Cellulases from some fungi have been reported by many investigators. Recently, it was found by the authors that a strain of Aspergillus saitoi excreted a remarkable amount of cellulase in a tank culture broth.The present report concerns the action of this partially purified cellulase towards any substrate i.e., swollen cellulose, sodium carboxymethyl cellulose and salicin.The pH optimums for each of the above substrates were found to be situated at 3,4 and 5,and so the temperature optimums were at 50,45 and 60°respectively.As concerns the stability, the aqueous solution of these enzymes were found to be stable over the ranges of 3.5-6.2,2.8-6.5 and 3.0-6.0 , and also to lose these activity by 50,20 and 12 percent in 10 minutes at 60℃.Furthermore, it was observed that the unpurified preparation consisted of at least from three to four parts by electrophoresis.
