Acetone–butanol–ethanol (ABE) fermentation was performed with sugarcane bagasse (SCB) hydrolysate using Clostridium beijerinckii strains. A cost‐effective SCB medium was developed with no enzymatic hydrolysis and no supplementation of extra carbon source or expensive nitrogen source. One of the C. beijerinckii strains studied was able to produce butanol with butanol productivity of 1.23 g/L/day with butanol yield of 0.18 g/g of sugars from the developed medium. High utilization rate of both glucose and xylose was observed in SCB medium during ABE fermentation. This study shows that SCB is a promising substrate for cellulosic biobutanol production.

拜氏梭菌菌株从甘蔗渣中生产生物丁醇。

丙酮-丁醇-乙醇（ABE）发酵是使用蔗糖梭菌（Clostridium beijerinckii）菌株与甘蔗渣（SCB）水解产物进行的。开发了一种经济高效的SCB培养基，无需酶水解，无需补充额外的碳源或昂贵的氮源。研究的其中一种拜氏梭菌菌株能够从开发的培养基中生产丁醇，其丁醇生产率为1.23 g / L /天，丁醇产量为0.18 g / g糖。在ABE发酵过程中，在SCB培养基中观察到了葡萄糖和木糖的高利用率。这项研究表明，SCB是纤维素生物丁醇生产的有前途的底物。
