Preservative Mechanism of Cecropins From antheraea Pernyi

Abstract

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.

Key words: , Antheraea Pernyi Cecropins E.coli K12D31 Potassium Sorbate Preservative Mechanism；
