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 and Enzymes for Alternative Energy Research.

Cellulase from Trichoderma reesei is produced by submerged fermentation of a selected strain of the fungus Trichoderma reesei and catalyzes the breakdown of cellulose into glucose, cellobiose, and higher glucose polymers. It corresponds to a molecular mass of 68 kDa with optimum pH and temperature of 6 and 52° C, respectively.


Cellulase from Trichoderma reesei has been used:
  • for aqueous extraction of oil from corn germ
  • in the enzymatic hydrolysis of Sweet Sorghum Bagasse (SSB)
  • in the enzymatic digestion of paper grids
Cellulase from Sigma has been used to degrade cello-oligosaccharides into glucose in order to investigate the biodegradability of bioabsorbable bacterial cellulose (BBC).

Biochem/physiol Actions

Cellulase complexes with β-glucosidase for degrading cellobiose to glucose polymer. The lignin content in straw and furfural residues hampers cellulase production.
