PROCESS FOR BIOFUEL AND BIOCHEMICAL PRODUCTION, CULTURE MEDIUM AND BIOFUEL AND BIOCHEMICAL PRODUCED

摘要

The present invention relates to a process and a culture medium for biofuel and biochemical production by fermentation of lignocellulose biomass. The process describes the use of a solid-liquid mixed blend formed by solid fiber pulp, hydrolysate, and a polypeptide complex. The solid fiber pulp is partially degraded by the polypeptide complex allowing microbe immobilization and, at the same time, releasing substances that affect Clostridium quorum sensing pathways. The present process and culture medium allow the improvement of biofuels and biochemical production, as butanol and acetone in an industrial scale.

主权项

1. A process for converting lignocellulosic biomass into a biofuel and/or a biochemical comprising: (1) submitting the lignocellulosic material to a pulping process, to obtain pulp; (2) submitting additional lignocellulosic biomass and/or fiber pulp to a hydrolysis process, to obtain hydrolysate; (3) mixing the pulp with the hydrolysate, to obtain a culture medium; (4) adding a polypeptide complex into the culture medium; (5) adding a fermentative microbe into the culture medium, to obtain a fermentation medium;
(6) fermenting the fermentation medium to produce fermentation products; and (7) optionally recovering the fermentation products.
