用于饲料生产的植酸酶产生菌的筛选

Survey of the Selection for the Production of Phytase Used in Feedstuff

筛选分离出多株植酸酶产生菌，并就其中四株菌利用固态发酵培养，考察其在不同时间的产酶情况，以及在不同ｐＨ条件下的酶活表现，为其用于饲料生产提供依据。

Some strains producing phytase were selected.Using solid state fermentation process, phytase produced in different time and the enzyme activities in different pH were observed. All these provided evidences for the feedstuff production.
