摘要: 报道了不同浓度的柞蚕抗菌肽对大肠杆菌K12D31的杀灭作用.当浓度在2%以上时,杀菌速度大于细菌的增殖速度,通过蚕抗菌肽对大肠杆菌作用的电镜照片,及与山梨酸钾进行初步比较,证明抗菌肽的防腐机理为杀灭细菌。

Abstract: The inihibition of E. coli Ki2 D31 by cecropins from Antheraea pernyi. were studied at different concentrations. when the cecropins’ concentration is above 2 %, the velocity of inhibiion was higher than that of proliferation of bacteria. The electron microscopicphoto of the effect on E. coli K12D31 by cecropins from Antheraea pernyi is shown. The effect by cecropins from Antkeraea pernyi and potassium Sorbate are compared. The results indicate that the preservative mechanism is bactericidal effect.
