Xylanase
One.Product presentation
The variant strain of Aspergi Lus Clavatus is deeply fermented and cultivated,and then they are dried with low temperature to appear a kind of new enzyme—Xylanase.It can dissolve hemicellulose,xylan which is made up of Pentose to Pentose,such as xylose,glucoxylose,little gum sugar,etc.
Two.Product specification
Enzyme activity:20000-100000 u/g Package:1000g/bag
Three.Qanlity standard
Item Index Item Index
Appearance Light brown or light yellow powder Temperature 40-55℃
Proportion <1.6 The best temperature 50℃
Smell No bad smell Water content <10%
PH range 4.0-10 Content of cellulose (CMC) Less than xylanase 0.5
The best PH 5.0-6.0
Zn,Ca,Na can activate the Xylanase in some density range,and Co,Cu can control Xylanase.When the density is 10mmol/l,Xylase,Galactose,Glucose,Gum sugar,Glutamic acid,Sucrose can inrease the enzyme activity by 21 percent,especially Sucrose.
Four.Operating standard
This product accords with the sandard of Q/CBEF03-1999.
Five.Define of enzyme activity
In the condition of 50 centi degree and PH4.8,keeping temperature 30 mins,amount of Xylanase it needs can be define as one unit of activity(u mol/min) that hydrolyzing 1percent of xylan can generate 1u mol Xylose.
Six.Using condition
Temperature range:40-55 centi grade,the best temperature:48-52 centi grade;PH range:4.0-10;the best PH:5.0-6.5.
