Nutrizyme^®PHY-P (phytase) [EC 3.1.3.26] is a highly concentrated thermostable premium phytase 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. Compared with mainstream products, Nutrizyme®PHY-P exhibits obviously better pH tolerance and thermostability, minimizing inactivation during feed pelleting process.
