英文摘要	Chemical preservatives have potential safety hazards, which may pose threats to human health. Safer biopreservatives are therefore urgently required. This study investigated the bacteriostatic activity arid mechanism of Litsea mollis Hemsl. essential oil against Escherichia coli DH5 alpha and Salmonella spp. Antibacterial activity of Litsea mollis Hemsl. essential oil 9 (LMEO9) against E. coli DH5 alpha was observed (zone of inhibition was 5.0 +/- 0.2 mm; minimum inhibitory concentration was 0.05%). Increases in electrolyte, nucleic acid, and alkaline phosphatase leakage in LMEO9-treated bacteria suggested that the cell envelope had been damaged. Scanning and transmission electron microscopy also demonstrated morphological alterations and content leakage during LMEO9 treatment. According to the kill-time analysis arid propidium iodide uptake assay, LMEO9 led to cell death. These results demonstrated that LMEO9, which could affect bacterial cell envelope structural integrity, is a low-cost biopreservative that could be useful for the dairy industry and in fresh storage.
