In order to check for morphological changes resulting from the
antimicrobial treatment, SEM was performed on bacteria exposed
to LAE at MIC concentrations. Microphotographs show that treated
bacteria displayed considerable morphological alterations in com-parison to the control bacteria (Fig. 2A). After 3 min of exposure
(Fig. 2B), the cells, exhibit external modifications as irregular shape,
significant rough surface, pore formation and cell debris. After
5 min of exposure (Fig. 2C), alterations are more noticeable and
a high number of collapsed bacteria are detected. All these alter-ations on the outer bacteria envelope may be indicate that cell
membranes are the main target of this substance
