| 摘 要： | 以诱变选育的1株突变菌株丙酮丁醇梭菌XY16为对象,对影响该菌发酵特性的相关因素(N源、生长因子、热激)进行研究。结果显示:无机N源乙酸铵比其他N源更有利于丙酮丁醇的发酵,玉米浆或玉米蛋白可以直接替代生长因子进行丙酮丁醇发酵,热激可以提高总溶剂产量,最高可以达到21.28 g/L。该菌还可以同时利用葡萄糖和木糖,当葡萄糖利用完后,木糖才能被有效利用。

| Abstract: | Influence of nitrogen source,growth factor and heat shock affecting fermentation characteristics of a mutant strain Clostridium acetobutylicum XY16 were investigated.The results showed that inorganic nitrogen source ammonium acetate was more suitable for fermentation compared with other nitrogen sources.Corn steep liquor or zein could replace growth factors;heat shock to XY16 could enhance total solvent production with 21.28 g/L.In addition,the mutant XY16 could utilize glucose and xylose at the same time,t... |
