植酸酶可以分解动物饲料中 的植酸磷,释放出动物能够直接利 用的磷。在饲料中添加少量植酸酶 可以代替大量价格昂贵的无机磷 酸钙的添加,使饲料成本降低,饲 料综合利用率提高;此外还可减少 磷对土壤和环境的污染。目前我国 该产品主要靠进口,因价格较昂 贵,影响了其在饲料中的广泛应 用。四川农业大学王红宁教授主持 的国家“八五”、“九五”重点科技攻 关项目子课题对植酸酶基因工程 Phytase breaks down phytate phosphorus in animal feed and releases phosphorus that animals can use directly. Adding a small amount of phytase to feed can replace a large amount of expensive inorganic calcium phosphate, resulting in lower feed costs and improved feed comprehensive utilization. In addition, phosphorus can reduce the pollution of soil and the environment. At present, China mainly relies on imports of the product, because of the price is more expensive, affecting its extensive use in feed. Sichuan Agricultural University Professor Wang Hongning presided over the national “85”, “95” key scientific and technological project sub-topics of phytase gene engineering
