Endo-1,4-beta-xylanase

EC 3.2.1.8

Additive composition

Preparation of endo-1,4-beta-xylanase produced by Trichoderma reesei (CBS 114044) having a minimum activity of:

  • solid form: 4 × 10 6 BXU a /g

  • liquid form: 4 × 10 5 BXU/g

Characterisation of the active substance

endo-1,4-beta-xylanase produced by Trichoderma reesei (CBS 114044)

Analytical method b

In the additive and the premixture: reducing sugar assay for endo-1,4- beta-xylanase by colorimetric reaction of dinitrosalicylic acid reagent on reducing sugar yield at pH 5,3 and 50 °C

In the feedingstuffs: colorimetric method measuring water soluble dye released by the enzyme from azurine crosslinked wheat arabinoxylan substrate

Minor poultry species other than laying birds — 8 000 BXU —

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 to 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.
