Inorganic polyphosphate is involved in metal homeostasis in microorganisms. The aim of the study was to reveal differences in polyphosphate metabolism of Rhodospirillum rubrum under autotrophic and heterotrophic cultivation in the presence of Fe (2.3 mg Fe³⁺ L⁻¹) and without Fe (traces). Heterotrophic conditions without Fe resulted in cell lysis an...
Bacteria are the simplest model of living organisms and thus are a convenient object for magnetobiological research. This paper describes some effects of combined magnetic fields (CMFs) on the bacterium Rhodospirillum rubrum strain VKM B‐1621, which is not a pathogen but was selected due to its wide spectrum of growth abilities. The authors chose m...
Yeasts Cryptococcus humicola accumulated cadmium, cobalt, and iron (~ 50, 17, and 4% of the content in the medium, respectively) from the medium containing glucose, phosphate, and 2 mmol/L of metal salts. The effects of metal absorption on the levels of orthophosphate (Pi) and inorganic polyphosphate (polyP) varied for the metals under study. The l...
The paper presents effects of different magnetic fields (MFs) (static—SMF and impulse—IMF) on bacteria Rhodospirillum rubrum VKM B-1621. The MFs had different magnetic strength: SMF—up to 173 mT; IMF—25 mT. The studied object was amylase activity which was measured by decrease in the starch concentration during incubation in the MFs. The term of in...
