Opis ogólny
The FDA recognizes cellulase from A. niger as GRAS (Generally Regarded As Safe) if non-pathogenic and non-toxigenic strains, as well as current good manufacturing practices, are used in production.
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 used as enzyme for alternative energy. For more information see the Enzymes for Alternative Energy Research.
Cellulase belongs to the family of glycoside hydrolase,[1] which is secreted by various cellulolytic microorganisms.[2]

Zastosowanie
Cellulase from Sigma has been used to study the ability of several of its possible substrates, cellulose, Avicel PH-101, and filter paper, to protect enzyme activity during monogastric diegstion in animal and avian digestive tracts.[3]
The enzyme has also been approved as a secondary direct food additive as an aid in clam and shrimp processing.[4]
Działania biochem./fizjol.
Cellulase from Aspergillus niger catalyzes the hydrolysis of endo-1,4-β-D-glycosidic linkages in cellulose, lichenin, barley glucan, and the cellooligosaccharides cellotriose to cellohexaose. It does not cleave cellobiose or p-nitrophenyl-β-D-glucoside. This enzyme will also cleave intact glycosaminoglycan from a core peptide by hydrolyzing the xylosyl serine linkage.
Definicja jednostki
One unit will liberate 1.0 μmole of glucose from cellulose in one hr at pH 5.0 at 37 °C (2 hr incubation time).

A major challenge in converting lignocellulose to biofuel is overcoming the resistance of the biomass structure. Herein, sequential dilute acid-alkali/aqueous ammonia treatment was evaluated to enhance enzymatic hydrolysis of poplar biomass by removing hemicellulose first and then removing lignin with

The current production of bioethanol based on lignocellulosic biomass (LCB) highly depends on thermostable enzymes and extremophiles owing to less risk of contamination. Thermophilic bacterial cellulases are preferred over fungi due to their higher growth rate, presence of complex multi-enzymes

What is the solution stability of Cellulase, Product C1184?
1 answer-
Sigma-Aldrich has not determined the solution stability for this product. However, it is reported in Methods in Enzymology, 160, 264 (1988) that cellulase from Aspergillus niger is "completely stable over the range of pH 5.0-8.0 at 4°C for 24 hours and retains about 50% of its original activity after heating at 70°C for 10 minutes. The enzyme is completely inactivated by heating at 80°C for 10 minutes".

Are there any additives to Cellulase, Product C1184, in addition to the enzyme itself?
1 answer-
Per information from our supplier, maltodextrin is an extender in this product. Maltodextrin can vary in glucose chain lengths of 2-12. There can also be some free glucose in the product. Either sorbitol or propylene glycol is added to the product as a stabilizer during processing. These components may be "flashed off" during processing, but some small amount may still be present.
