WORK MECHANISM

Cellulose is a high-polysaccharides made of glucopyranose by β-1, 4-glycosidic bond. Cellulase system consists of three major components: Endoglucanases (endo-1, 4-β-D-glucanases; C1; EG, EC 3.2.1.4), cellobiohydrolases (exo-1, 4-β-D-glucanases; CX; CBH, EC 3.2.1.91), and β-glucosidases (1, 4-β-D-glucosidase; βG; BGL, EC 3.2.1.21). EG acts on insoluble cellulose surface, breaks internal bonds to disrupt the crystalline structure of cellulose and expose individual cellulose polysaccharide chains, and makes cellulose chains hydration easily. CBH cleaves 2-4 units from the ends of the exposed chains produced by EG, resulting in the tetrasaccharides or disaccharide such as cellobiose. There are two main types of CBH- one type working processively from the reducing end, and the other type working processively from the non-reducing end of cellulose. βG hydrolyses the CBH product into individual monosaccharides. Through the synergistic action of above enzyme system, cellulose can be efficiently hydrolyzed to glucose.

UNIT DEFINITION

One unit of cellulase is defined as the amount of enzyme which liberates 1μmol of reducing sugar from 4.0mmol/L sodium carbixymethyl cellulose substrate at 37°C and pH5.5 in one minute.

USAGE METHOD

High-quality Acid Cellulase can improve the appearance, quality, breathability, drapability and smoothness of textile. Improving the finish, sheen, flexibility, air-permeability, insulation and softness of the textile fabrics, developing permanent resistance of fabric to lint, fuzz and pill buildups and easing further treatments and dye processes.
Recommended dosage: 0.05-0.1%.

STORAGE

Stored in a cool dry place and avoid direct sunlight. Avoid to be exposed to the sun, rain, high temperature and high humidity.

ATTENTIONS

Middle temperature is non-toxic and biodegradable.
Avoid unnecessary contact and long-time exposure will make someone sensitive to this products.
Wash hands with warm soapy water after contact the product.
Keep them in the place that out of reach of children.
