The first report dealing with the effect of temperature on the nutritional requirements of microorgsms seems to be that of Mitchell and Houlahan (1946a). In the course of their genetic studies on Neurospora a mutant strain was isolated which required riboflavin for growth. They noted that this requirement was a function of the incubation temperature. When the mutant was grown at temperatures be...

MarA activates two membrane dependent mechanisms of resistance to different antibiotics, such as ciprofloxacin and tetracycline, including promotion of outflux and inhibition of influx of antibiotics. Thus, MarA causes multiple antibiotic resistance phenotype. The activation of these mechanisms needs overexpression of marA. This could happen through mutation in marR. Thus, the aim of this study...

We report here the use of immunomagnetic (IM) electrochemiluminescence (ECL) for quantitative detection of Esherichia coli O157:H7 in water samples following enrichment in minimal lactose broth (MLB). IM beads prepared in-house with four commercial anti-O157 monoclonal antibodies were compared for efficiency of cell capture. IM-ECL responses for E. coli O157:H7 (strain SEA13B88) were similar fo...

The aim of the work was to study biological activity modifiers and carbon sorbent samples modified by them in relation some types microorganisms. Material methods . under were obtained at Center New Chemical Technologies BIC. Glycolic acid, lactic glycine, glutamic acid used as modifiers. Strains Staphylococcus aureus ATCC 25923, Pseudomonas aeruginosa 27853, Klebsiella pneumoniae 418, Esherichia ...
