Method for preventing and treating postharvest diseases of fruits by lactic acid bacteria

The invention belongs to the technical field of biology, and particularly relates to a method for preventing and treating fruit postharvest diseases through lactic acid bacteria, the method comprises the steps that a microbial agent, the microbial agent contains a cross-linked body solution of the lactic acid bacteria and sodium alginate, the sodium alginate in the microbial agent and the cross-linked body solution are mixed, the mixture is sprayed to the surfaces of postharvest fruits within 10 min, and normal-temperature standing and drying are conducted. According to the method for preventing and treating the postharvest diseases of the fruits through the lactic acid bacteria, leuconostoc mesenteroides is fixed, the preservation time of the fruits is prolonged, mold breeding is inhibited, and the occurrence of the fruit diseases is effectively reduced. 本发明属于生物技术领域，具体涉及一种乳酸菌防治水果采后病害的方法，包括菌剂，该菌剂含乳酸菌的交联体溶液和海藻酸钠，将菌剂中的海藻酸钠与交联体溶液混合，在10min内喷洒于采后水果表面，常温静置干燥即可。本发明的乳酸菌防治水果采后病害的方法，对肠膜明串珠菌进行固定，延长水果保存时间，抑制霉菌滋生，有效减少水果病害
