Allgemeine Beschreibung

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, which is secreted by various cellulolytic microorganisms.

Anwendung

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.
The enzyme has also been approved as a secondary direct food additive as an aid in clam and shrimp processing.

Biochem./physiol. Wirkung

Cellulase aus Aspergillus niger katalysiert die Hydrolyse von Endo-1,4-β-D-glycosidischen Verbindungen in Zellulose, Lizenin, Gerstenglucan und die Cellooligosacchariden-Cellotriose zu Cellohexaose. Bewirkt keine Spaltung von Cellobiose oder p-Nitrophenyl-β-D-glucosid. Dieses Enzym spaltet auch intaktes Glykosaminoglykan aus einem Kernpeptid durch Hydrolyse der Xylosylserin-Verbindung.

Einheitendefinition

1 U setzt 1.0 μmol Glucose aus Cellulose pro Stunde frei bei pH 5.0 und 37 °C (2 Std Inkubationszeit).

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
