Study on the membrane action mechanism of EGCG against Aeromona hydrophila
摘要
Abstract
Antimicrobial effect of EGCG against Gram-negative Aeromonas hydrophila was investigated. As a result, minimal inhibitory concentration(MIC) of EGCG against Aeromonas hydrophila was 25~5Oμg/mlThe mechanism of action was further investigated by cell integrity and membrane permeabilization assays. The assay showed that EGCG obviously increased the membrane permeability, and induced the leakage of ion and macromolecules in the cytoplasm. Flow cytometric analysis revealed that EGCG can cause significant membrane damage for influx of ONPG into cells. Results indicated that EGCG killed Aeromonas hydrophila by disrupting the structure of cell membranes and caused the leakage of intracellular components from bacterial cells.关键词
