Process for biofuel and biochemical production， culture medium and biofuel and biochemical produced

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.

本发明涉及一种利用木质纤维素生物质（lignocellulose biomass）发酵制备生物燃料与生物化学品的工艺及培养基。该工艺采用由固体纤维浆、水解液与多肽复合物复配而成的固液混合体系。固体纤维浆可被该多肽复合物部分降解，一方面为微生物固定化提供载体，另一方面释放可调控梭菌（Clostridium）群体感应（quorum sensing）通路的物质。本工艺与培养基可提升生物燃料及生物化学品的生产效能，实现丁醇（butanol）、丙酮（acetone）等产物的规模化工业生产。
