摘要

The purpose of this study was to first evaluate the antimicrobial effects of powder and extracts of berries (rose-hip, aronia, sea buckthorn and hawthorn) on the development of antibiotic-resistant <i><span style="font-family:Verdana;">L</span></i><span style="font-family:Verdana;">. </span><i><span style="font-family:Verdana;">monocitogenes</span></i><span style="font-family:Verdana;">. </span><i><span style="font-family:Verdana;">Listeria</span></i> <i><span style="font-family:Verdana;">monocytogenes</span></i><span style="font-family:Verdana;"> is considered one of the most important pathogens responsible for food-borne infection. Antimicrobial properties were evaluated using the standard Kirby-Bauer disk diffusion method. Bacterial inactivation networks were determined and compared, as well as the possibility of using powders and extracts of berries to control the risk of </span><i><span style="font-family:Verdana;">Listeria</span></i> <i><span style="font-family:Verdana;">monocytogees</span></i><span style="font-family:Verdana;"> infestation in the milk and dairy industry as well as in the meat industry. The effect of pH (4.78 - 4.43) and water activity (0.90 - 0.80) on the relationship between optical density (OD) at 600 nm and the plate count (CFU ml^-</span><span style="font-family:Verdana;">¹</span><span style="font-family:Verdana;">) was investigated for </span><i><span style="font-family:Verdana;">Listeria</span></i> <i><span style="font-family:Verdana;">monocytogenes</span></i><span style="font-family:Verdana;">.
