摘要
Abstract
The adults of Tenebrio molitor were extracted with ethyl acetate,and then the resulting crude extract was separated by silica gel column chromatography to obtain lipid antibiotic substances in the ethanol eluate.The inhibitory effect of the antibiotic substances gainst bacteria and fungi was also investigated.The results showed that the lipid antibiotic substances with and without heating in 100 ℃ water bath for 20 min had a significant inhibitory effect on G-bacteria,suggesting their good thermal stability.The lipid antibiotic substances also had a significant inhibitory effect on three species of pathogenical fungi.When the concentration was 50 mg/mL,the decay rates of apples and pears were reduced by 13.24% and 16.90%,respectively.The lipid antibiotic substances also could prolong the shelf life time of bean curd.关键词
