AIMS Compare the survival behaviour of food spoilage micro-organisms treated with sequential doses or all at once treatments of eugenol. METHODS AND RESULTS Staphylococcus carnosus, Listeria innocua, Escherichia coli and Pseudomonas fluorescens were exposed to a minimal lethal concentration (MLC) initially, or to half doses over time, with first half dose(More)
The effectiveness of sequential applications of the antimicrobials eugenol and lauric arginate (LAE) was investigated against Staphylococcus carnosus, Listeria innocua, Escherichia coli K12, and Pseudomonas fluorescens. The antimicrobials were applied simultaneously at half of their minimum lethal concentrations (MLC) or sequentially at t = 0 h and t = 3,(More)
Effects of a sequential application of eugenol and temperature on the survival of two model spoilage organisms, Staphylococcus carnosus LTH1502 and Escherichia coli K12 C600, were studied. To assess effects of a "temperature first-antimicrobial later" treatment, cultures were treated with eugenol at 20, 37 and 42 °C at the beginning of the incubation(More)
