Fig. 7From: The antimicrobial effect of a novel peptide LL-1 on Escherichia coli by increasing membrane permeabilityEffect of LL-1 on E.coli observed by transmission electron microscopy. a PBS-treated E.coli observed by transmission electron microscopy. b 2 MIC LL-1-treated E.coli observed by transmission electron microscopy. Black arrows pointed to dead bacteria. c PBS-treated E.coli observed by transmission electron microscopy. d 2 MIC LL-1-treated E.coli observed by transmission electron microscopy. Bacterial plasmolysis occurred at the site indicated by the black arrow. Bacterial membrane lysis occurred at the site indicated by the white arrowBack to article page
