植酸酶是采用黑曲霉（Aspergillus niger）经液体深层发酵、超滤等工序精制而成。植酸酶能将植酸磷降解成肌醇和磷酸，作为环境友好型的酶制剂在减少磷的使用量中具有重要意义。

Phytase is refined from Aspergillus niger by submerged fermentation and ultrafiltration. Phytase can degrade phytate phosphorus to inositol and phosphoric acid, so it is very important to reduce the use of phosphorus as an environmentally friendly enzyme.
