SUKACell-CONC

Acid Cellulase for Bio-polishing (Concentration)

INTRODUCTION

 Cellulose is an unbranched glucose polymer composed of anhydro-D-glucose units linked by 1, 4-b-D-glucoside bonds. These glycosidic bonds can be hydrolysed by cellulolytic enzymes. The native structure of the cellulose is composed of crystalline and less organized amorphous regions. SUKACell-CONC is an enzyme preparation obtained from the submerged fermentation of a high cellulase-producing microbial strain. It is widely used in textile and garment stone wash industries.

WORKING MECHANISM

The 1, 4-b-D-glucosidic linkages in cellulose, lichenin and cereal b-D glucans are hydrolyzed to release free glucose units through the successive action of cellulase enzymes.

The less organized amorphous region at the center of the cellulose chain is initially attacked by endoglucanase by random cutting of the b-1, 4 glycosidic linkages within the chain thereby producing cello-oligosaccharides. Cellobiohydrolases I and II act on the cello-oligosaccharides from the reducing end and non-reducing end of the cello-oligosaccharides to release cellobiose. b- glucosidase act on the released cellobiose to produce b–D glucose units.

PROPERTIES

SUKACell-CONC will function from a pH of 4.5 to 6.0 with pH 4.8 as an optimum. It will function from 40°C to 60°C with temperature of 55°C as an optimum.

Appearance  Amber liquid (Note that color does not affect or reflect activity.)

Odor Slight fermentation odor

pH (as is) 4.5±1.0

Density 1.05-1.20

ADVANTAGE

SUKACell-CONC can obviously improve the effect of biofinishing for 100% cotton fabrics, cotton, terylen mixture fabric, both woven and knits, jeans, significantly reduce cottony ball, soften the fabrics and bright the color. Cloth draping property and water absorption are greatly improved. After treatment, jeans feature of clear texture, soft character and old sense. Reduce the dosage of pumice to wash jeans, reducing equipment abrasion and difficulty for wastewater treatment.

This product is concentrated product-dilute to use, economical and practical.

High activity product is available upon request of customers.

ENZYME ACTIVITY UNIT DEFINITION

Reducing sugar method At a pH of 4. 8 and temperature of 50 °C, to produce the amount of reducing sugar equivalent to 1 mg glucose, it needs l g solid enzyme (or 1mL liquid enzyme) and 1 h hydrolyze sodium carboxymethyl cellulose substrate, as 1 enzyme activity unit, state as u/g (or u/mL). CMCA – DNS for short.

NOTE Some denim fabrics of lower quality may have severe backstaining problems that can be overcome with our ES resist.

Use soda ash 1-3 grams and resist ES 1-2 grams (water ratio) to wash out ferment remaining residue, after that adopt our consistent lubricant/ film/ organic silicon oil.

PACKAGING

SUKACell-CONC is packaged in 25 kg plastic drum.

Alternative packaging is available upon request for smaller or larger volumes. 

STORAGE

 Store in a cool, dry place and away from direct sunlight. SUKACell-CONC maintains its activity for considerably longer time when stored at lower temperatures (below 20°C). Do not let freeze.

HANDLING PRECAUTIONS

SUKACell-CONC is non-toxic and biodegradable. However, unnecessary contact with the product should be avoided. Long term exposure to protein based products such as SUKACell-CONC may sensitize certain individuals to the product. Wash hands with warm soapy water after handling. Keep out of reach of children.
