Butanol fermentation with wheat starch wastewater
摘要
Abstract
In order to reduce the production cost of butanol fermentation,low concentration of wheat starch wastewater was used to produce butanol, acetone and ethanol with Clostridium acetobutylicum. Medium was optimized according to the composition of starch wastewater. Effects of cassava concentration、nitrogen source and concentration, inorganic salt and the method of raw material pretreatment were investigated. Addition of 70 g/L cassava, 2 g/L yeast extract powder and 1 g/L K2 HPO4 to low concentration wastewater gave better performance,the yields of butanol and total solvent in flask were able to arrive at 14�72 and 22�65 g/L,respectively. Meanwhile,the yields of butanol and total solvent in a 7⁃L fermentor could achieved 13�51 and 23�13 g/L. Through extractive fermentation, the yields of butanol and total solvent reached 15�13 and 29�38 g/L,respectively.关键词
