It was found by the authors that a strain (R-392) belonging to Rhizopus produces lipase and cellulase at the same time in submerged culture. The cellulase was purified by fractionation with ammonium sulfate and subsequent treatment with a column of Duolite A-7 followed by absorption on Amberlite XE-64,and a preparation having high activity was obtained.This enzyme is extremely stable in aqueous solution at various pH's and high temperature, for example, no loss of activity is observed in twenty-four hours at pH 10.6 or in three hours at 60℃. This enzyme acts on denaturated celluloses such as cellophane and sodium carboxymethylcellulose, but not on natural cellulose and cellobiose.
