth of Hiochi-bacteria (putrefactive bacteria of Japanese Sake). However, in the mixture devoid of Tween 80,the Hiochi-bacteria could not grow more vigorously than in pure and single Sake.This paper deals with the relation between the effect of various surface-active agents on the growth of Hiochi-bacteria and their chemical structure.The results with six kinds of surface-active agents showed that Brij 35 exerted an inhibitory action and that Tween 40,60 and Mirj 52 were not effective, while Tween 80 and 85 stimulated the growth of the bacteria.From these facts, it seems likely that the growht-stimulating activity of surface-active agents would be closely related to some definite fatty acids existing in their molecules.In an additional experiment, it was observed that the single addition of unsaturated fatty acids having eighteen carbon atoms, such as oleic, linolic and linoleic acids, was not effective for the growth of Hiochi-bacteria, but when used in combination with Tween 40 or 60,all of them exerted an effect similar to that of Tween 80.These observations suggest that the grwoth-stimulating effect of Tween 80 would be due to the synergetic action of oleic acid moiety as stimulant and its own permeability.
