Однако внесение дополнительного количества фосфора в агаризованную среду YEPD улучшало визуализацию реакции метахромазии. Исследование клеток на разных стадиях развития показало, что возраст культуры не влияет на метахроматическое окрашивание. Штамм S. cer evisiae УКМ Y-517 рекомендуется для проведения мониторинговых исследований в проекте «Гелиомед» как высокочувствительный штамм для исследований влияния космической погоды на микроорганизмы. Данная работа является продолжением исследования био-астрономического эффекта Чижевского-Вельховера. К л ю ч е в ы е с л о в а: дрожжи, метахромазия, волютиновые гранулы, космическая погода.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
