530415

Abstract:

A solid sorbent material comprising cellulose which has been modified by hydrolysis with a cellulase enzyme for a duration sufficient to increase the protein adsorption capacity of the solid sorbent material and methods for preparing the sorbent material. Methods for purifying a protein include passing a liquid medium containing the protein over the solid sorbent material are also included.

Abstract:

A process for treating cellulosic materials to obtain glucose therefrom, which process includes an initial acid or base treatment of the cellulosic materials to remove hemicellulose, followed by a solvent treatment of the solid residue to dissolve the native cellulose contained therein. The dissolved cellulose is separated from the solid lignin-containing residue, whereafter the cellulose is reprecipitated by contacting the solution thereof with water. The reprecipitated cellulose is hydrolyzed to glucose either by acid or enzyme hydrolysis. If desired, the cellulose may be reprecipitated and hydrolyzed in the presence of the lignin-containing solid, the latter being separated from the glucose.
