【摘要】：植酸酶對于有效釋放飼料中的植酸磷有著重要的意義,目前國內(nèi)外對植酸酶的研究已經(jīng)從基礎(chǔ)的理論研究向應(yīng)用研究發(fā)展,從天然獲取向基因工程發(fā)展,通過對目前市面上銷售的6個品牌的耐高溫植酸酶進行實驗室濕熱試驗和飼料制粒試驗,研究這6個經(jīng)過高溫處理后植酸酶的濕熱酶活存留率和制粒酶活存留率。結(jié)果表明:國外品牌F耐溫效果最優(yōu),國內(nèi)品牌A可與之媲美,85℃飼料制粒仍可保留85.92%,顯著高于除國外品牌F的其他各品牌植酸酶;另外,實驗室濕熱法對于飼料實際制粒耐熱結(jié)果具有一定指導意義。
[Abstract]:Phytase is of great significance for the effective release of phytase from feed. At present, the research on phytase has been developed from basic theory to application, from natural acquisition to genetic engineering. Through the laboratory hygrothermal test and pelletizing test of 6 brands of heat-resistant phytase, which are currently available on the market, The retention rate of wet-heat enzyme activity and granulase activity of the six phytase treated at high temperature were studied. The results showed that foreign brands F had the best effect on temperature tolerance. Domestic brand A can still keep 85.92% of feed granulation at 85 鈩，
