Cellulase AN

I.U.B. 9012-54-8


The cellulase enzyme used by National Enzyme Company is a food grade cellulase complex obtained by the controlled fermentation of Aspergillus niger. It hydrolyzes the beta-D-,4- glucosidic bonds of cellulose, its oligomers and derivatives.


One FCC Cellulase Unit (CU) is that activity that will produce a relative fluidity change of one in five minutes in a defined carboxymethyl cellulose substrate under the conditions of the assay. This assay is based on the enzymatic hydrolysis of the interior beta-1,4-glucosidic bonds of a defined carboxymethyl cellulose substrate at pH 4.5 and 40°C. The corresponding reduction in substrate viscosity is determined with a calibrated viscometer.


This enzyme’s primary use is as a digestive aid, particularly in animals. Cellulase is also used to produce glucose syrups and in paper milling. Research is going on to determine the possible use of this enzyme in the treatment of wastes. The end product of this reaction is glucose.

Shelf Life:

To maintain optimum enzyme activity, this product should be stored in a cool, dry place in a tightly sealed container. When properly stored, this product can be expected to lose less than 10% of its activity in twelve months.
