초록

A unique mesophilic Clostridium species strain BOH3 is obtained in this study, which is capable of fermenting monosaccharides to produce butanol and hydrolyzing polysaccharides to produce hydrogen (H<SUB>2</SUB>) and volatile fatty acids (VFAs). From 30g/L of glucose and xylose each, batch culture BOH3 was able to produce 4.67 and 4.63g/L of butanol. Enhancement treatments by increasing the inoculated cells improved butanol production to 7.05 and 7.41g/L, respectively. Hydrogen production (2.47 and 1.93mmol) was observed when cellulose and xylan (10g/L each) were used, suggesting that strain BOH3 possesses xylanolytic and cellulolytic capabilities. These unique features reveal the strain's novelty as most wild-type solventogenic strains have not been reported to have such properties. Therefore, culture BOH3 is promising in generating butanol and hydrogen from renewable feedstock.
