SUKACell
cellulase enzyme
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.
DESCRIPTION
SUKACell is an enzyme preparation obtained from the submerged fermentation of a high cellulase-producing microbial strain. It is widely used in feed, textile, wastewater treatment and paper making industries.
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.
PROPERTIES
SUKACell provides maximal benefit at pH 4.8 – 5.2 and at the temperature of *5 – *0°C (**1 – **0°F).
SPECIFICATION
SUKACell is available in liquid preparation as:
SUKACell LQ*0 (with enzyme activity of *0,**0 U/mL)
SUKACell LQ*0 (with enzyme activity of *0,**0 U/mL)
SUKACell is available in solid preparation as:
SUKACell PW*0 (with enzyme activity of *0,**0 U/g)
SUKACell PW*0 (with enzyme activity of *0,**0 U/g)
Unit definition: The amount of enzyme needed to produce 1 mg glucose from carboxymethylcellulose (CMC) in
one hour at specified conditions by the DNS method.
APPLICATION GUIDE
l For use as a feed additive, SUKACell can be added to the mix at a rate of 0.***0.1%.
l For use in the textile industry, add SUKACell at the rate of 2.**5 g/kg of fabric dissolved as 5:1 water
: clothes ratio. The product can also be added at
***0 g/kg of fabric dissolved as *0:1 water : clothes ratio.
l For the paper making industry, SUKACell is added based on the instructions of the technicians.
PACKAGING
SUKACell is packaged in *5 kg/plastic drum and ***0 L/plastic drum for the liquid form while the solid
preparation is packaged as *0 kg per box or film lined woven bag.
Alternative packaging is available upon request for smaller or larger volumes.
STORAGE
Store in a cool, dry place and away from direct sunlight. SUKACell maintains its activity for considerably
longer time when stored at lower temperatures
(below *5°C). The product should not be frozen.
HANDLING PRECAUTIONS
SUKACell is non-toxic and biodegradable. However, unnecessary contact with the product should
be avoided. Long term exposure to protein based products such as
SUKACell may sensitize certain individuals
to the product. Wash hands with warm soapy water after handling. Keep out of reach of children.
