Specification :

Product name:Alpha-Amylase
Size: s41
Brief introduction:
Alpha-Amylase is made of Bacillus Subtilis in the Fermentation and extraction meth-od, is widely used in the liquefaction of starch sugar, alcohol, beer, monosodium gl-utamate, Fermentation industries and textile, printing & dyeing, desizing etc..
Characteristics:
(1) heat stability:Stable in 60 oC or below, Best operational temperature 60 -70 oC, applicable to the liquefaction process of 90oC(highest).
(2)PH Stability: PH6.0-7.0 more stable; optimum operation is under PH6.0; In PH5.0, inactivation is serious.
(3) Calcium ion affects the active stability of enzyme : Calcium ion can improve the stability of enzyme activity, it will be in active when there are no Calcium ion.
Properties:
