Nutrizyme®PHY (phytase) [EC 3.1.3.26] is a
thermostable preparation produced by submerged fermentation of Aspergillus
niger followed by purification and formulation. It breaks down the
undigestible phytic acid (phytate) found in grains and oil seeds and thus
release digestible phosphorus, calcium and other nutrients. The
thermostability, wide working pH range and the resistance to proteolysis of the
product ensure its excellent performance. The even granulation and appropriate
granulate size of the product make it easy to blend with feed well.
As an animal feed additive often used in poultry and
swine feed, it enhances the nutritive value of plant material in feed by
liberation of inorganic phosphate from phytic acid (myo-inositol
hexakisphosphate), thereby, reduce environmental phosphorus pollution. 3
products with different enzyme activity are available for their applications in
different cases.
