DUAL STEP PROCESS FOR PRODUCTION OF BUTANOL FROM LIGNOCELLULOSIC BIOMASS USING CLOSTRIDIUM BEIJERINCKII

摘要

The present disclosure provides a two step process for production of butanol comprising the steps of: a) low temperature pretreatment of lignocellulosic biomass; and b) simultaneous saccharification and extractive co-fermentation (SSECF) of the pretreated lignocellulosic biomass, wherein the saccharification, the fermentation and the extraction are carried out in a single vessel. The fermentation is carried out by a wild type micro-aero-tolerant strain of Clostridium beijerinckii.
