The Pyrolase® cellulase is a broad spectrum enzyme which can be employed in a variety of industrial applications. The Pyrolase® cellulase product operates at higher pHs and temperatures than conventional enzymes of this class. It is useful for the breaking (or hydrolysis) of beta-linked carbohydrates such as guar gum, derivatized guar and carboxymethyl cellulose. Source
The action pattern of the enzyme includes both endoglycosidase and exoglycosidase activities, allowing it to effectively reduce viscosity by cleaving within long polysaccharide chains and also by cleaving disaccharide units from the ends of the polymers. Source
