Butyric acid has several potential applications in chemical industries and food technology. Currently, the most promising microorganism used for the bio-production of butyric acid is Clostridium tyrobutyricum. This microorganism is capable of producing butyric acid with high selectivity and can tolerate high concentrations of butyric acid. However, it is unable to use disaccharides such as sucrose as a carbon source. In this study, one strain of Clostridium diolis isolated from old fermented cow dung was screened and used in batch fermentation for the production of butyric acid using sucrose (50 g/l) as the sole carbon source. At pH 5.9, this strain was able to degrade all the sucrose in the medium to fructose and glucose and it produced 22 g/l of butyric acid. The yield also was promising. The drawbacks were relatively low tolerance to butyric acid as it was unable to consume the whole glucose and fructose in the medium and also slow production rate. At pH 6.8, the growth rate was faster, but the final conc. of butyric acid was only 13 g/l. In conclusion, this strain may be promising for the bio-production of butyric acid from sucrose.
