本文通过改变培养基的种类、培养基的碳源、氮源、无机盐离子来选择絮凝剂产生菌“Dfjm-1”高效低廉的培养基；通过改变培养基初始pH值、培养温度、培养过程中的通气量等因素，得出“Dfjm-1”菌株产生絮凝剂的最佳条件。Dfjm-1产生絮凝剂的最佳因素为：培养基初始pH值为6.5～7.0，培养温度为30℃，培养时间为60小时左右，通气量为：早期：250r/min；中期150r/min；后期100～150r/min。

In this paper,the high production rate and low cost Dfjm-1 medium was obtained by selecting diffe-rent kinds of media,carbon source,nitrogen source and inorganic salt ion.The best flocculant-producing conditions were found by changing medium initial pH,culture temperature and ventilation flow.The optimum culture conditions are:pH 6.5～7.0,culture temperature 30℃,60 hours for cultivation.
