纤维质原料制燃料酒精的研究进展

将纤维素生物质转化为燃料酒精，可以降低传统以粮食为原料的酒精发酵工业的成本，充分利用这种数量巨大的可再生资源。纤维素酶将预处理的纤维质原料降解为酵母可直接利用的D-葡萄糖，转化为酒精。对纤维质原料制酒精的研究主要有原材料的预处理、如何降低纤维素酶的成本、发酵过程的优化、茵种的合理运用和改造、酒精废糟的综合利用。

Study Progress of Fuel Alcohol Production by Cellulose

Cellulose, instead of traditional grains, was used in fuel alcohol production by biotransformation , which could reduce production cost. And such plentiful renewable resource should be fully utilized. The pretreated cellulose was degraded into D-glucose by cellulase and then converted into alcohol eventually. The research on fuel alcohol production by cellulose mainly included: pretreatment of raw materials; the approaches to reduce the cost of cellulase; optimization of fermentation process; proper use and transformation of microbial species; and comprehensive utilization of waste distiller's grains.
