Carbon dioxide and biearbonate in cell division

Carbon dioxide and biearbonate in cell division 203 44 44 3 3 Constantine Sorokin Department of Botany University of Maryland College Park Md. USA Summary The effects of carbon dioxide and of bicarbonate on cell division were studied on synchronized cells of the high-temperature green alga, Chlorella 7-11-05 . After 7 hours of growth in nutrient medium in light, cells were centrifuged and resuspended in distilled water or in bicarbonate and placed in darkness. Atmospheric air, or a mixture of carbon dioxide and air, was bubbled through algal suspensions during the dark period. In distilled water cells readily divided in atmospheric air but not in 1% (2.6·10 -4 M) or in higher concentrations of carbon dioxide. The suspension of cells in bicarbonate counteracted the inhibitory action of carbon dioxide. A minimum molar concentration of bicarbonate necessary to counteract the inhibitory effect of carbon dioxide was found to be equal to the molar concentration of carbon dioxide in the suspending fluid. The highest concentration of carbon dioxide, the adverse effect of which could not be balanced by any concentration of bicarbonate, was found to be in the vicinity of 1.3·10 -2 M (50% CO 2 in air). Possible effects on cell division of the change in Ph and the implicated role of carbon dioxide in normal and neoplastic growth were discussed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Archives of Microbiology Springer Journals

Abstract

203 44 44 3 3 Constantine Sorokin Department of Botany University of Maryland College Park Md. USA Summary The effects of carbon dioxide and of bicarbonate on cell division were studied on synchronized cells of the high-temperature green alga, Chlorella 7-11-05 . After 7 hours of growth in nutrient medium in light, cells were centrifuged and resuspended in distilled water or in bicarbonate and placed in darkness. Atmospheric air, or a mixture of carbon dioxide and air, was bubbled through algal suspensions during the dark period. In distilled water cells readily divided in atmospheric air but not in 1% (2.6·10 -4 M) or in higher concentrations of carbon dioxide. The suspension of cells in bicarbonate counteracted the inhibitory action of carbon dioxide. A minimum molar concentration of bicarbonate necessary to counteract the inhibitory effect of carbon dioxide was found to be equal to the molar concentration of carbon dioxide in the suspending fluid. The highest concentration of carbon dioxide, the adverse effect of which could not be balanced by any concentration of bicarbonate, was found to be in the vicinity of 1.3·10 -2 M (50% CO 2 in air). Possible effects on cell division of the change in Ph and the implicated role of carbon dioxide in normal and neoplastic growth were discussed.
