[Simultaneous action of environmental factors on Candida utilis growth in a chemostat culture]

The effect of carbon dioxide and carbon-containing metabolites on the growth of Candida utilis was studied under the conditions of phosphate limitation. The limiting factor and the hydrocarbonate form of CO2 were shown to act simultaneously on the yeast growth, decreasing its rate. The threshold concentration of the limiting factor remained unchanged. Carbon-containing metabolites produced a similar action on the chemostat yeast culture. The factors limiting the rate of the yeast growth did not switch over.
