4a1601 | Andrés Pintaluba S.A. | Endo-1,3(4)-beta-glucanase EC 3.2.1.6and endo-1,4-beta-xylanase EC 3.2.1.8 | Additive composition:Preparation of endo-1,3(4)-beta-glucanase (EC 3.2.1.6) and endo-1,4-beta-xylanase (EC 3.2.1.8) produced by Aspergillus niger (NRRL 25541) having a minimum activity of: endo-1,3(4)-beta-glucanase 1100 U/g and endo-1,4-beta-xylanase 1600 U/g.(solid form)Characterisation of the active substance:Endo-1,3(4)-beta-glucanase (EC 3.2.1.6) and endo-1,4-beta-xylanase (EC 3.2.1.8) produced by Aspergillus niger (NRRL 25541).Analytical methodFor the characterisation in the feed additive and premixtures of:- endo-1,3(4)-beta-glucanase activity: colorimetric method measuring reducing sugar (glucose equivalents) released by the action of endo-1,3(4)-beta-glucanase on barley beta-glucan substrate in presence of 3,5-dinitrosalicil acid (DNS);
- endo-1,4-beta-xylanase activity: colorimetric method measuring reducing sugar (glucose equivalents) released by the action of endo-1,4-beta-xylanase on oat xylan substrate in presence of 3,5-dinitrosalicil acid (DNS).
For the characterisation in the feed of:- endo-1,3(4)-beta-glucanase activity: colorimetric method measuring depolymerised soluble fragments released by the action of endo-1,3(4)-beta-glucanase on azo-barley-glucan;
- endo-1,4-beta-xylanase activity: colorimetric method measuring depolymerised soluble fragments released by the action of endo-1,4-beta-xylanase on azo-xylan.

- 2.For users of the additive and premixtures, feed business operators shall establish operational procedures and organisational measures to address potential risks resulting from their use. Where those risks cannot be eliminated or reduced to a minimum by such procedures and measures, the additive and premixtures shall be used with personal protective equipment, including skin, eyes and breathing protections.
