柠檬烯对铜绿假单胞菌的抑菌活性及其机理
Antibacterial activity and mechanism of limonene against Pseudomonas aeruginosa
摘要
Abstract
The antibacterial activity and mechanism of limonene against Pseudomonas aeruginosa were evaluated.The results showed that MIC of limonene on P.aeruginosa was 10 mL/L.Limonene inhibited the normal growth and proliferation of P.aeruginosa by measuring the bacterial growth curve.Limonene could destroy the normal morphology of cell,increase the relative conductivity of bacteria and the permeability of the cell membrane.Further,limonene reduced the membrane potential,interfered with normal metabolic activity of cell.By scanning electron microscopy,limonene destroyed cell membrane and inhibited the growth of P.aeruginosa,resulting in bacterial death.Limonene could change the permeability of the cell membrane of P.aeruginosa,destroy the normal cell morphology and integrity,thus effectively inhibit the normal growth.关键词
