Abstract
The objective of this study was to assess the antimicrobial activity of salts of phenolic acids against Yersinia enterocolitica ATCC 23715. Y. enterocolitica is known to be a facultatively anaerobic, Gramnegative coccoid bacillus responsible for human alimentary intoxication. Salts of phenolic acids can effectively eliminate pathogens in food products. It was proved that the salts of phenolic acids inhibited the growth of this pathogen. The analysis comprised the lithium, sodium, and potassium salts of the o-coumaric, m-coumaric, and p-coumaric acids. Water solutions of those salts were applied; their concentrations were 1 %, 2 %, 3 %, 4 %, and 5 %. A diffusion-well method was used. The analysis results showed that Y. enterocolitica was susceptible to the salts of o-coumaric and m-coumaric acids, however, its susceptibility to the salts of p-coumaric acid was not confirmed. The salts of phenolic acids can be applied as natural chemical preservatives in food conservation processes.
