Abstract

Carvacrol, (+)-carvone, thymol, and trans -cinnamaldehyde were tested for their inhibitory activity against Escherichia coli O157:H7 and Salmonella typhimurium . In addition, their toxicity to Photobacterium leiognathi was determined, utilizing a bioluminescence assay. Their effects on the cell surface were investigated by measuring the uptake of 1- N -phenylnaphthylamine (NPN), by measuring their sensitization of bacterial suspensions toward detergents and lysozyme, and by analyzing material released from cells upon treatment by these agents. Carvacrol, thymol, and trans -cinnamaldehyde inhibited E. coli and S. typhimurium at 1−3 mM, whereas (+)-carvone was less inhibitory. trans -Cinnamaldehyde was the most inhibitory component toward P. leiognathi . Carvacrol and thymol disintegrated the outer membrane and released outer membrane-associated material from the cells to the external medium; such release by (+)-carvone or trans -cinnamaldehyde was negligible. Of the tested components, carvacrol and thymol decreased the intracellular ATP pool of E. coli and also inreased extracellular ATP, indicating disruptive action on the cytoplasmic membrane. Keywords: Essential oils; carvacrol; carvone; cinnamaldehyde; thymol; antimicrobial activity; outer membrane; lipopolysaccharide

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
