丙酮-丁醇-乙醇（ABE）发酵作为将可再生资源升级为有价值的基础化学品和液体燃料的一种方式，正在重新受到关注。厌氧发酵和非竞争性是潜在底物的理想特性，而木质纤维素生物质正好满足这一要求。使用代表木质纤维素生物质的水解产物的糖：己糖（葡萄糖和甘露糖）和戊糖（阿拉伯糖和木糖），进行单糖的分批发酵。转化过程的特征在于作为时间的函数的生物质，酸和溶剂的浓度以及pH值和总有机化合物。C.丙酮丁醇能够转化所有研究的糖。转化成溶剂的强烈增强的存在下，在发酵培养基中的碳酸钙。
The Acetone-Butanol-Ethanol (ABE) fermentation is receiving renewed interest as a way to upgrade renewable resources into valuable base chemicals and liquid fuels. Abundance and un-competitiveness with food sources are desired features of a potential substrate, and they are met by lignocellulosic biomass.This contribution is about the characterization of the ABE fermentation by C. acetobutylicum DSM 792 using sugars representative for hydrolysis products of lignocellulosic biomass: hexoses (glucose and mannose) and pentoses (arabinose and xylose).Batch fermentations of single sugars were carried out. The conversion process was characterized as a function of time in terms of biomass, acids and solvents concentrations as well as pH and total organic compounds. C. acetobutylicum was able to convert all investigated sugars. The conversion into solvents was strongly enhanced by the presence of CaCO3 in the fermentation medium.
