A process for preserving the living bacteria contained in biologic preparation includes such steps as adding corn-starch to the fermented living bacteria contained mud, adding starch and cellulose, proportional mixing, stirring, drying, granulating, ebullience drying, and tabletting. 本发明公开了一种利用玉米淀粉保存活菌生物制剂中活菌的方法，主要是在采用现有的芽孢杆菌为菌种，经发酵后的含活菌生物制剂成品的制作过程中，加入一定的能延长活菌保存期的添加成分，其特征在于在发酵后含活菌生物制剂成品的制作过程中，向含水菌泥中加入适量的玉米淀粉，然后制成活菌生物制剂成品，上述添加玉米淀粉的方法为：取一定量发酵后并经离心脱水后的含水菌泥，加入适量的玉米淀粉，并加入适量的淀粉及纤维素，进行混合搅拌干燥、制粒、沸腾干燥、压片即成，其中菌泥的含水量为70-80％，玉米淀粉的添加量为菌泥的4-6％(重量％)，淀粉及纤维素的添加量为菌泥的80-120％和8-15％。
