SUKACell-L***0
Acid Cellulase for
Bio-polishing
INTRODUCTION:
Cellulose is an unbranched glucose polymer
composed of anhydro-D-glucose units linked by 1, *-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.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.SUKACell-L***0
WORKING
MECHANISM:
The 1, *-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.
