Cellulase from Aspergillus niger

一般描述

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.

生物活性/药理作用

Cellulase from Aspergillus niger catalyzes the hydrolysis of endo-1,4-β-D-glycosidic ages 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 age.

应 用

Cellulase 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.

有效单位定义

One unit will liberate 1.0μmole of glucose from cellulose in one hr at pH5.0 at 37°C (2 hr incubation time).
