General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency and waste prevention when used in cellulosic ethanol research. For more information see the article in biofiles.

β -Glucanase represents a group of carbohydrate enzymes which break down glycosidic bonds within beta-glucan. It forms the main constituent of fungal cell walls and could be a potential structural and storage polysaccharide of marine macro-algae. It has the ability to degrade fungal cell walls and may be involved in defense mechanism of plants against pathogenic fungi.


β -Glucanase was used as a cellulase enzyme in the combined biological and chemical pretreatment method for lignocellulosic ethanol production from energy cane. It was also used in the enzymatic saccharification of cellulose and production of ethanol.


100 g in poly bottle
