| Abstract: | In the experiment, two caproic acid bacteria strains were isolated from aged pit mud of Jinjiu and their culture conditions were optimized. The results revealed that, the growth of caproic acid bacteria was the best and its caproic acid yield was the highest as pH value was 6, alcohol content was 3 %vol, culture temperature was at 34 ℃, and peptone content was 4 g/L. |
