玉米浆干粉在葡萄糖和木糖混合丙酮丁醇发酵中的应用
Application of dry powder of corn steep water in the butanol fermentation by Clostridium acetobutylicum
摘要
Abstract
Fermentative production of butanol by Clostridium acetobutylicum using dry powder of corn steep water(DCSW)was investigated to reduce production cost.In a batch-scale fermentation,11.21 g/L of butanol were produced by Clostridium acetobutylicum from an optimized 50g/L glucose-2.5 g/L DCSW,and 17.57 g/L of total solvents(acetone,butanol,and ethanol)was obtained.Initial fermentation in small-scale flasks with 30 g/L glucose+20 g/L xylose-2.5 g/L DCSW medium yielded 11.10 g/L of butanol and 16.83 g/L of total solvents.DCSW can serve as an economic source of nitrogen,vitamins,amino acids,minerals,and other nutrients for cellulosic biofuel butanol.关键词
