【摘要】 报道了采用凝聚和絮凝的技术进行微生物菌体的收集方法。无机凝聚剂氯化钙和高分子絮凝剂壳聚糖分别对富含延胡索酸酶的产氨短杆菌MA - 2、黄色短杆菌MA - 3进行凝聚和絮凝实验 ,两菌酶活回收率达95 9%～ 98 7%更多还原

【Abstract】 A new method of collecting microbial cells by flocculating and coagulating reagents was studied. The fumarase producing cells such as B.ammoniagenes MA-2 and B. flavum MA-3 were treated with inorganic coagulating reagent calcium chloride and high polymeric flocculating reagent chitosan respectively, and the recovery of the enzyme activity reached 95 9%～98 7%.更多还原
