[Effect of cultivation conditions on the age structure of a yeast population].
The work was aimed at studying the effect exerted by mineral components of the medium and a carbon source limiting the growth of Candida boidinii and Saccharomyces cerevisiae as well as by the dilution rate in the course of chemostat cultivation and by the temperature of growth on the age structure of a population, i.e. on the proportion of cells at different phases of the cell cycle. Nitrogen, phosphorus and magnesium deficiency delayed the growth of cells in the G1 phase and, if the growth rate was low, at the end of budding. The rise of the growth rate increased the proportion of budding cells. A temperature drop below 23 degrees C delayed the separation of the daughter and mother cells.
