摘要
试验以豆粕粉和玉米粉为底物,研究植酸酶在不同温度、pH值条件下的生物活性。结果表明:以玉米粉为作用对象,植酸酶最适酶解pH值为4.0,最适酶解温度为33℃;以豆粕粉为作用对象,植酸酶最适酶解pH值为4.0,最适酶解温度为35℃。
In this experiment, maize powder and soybean powder used as substrates, phytase bioaetive under different temperature and pH value was researched. The result showed that： If taking maize powder as substrate,the optimum pH for enzymolysis was 4.0 and reaction temperature was 33℃; If taking soybean powder as substrate, the optimum pH for enzymolysis was 4.0 and reaction temperature was 35℃.
