Abstract:

The phytase can be used to degrade the phytate in the feedstuffs and release inorganic phosphate. It is important to increase the availability of phosphate, improve the absorption of the mineral nutrition in feedstuffs by monogastric animals and decrease the environmental phosphate pollution. The phytase can be also used as food additives, promote the absorption of minerals in human body. The phytate degradation product IP3 also has broad physiological functions in medical field. In order to embody the research significance and application value of phytase, this study reviewed phytase production from microorganism, transgenic plant and transgenic animals. The problems exited in the production of phytase were analyzed, and the prospect of phytase was also discussed.
