Application

Cellulases are enzymes that hydrolyze cellulose to glucose. Cellulase is used to study the development of occupational asthma in the detergent, pharmaceutical, baking, and enzyme production industries . Cellulase is added to detergents to improve cleansing properties . Cellulase, product C9499, is from Clostridium thermocellum and is recombinant and expressed in E. coli.

Biochem/physiol Actions

Cellulases are produced by the intestinal flagellates of termites which are important for cellulose digestion of their host termites . Cellulases have different microbial origins and therefore different protein sequences . Product C9499 exhibits endo-cellulase, β-glucanase activity when assayed using insoluble AZCL-linked substrates as well as exo-cellulase and cellobiohydralase activities.

Physical form

Supplied as as solution in 50 mM Tris-HCl, pH 7.5, 100 mM NaCl, and 25% glycerol.

Other Notes

One unit will produce 1 μmole of reducing sugar (measured as glucose) from β-glucan per minute at pH 5.8 at 70 °C.

The intestinal flagellates of termites produce cellulases that contribute to cellulose digestion of their host termites. However, 75% of all termite species do not harbour the cellulolytic flagellates; the endogenous cellulase secreted from the midgut tissue has been considered a

Three employees from two different detergent companies were investigated for occupational asthma, using skin prick tests, serum specific IgE, and specific bronchial challenge. Two were challenged with lipase and one with cellulase. All three cases had immunological evidence of sensitisation

Several aminopeptidases of the M42 family have been described as tetrahedral-shaped dodecameric (TET) aminopeptidases. A current hypothesis suggests that these enzymes are involved, along with the tricorn peptidase, in degrading peptides produced by the proteasome. Yet the M42 family remains

To screen, identify bacterial strains with high capability to degrade cellulose from bacteria associated with Bursaphelenchus xylophilus and to clone related genes. First, we collected B. xylophilus samples from pine wood nematode disease areas in Nanyang, Henan province, China. Then

The aim of this study was to screen microorganisms that could degrade rice straw. We used selective medium to screen strains and determined straw fracture tension strength, weight loss, lignocellulose decomposition rate and extracellular enzyme activity as re-screening methods after
