Abstract:

This invention relates to a novel process for the rapid and complete hydrolysis of cellulose into glucose, cellobiose, and other simple sugars and for the separation of the sugar products free of the other reactants. A method of enzymatically converting cellulose to simple sugars wherein finely divided dry cellulose, less than 150 micron particle size, is combined with a concentrated cellulase enzyme solution obtained from Trichoderma viride QM 9123 to form a slurry having a cellulose solids content of 10 to 30 percent, and after hydrolysis the soluble sugar components are removed by pressure filtration through a molecular sieve membrane without any enzyme passing in the effluent.
