With a view of practical application, we tried several methods for improving the yield of caproic acid, using somewhat impure strains which were on the way of purification from soils and muds, and obtained following results.(1) By the method of heat shocking, followed by successive fermentation the fermentation degree ((alcohol consumed)/(alcohol used)) and the yield of caproic acid ((caproic acid formed)/(alcohol consumed)×(138)/(116)) were imprived to 90% and 85% respectively.(2) Heat shocking (100℃, 60 sec, ) is an efficient method for purification of caproic acid clostridia.(3) Fermentation degree, and yield of caproic acid upon the alcohol basis, were improved when small amount of acetic acid (1/100〜1/15 part of alcohol) had been added to the alcohol medium.(4) As the inoculum, it is desirable to use young and active culture which is at the growing state. By this method, values of 93% as fermentation degree and fairly 100% as the yield of caproic acid are obtainabel.
