Research Progress on Phytase

Phytase are enzymes capable of hydrolyzing phytic acid to less-phosphorylated myo-inositol derivates and inorganic phosphate. The addition of phytase to feed can resolve the antinutrition of phytic and increase the bioavailablity of protein and minerals. It also can dispel the pollution of phosphorus in animal wastes. This paper summarized the research progress of phytase from aspects such as the source of phytase, zymetology nature, genetic engineerings, and discussed the problem and the prospect of phytase.
