First Claim
Patent Images
1. A method of processing lignocellulosic material, comprising the steps of:
- combining in a reactor a sample of lignocellulosic material and a cellulose-degrading or a hemicellulose-degrading bacterium, resulting in a mixture; and
maintaining said mixture at a temperature for a period of time, resulting in a liquid product, and a solid product.

Abstract
Aspects of the present invention relate to methods of microbially treating lignocellulosic biomass using cellulose- and/or hemicellulose-degrading bacteria. In certain embodiments, the microbially treated material is then subjected to thermal and/or chemical pretreatment. In tandem with the microbial treatment the thermal and/or chemical pretreatment may result in the production of fewer degradation products, thereby allowing for higher overall yields of ethanol per ton of starting biomass.
