Endo-1,4-beta-xylanase (EC 3.2.1.8) |
Additive composition Preparation of endo-1,4-beta-xylanase (EC 3.2.1.8) produced by Komagataella phaffii DSM 33574 with a minimum activity of: 150 000 XU(1)/g Solid form Characterisation of the active substance Endo-1,4-beta-xylanase (EC 3.2.1.8) produced by Komagataella phaffii (DSM 33574) Analytical method (2) For the determination of endo-1,4-beta-xylanase activity in the feed additive: colorimetric (DNS) method based on the enzymatic hydrolysis of the beechwood xylan substrate. For the determination of endo-1,4-beta-xylanase activity in compound feed: colorimetric method based on the enzymatic reaction of endo-1,4-beta-xylanase on the Xy1X6 substrate. |
All poultry species for fattening All poultry species reared for laying or reared for breeding purposes |
