Characterisation of the active substance

6-phytase (EC 3.1.3.26) produced by fermentation with Komagataella phaffii CGMCC 12056

Analytical method4

For the quantification of phytase activity in the feed additive:

  • colorimetric method based on the enzymatic reaction of phytase on the phytate – VDLUFA 27.1.4

For the quantification of phytase activity in premixtures:

  • colorimetric method based on the enzymatic reaction of phytase on the phytate -VDLUFA 27.1.3

For the quantification of phytase activity in feed materials and compound feed:

  • colorimetric method based on the enzymatic reaction of phytase on the phytate – EN ISO 30024

One unit is the amount of enzyme which releases one micromole of inorganic phosphate from phytate per minute at pH 5,5 and 37 °C.
