title: Control of the cell cycle of Candida utilis by external conditions.
abstract: A mathematical model of the cell cycle of Candida utilis in a continuous culture was formulated with respect to dilution rate. It makes it possible to express the duration of morphological stages in minutes, separately for mother cells and daughter cells. These values were compared with equivalent parameters in batch cultures. Duration of the morphological stage with buds was much longer in batch cultures as compared with the same value determined for a continuous culture according to the mathematical model. When using cultivation apparatus with a higher aeration capacity the (S + G2) phase, i.e. the stage bearing the bud, was reduced also in the batch cultures and approached the values determined for the continuous culture by means of the mathematical model.
