The moving volutin (polyphosphate) granules known as "dancing bodies" can be observed in the vacuoles of the yeast cells. The aim of work was to study the effects of cultivation conditions and influences of physico-chemical factors on the motion of vacuolar volutin granules in Saccharomyces cerevisiae cells. The motion of granules is a non-Markovian process. It does not depend on the cell cycle phase, but depends on the growth stage. The maximal number of cells with "dancing bodies" was observed under cultivation of yeast at 25-28 °C and pH 5.4-5.8. Irradiation by non-ionizing electromagnetic radiation (EMR) of extremely high frequency (61.22 GHz, 100 μW, 30 min) had no effect on granule motion. After irradiation by non-ionizing EMR of very high frequency (40.68 MHz, 30 W, 30 min) the number of cells with "dancing bodies" decreased significantly and in 2 h restored almost to the control value. The possible nature of the moving volutin granules phenomenon due to metabolic processes is discussed.
