- endo-1,4-beta-xylanase 1500 U/g,
- subtilisin 20000 U/g,
- alpha-amylase 2000 U/g.
- Characterisation of the active substanceEndo-1,4-beta-xylanase produced by Trichoderma reesei (ATCC PTA 5588), alpha-amylase produced by Bacillus amyloliquefaciens (ATCC 3978) and subtilisin produced by Bacillus subtilis (ATCC 2107).
- Analytical methodsDetermination of the active substance in the additive, premixtures and feedingstuffs.
- Endo-1,4-beta-xylanase: colorimetric method based on the quantification of water soluble dyed fragments produced by the action of endo-1,4-beta-xylanase on commercially available azurine cross-linked wheat arabinoxylan substances.
- Alpha-amylase: colorimetric method based on the quantification of water soluble dyed fragments produced by the action of alpha-amylase on commercially available azurine cross-linked starch polymer substances.
- Subtilisin: colorimetric method based on the quantification of water soluble dyed fragments (azurine) produced by the action of subtilisin on commercially available cross-linked casein substances.
