摘要
利用丙酮丁醇梭菌（Ｃｌｏｓｔｒｉｄｉｕｍａｃｅｔｏｂｕｔｙｌｉｃｕｍ）Ｃ３７５菌株发酵稻草酶法水解液，分别研究了氮源、生长因子、ｐＨ等因素对发酵的影响。结果表明，在稻草水解液还原糖浓度为４．２８％时，总溶剂为１２．８ｇ／Ｌ，溶剂组成：丁醇∶丙酮∶乙醇＝６５．８∶２３．８∶１０．４，溶剂生成率为２９．９％。
The factors of nitrogen sources,growth factors and pH affecting acetone butanol fermentation of rice straw enzymatic hydrolysate by Clostridium acetobutylicum C 375 were studied.Under the optimum condition,the total solvent content was 12.8 g/ml (consist of butanol∶acetone∶ethanol=65.8∶23.8∶10.4),yield 29.9%.
