Endo-1,3(4)-beta-glucanase
EC 3.2.1.6
Additive composition
Preparation of endo-1,3(4)-beta-glucanase produced by Trichoderma reesei (CBS 126896) having a minimum activity of:
—
solid form: endo-1,3(4)-beta-glucanase 200 000 BU ( 1 ) /g,
—
liquid form: endo-1,3(4)-beta-glucanase 400 000 BU/ml.
Characterisation of the active substance
endo-1,3(4)-beta-glucanase produced by Trichoderma reesei (CBS 126896)
Analytical method
( 2 )
For the quantification of endo-1,3(4)-beta-glucanase activity: spectrophotometric (DNS) method, based on the quantification of released sugars produced by the action of endo-1,3(4)-beta-glucanase on barley beta-glucan at pH 4,8 and 50 °C.
