摘要
灰葡萄孢菌(Botrytis cinerea)是导致果蔬腐败的主要病原菌之一.乳酸菌因为安全、无毒且具有一定的抗菌作用,在抑制果蔬腐败病原菌方面具有一定的潜在价值.鉴于此,文章期望从发酵食品和常见水果表面分离并筛选出抑制灰葡萄孢菌活性的乳酸菌,结果发现有10株乳酸菌对灰葡萄孢具有抑菌活性.经鉴定,3 株(JZ a1、MJ a2、PS b1)为 Limosilactobacillus fermentum,2 株(ZLJ、MDF b)为 Lactobacillus pentosus,MHT b 为 Lactobacillus acidophilus,4 株(SCb1、MJ a、MDF a、MHT a1)还有待进一步鉴定.文章为开发果蔬生物保鲜剂提供了实践基础与理论支撑.
Abstract
Botrytis cinerea is one of the main pathogens of fruit and vegetable spoilage.Because of its safety and non-toxicity,lactic acid bacteria have a certain antibacterial effect,which has a potential value to inhibit the pathogens of postharvest spoilage of fruits and vegetables.In view of this,this study is expected to isolate and screen out lactic acid bacteria from fermented foods and common fruits,and 10 strains were found to have antibacterial activity against Botrytis cinerea;three strains(JZ a 1,MJ a 2,PS B 1)were identified as Lactobacillus fermentum,two strains(ZLJ,MDF B)as Lactiplantibacillus pentosus,and MHTb as Lactobacillus acidophilus,four strains(SCB1,MJA,MDF A,MHTA1)need to be further identified.This study provides a practical basis and theoretical support for the development of bio-preservatives for fruits and vegetables.
