Abstract
Abstract Marounek M., Putthana V., Benada O., Lukesova D. (2012): Antimicrobial activities of medium-chain fatty acids and monoacylglycerols on Cronobacter sakazakii DBM 3157 T and Cronobacter malonaticus DBM 3148 . Czech J. Food Sci., 30 : 573–580. Cronobacter sakazakii and Cronobacter malonaticus are pathogens causing infections in children that are primarily linked to the consumption of contaminated infant milk formula and food. Both Cronobacter strains examined were susceptible to caprylic acid, monocaprylin and, to a lesser extent, sorbic acid. Capric acid, lauric acid, monosorbin, monocaprin, monolaurin, and sucrose caprate exhibited no inhibitory activity. Caprylic acid and monocaprylin treat -ment (2 mg/ml) of C. sakazakii DBM 3157 T reduced the number of viable cells by five orders of magnitude. In the case of C. malonaticus DBM 3148, both caprylic acid and monocaprylin (2 mg/ml) decreased the viable cell counts below the limits of detection. The bactericidal activity of monocaprylin increased as a function of concentration (0.5–2.0 mg/ml) and temperature (40–55°C). The exposure of each
