摘要
利用 Klebsiella oxytoca菌发酵葡萄糖制得2,3-丁二醇发酵液,再将经过离心去除菌体的该发酵液进行蒸馏获得商品级甲乙酮,转化率为99％以上,收率95％以上。虽然该方法在产品成本上还无法与石油化工产品竞争,但可作为利用生物法生产燃料及化工原料的一种补充。
Fermenting liquor containing 2, 3 - butanediol is obtained by Klebsiclla oxytoca fermenting glucose. Commercial MEK is obtained. Through distillation of the fermenting liquor with bacteria in it centrifugally removed. The conversion is above 99% and yield is over 95% .
