This study was carried out to assess the antilisterial potential of ethyl acetate (EtOAc) extract of a marine isolate of Aspergillus sp. The in vitro antilisterial efficacy of ethyl acetate extract was examined using disc diffusion, minimum inhibitory concentration (MIC) determination, cell viable count and scanning electron microscopic (SEM) methods against the employed strains of Listeria monocytogenus. The ethyl acetate extract () exhibited a promising antilisterial effect as diameters of inhibition zones against L. monocytogenes ATCC 19111, 19116, 19118, 19166 and 15313, which were found in the range of 11-17 mm along with their MIC values ranging from 125 to respectively. Also the EtOAc extract had strong detrimental effect on the viable count of the tested L. monocytogens ATCC 19166. Furthermore, scanning electron microscopic (SEM) study demonstrated potential detrimental effect of ethyl acetate extract on the morphology of L. monocytogenes ATCC 19116 at the used MIC concentration. These findings strongly support the role of ethyl acetate extract of a marine isolate of Aspergillus sp. as an antiliterial potential.
