IMI CC 378536 and Talaromyces versatilis sp. nov. DSM 26702 having a minimum activity of:- solid form: endo-1,4-beta-xylanase 22000 VU/g and endo-1,3(4)-beta-glucanase 15200 VU/g,
- liquid form: endo-1,4-beta-xylanase activity of 5500 VU/ml and endo-1,3(4)-beta-glucanase 3800 VU/ml.
Characterisation of the active substanceEndo-1,4-beta-xylanase (EC 3.2.1.8) and endo-1,3(4)-beta-glucanase (EC 3.2.1.6) produced by Talaromyces versatilis sp. nov. IMI CC 378536 and Talaromyces versatilis sp. nov. DSM 26702.Analytical methodFor the quantification of endo-1,4-beta-xylanase activity:- viscosimetric method based on decrease in viscosity produced by action of endo-1,4-beta-xylanase on the xylan containing substrate (wheat arabinoxylan).
For the quantification of endo-1,3(4)-beta-glucanase activity:- viscosimetric method based on decrease in viscosity produced by action of endo-1,3(4)-beta-glucanase on the glucan substrate barley betaglucan at pH = 5,5 and 30 °C.
