Simultaneous Saccharification and Fermentation (SSF) of Cellulose from lignocelllulise for 2nd Bioethanol Production: A Review

摘要

Lignocellulosic materials, a abundant and renewable resources in the world, can be utilized for 2nd bioethanol production. Simultaneous saccharification and fermentation (SSF) has been regarded as a promising process for bioethanol production. This article reviews the status of SSF process for bioethanol production and its challenges for reducing production cost and increasing process efficiency, and the key issues mainly including high loading of cellulose substrate, high temperature of SSF reaction and its corresponding thermo-tolerant microorganism as well as alleviation or elimination of inhibitors have been analyzed. At last future prospects for commercialization of the 2nd bioethanol production by lignocellulosic materials with low capital investment are stated.
