Abstract:
... To characterize the antibacterial synergy of the antimicrobial peptide, ranalexin, used in combination with the anti-staphylococcal endopeptidase, lysostaphin, against methicillin-resistant Staphylococcus aureus (MRSA), and to assess the combination's potential as a topical disinfectant or decolonizing agent for MRSA. MRSA causes potentially lethal infections, and pre-operative patients colonized ...

Escherichia coli; Lactobacillus plantarum; Listeria monocytogenes; flow cytometry; fluorometry; heat; nisin; temperature; viability
Abstract:
... Lactobacillus plantarum has been exposed to mild heat at temperatures between 48 and 56 degrees C in combination with low concentrations of the lantobiotic nisin in different sequential set-ups. Exposure to heat and nisin caused synergistic reductions of Lact. plantarum viability. Efficient antimicrobial action was dependent on the growth state of the culture as well as on levels and sequences of ...

Abstract:
... D. BRACEY, C D. HOLYOAK AND P J. COOTE. 1998. The effects of sorbic acid and amphotericin B on the growth and intracellular pH (pH₁) of Saccharomyces cerevisiae were studied and compared. Past evidence has suggested that the inhibitory action of sorbic acid on yeast is due to reduction of pH₁ per se. However, using a novel method to measure pH₁ in growing cells, little correlation was found betwee ...

Abstract:
... Aims: The minimum inhibitory concentration (MIC) of oregano essential oil (OEO) and two of its principle components, i.e. thymol and carvacrol, against Pseudomonas aeruginosa and Staphylococcus aureus was assessed by using an innovative technique. The mechanism of action of the above substances was also investigated. Methods and Results: The applied technique uses 100-well microtitre plate and col ...

Abstract:
... In this work, we have used spores of Bacillus subtilis that specifically induce bioluminescence upon initiation of germination as a rapid, real-time monitor of the effects of preservative treatments on germination. Using this tool, we have demonstrated that the combination of mild acidity (pH 5.5 to 5.0), lactic acid (0.5%), and a pasteurization step (90 degrees C for 5 min) results in enhanced in ...
