Survival of adhering staphylococci during exposure to a quaternary ammonium compound evaluated by using atomic force microscopy imaging.
Effects of a quaternary ammonium compound (QAC) on the survival of adhering staphylococci on a surface were investigated using atomic force microscopy (AFM). Four strains with different minimal inhibitory concentrations (MIC) and minimal bactericidal concentrations (MBC) for the QAC were exposed to three different concentrations of the QAC in potassium phosphate buffer (0.5×, 1×, and 2× MBC) wh...
متن کاملThe Listeria monocytogenes transposon Tn6188 provides increased tolerance to various quaternary ammonium compounds and ethidium bromide.
Tolerance of the foodborne pathogen Listeria monocytogenes to sublethal concentrations of disinfectants has been frequently reported. Particularly, quaternary ammonium compounds (QACs) such as benzalkonium chloride (BC) are often used in disinfectants and also as antiseptics in food industry and hospitals. Recently, we described Tn6188, a novel transposon in L. monocytogenes harbouring the tran...
متن کاملPhotodynamic Inactivation of Food Pathogen Listeria monocytogenes
The aim of this study is to examine the possibility to inactivate food pathogen Listeria monocytogenes by nonthermal antimicrobial treatment – photosensitization. L. monocytogenes was incubated with 5-aminolevulinic acid (ALA) (7.5 mM) for 0–2 h to produce endogenous photosensitizers and then illuminated with visible light. The LED-based light source used for the illumination of L. monocytogene...

متن کاملStudies on UV-Visible, Fluorescent Spectral Properties and Solvatochromic behavior of Naphthalimide Compound Containing Quaternary Ammonium
This paper presents the results of absorption spectra, fluorescence properties and the effect of solvents on UV-Vis spectra of dye quaternized 4-acetylamino-N-2-aminomethylpyridine-1,8-naphthalimide. The fluorescency of the dye was evaluated and its Stokes shift value was 6140 cm-1 in DMF. The solvatochromism behavior of the novel compound is investigated by studying its spectra in pure organic...
