<div align="center"><strong>Acid Cellulase for Bio-polishing </strong><strong>(</strong><strong>Concentration</strong><strong>)</strong><strong></strong></div>
<div><strong></strong> </div>
<div><strong>INTRODUCTION:</strong></div>
<div> 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. <strong>SUKACell-CONC</strong> 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.</div>
<div><strong>WORKING MECHANISM:</strong></div>
<div>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.</div>
<div>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.</div>
<div><strong>PROPERTIES:</strong></div>
<div align="left"><strong>SUKACell-CONC</strong> will function from a pH of 4.5 to 6.0 with   pH 4.8 as an optimum. It will function from 40℃ to 60℃ with temperature of 55℃   as an optimum.</div>
<div align="left">Appearance: Amber liquid (Note that color does not affect or   reflect activity.) </div>
<div align="left">Odor: Slight fermentation odor</div>
<div align="left">pH (as is):4.5±1.0;</div>
<div align="left">Density:1.05-1.20</div>
<div><strong>ADVANTAGE:</strong></div>
<div><strong>SUKACell-CONC </strong>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. <strong></strong></div>

<div><strong>ENZYME ACTIVITY UNIT DEFINITION:</strong></div>
<div><strong>Reducing sugar method</strong>: At a pH of 4. 8 and temperature of 50 ℃, 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. </div>
