1. A method for the hydrolysis of cellulose to simple sugars which comprises:
- contacting in a reaction zone an aqueous slurry comprising from three to 20 weight percent of a solid cellulose containing charge stock with a cellulase enzyme complex wherein the concentration of said enzyme complex is greater than 0.1 units per milliliter of said slurry and wherein said contacting occurs in the presence of a mechanically produced shear rate of from 50,000 to 200,000 feet/minute/foot substantially throughout said reaction zone and wherein the cellulose content of said solid cellulose-containing charge stock is from 30 to 80 weight percent of said charge stock.

Abstract
Enzymic conversion of cellulose under mechanical shear rate of from 50,000 to 200,000 feet/minute/foot as imparted to the cellulose by a series of rotors and stators mounted in the reaction vessel improves yield of simple sugars.
