Functional group: digestibility enhancers. 4a1601 Andrés Pintaluba S.A. Endo-1,3(4)-beta-glucanase EC 3.2.1.6 and 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 1 100 U ( 1 ) /g and endo-1,4-beta-xylanase 1 600 U ( 2 ) /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 method ( 3 ) For 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. Chickens for fattening Laying hens Pigs for fattening Minor poultry species Minor porcine species for fattening — Endo-1,3(4)-beta-glucanase 138 U Endo-1,4-beta-xylanase 200 U — 1. In the directions for use of the additive and premixtures, the storage conditions and stability to heat treatment shall be indicated. 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. 7.11.2027 ( 1 ) 1 U (unit) endo-1,3(4)-beta-glucanase is the amount of enzyme which liberates 1 μmole of reducing sugar (glucose equivalents) from oat beta-glucan per minute at 30 °C and pH 4. ( 2 ) 1 U (unit) endo-1,4-beta-xylanase is the amount of enzyme which liberates 1 μmole of reducing sugar (xylose equivalents) from oat xylan per minute at 30 °C and pH 4.
