Cellobiose inhibits the hydrolysis of cellulose by filtrates of most of the organisms tested. Glucose does not inhibit the hydrolysis. The action of cellobiose is believed to be that of an end product inhibiting an enzymatic hydrolysis, in much the same manner that maltose inhibits hydrolysis of starch by α-amylase. Filtrates of seven organisms (of 36 tested) have been found where the hydrolysis of carboxymethyl cellulose is stimulated by low cellobiose concentrations. As the cellobiose concentration was increased, the stimulation decreased, and finally inhibition occurred. The hydrolysis of unsubstituted cellulose by these same filtrates is inhibited by cellobiose. [ABSTRACT FROM AUTHOR]
