Effect of pH, temperature, and potassium sorbate on amino acid uptake in Salmonella typhimurium 7136.
The effect of sorbate on L-serine and L-histidine uptake in Salmonella typhimurium was studied at various pH levels, temperatures, and amino acid and sorbate concentrations. Low pH had an apparent synergistic effect on amino acid uptake inhibition caused by sorbate. The relationship between sorbate concentration and the amount of amino acid uptake inhibition was not linear. Compared with L-hist...
متن کاملMembrane lipid alterations and thermal stress in Salmonella typhimurium 7136.
Salmonella typhimurium ATCC 7136 exhibited major changes in lipid composition when grown in the presence of either 0.15% sodium deoxycholate or 0.15% sodium benzoate. These lipophilic compounds had directly opposing effects on the lipid profile of the organism. The saturated/unsaturated ratio was markedly elevated in benzoate-grown cells. On the other hand, it was depressed by an even greater m...

15 صفحه اولModeling of Salmonella typhimurium growth under the effects of Carum copticum essential oil, temperature, pH and inoculum size
The purpose of this study was to elucidate some factors affecting the growth of Salmonella typhimurium. These factors included Carum copticum essential oil (0%, 0.015%, 0.03% and 0.06%), temperature (25 ˚C and 35 ˚C), pH (5, 6 and 7) and inoculum size (103 and 105 CFU mL-1). Brain heart infusion broth was used as the growth medium. There...
