[Effect of elevated temperature on the morphology of a chemostat culture of Candida utilis yeasts and on their content of nucleic acids].

The effect of elevated temperature (40 degrees C) on a chemostat culture of Candida utilis was studied at different rates of dilution, D = 0.1 and 0.3 hr-1. The cells in the fermenter being in the stationary state at the optimum temperature of 30 degrees C were gradually washed-out 5 hours after the action of this temperature, and the population consisted of non-divided cells. In the majority of such "double" cells, the nucleus was contained in both the parent and the daughter parts. The content of RNA decreased by 31%, that of DNA, by 20%, and that of protein, by 13% (per 1 mg of biomass).
