Method for producing useful substance from cellulose-containing material

摘要

The present invention provides a method for producing a useful substance efficiently from cellulose without using any cellulase preparation. According to the disclosures of the present specification, in the production of a useful substance from a cellulose-containing material, the cellulose-containing material is brought into contact with an ionic liquid to cause the ionic liquid to permeate the cellulose-containing material, and a carbon source comprising the cellulose in the cellulose-containing material is simultaneously saccharified and fermented by a cellulase-producing microorganism in the presence of the ionic liquid.

1. A method for producing a useful substance from a cellulose-containing material, comprising:
bringing a cellulose-containing material into contact with an ionic liquid to cause the ionic liquid to permeate the cellulose-containing material; and simultaneously saccharifying and fermenting a carbon source in the presence of the ionic liquid that comprises the cellulose in the cellulose-containing material using a cellulase-producing microorganism to produce the useful substance, wherein a concentration of the ionic liquid ranges from 50 to 500 mM, and wherein the useful substance produced is selected from the group consisting of alcohols, organic acids, glycerin, and plastics.
