Effects of acetic and butyric acids on solvents production by Clostridium acetobutylicum

Biotechnology Letters Aims and scope Submit manuscript

Summary

The fermentation of glucose by Clostridium acetobutylicum on a synthetic medium is carried out with a conversion of carbon source into solvents of 32 %. The ratio of butanol, acetone and ethanol products is approximately 0.6 - 1.9 - 6. The synthetic medium supplemented with acetic acid at a concentration of 2 g/l increases acetone formation and the ratio of products is approximately 0.5 - 3 - 6 with a conversion of glucose into solvents of 34 %. The addition of 2 g/l butyric acid permits obtaining a distribution of 0.8 - 2.4 - 6, with a conversion of 35 %.
