Anti listeria effects of Echinophora platyloba DC. extracts in broth medium and milk

Listeria monocytogenes is known as one of the bacteria transmitted by food, especially dairy products. Recently, the demand for replacing chemical preservatives with natural compounds has increased. The aim of this study was to investigate the antibacterial effects of Echinophora platyloba DC. extracts on Listeria monocytogenes in broth medium and milk. The standard method of microdilution was used to determine the minimum inhibitory concentration and the minimum bactericidal concentration of aqueous and ethanol extracts of Echinophora platyloba on tested bacteria. The results showed that the minimum inhibitory concentrations of aqueous and ethanol extracts, were 50 and 70 mg/ml respectively and the minimum bactericidal concentrations for these extracts, were 70 and 100 mg/ml respectively. Based on the results, both aqueous and ethanol extracts showed acceptable anti listeria effects at 4ºC and 25ºC in milk compared to the control group (P
