Endo-1,4-beta-xylanase
(EC 3.2.1.8)
Additive composition
Preparation of endo-1,4-beta-xylanase produced with Trichoderma reesei CBS 114044 having a minimum activity of:
Solid form: 160 000 BXU ( 1 ) /g
Liquid form: 160 000 BXU/g
Characterisation of the active substance
Endo-1,4-beta-xylanase (EC 3.2.1.8) produced with Trichoderma reesei CBS 114044
Analytical method
( 2 )
For the quantification of endo-1,4-beta-xylanase in the feed additive and premixtures:
—
colorimetric method based on the enzymatic reaction of endo-1,4-beta-xylanase on the birch xylan substrate at pH 5,3 and 50 o C
For the quantification of endo-1,4-beta-xylanase in compound feed:
—
colorimetric method based the enzymatic reaction of endo-1,4-beta-xylanase on the azurine cross-linked wheat arabinoxylan substrate at pH 5,3 and 50 o C
Pigs for fattening

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 the potential risks resulting from their use. Where those risks cannot be eliminated by such procedures and measures, the additive and premixtures shall be used with personal protective equipment, including breathing, skin and eye protection for solid forms, and breathing protection for liquid forms.
