[Transitional state of Candida utilis chemostat culture after shock caused by a low pH value of the medium during 1 generation].
Transitional states of Candida utilis BKM Y-1668 were found during its growth in conditions of chemostat at D of 0.1 hr(-1) and glycerol limit after a shock caused by an extreme pH value (2.2). The optical density of the cells, the amount of dry biomass and protein, the activity of respiration, the content of ATP, and the activity of ATPase decreased, the character of the decrease being that of damped oscillations. Qualitative changes were detected in the activity of respiration, oxygen uptake was not inhibited by cyanide. More glycerol and phosphorus are utilized in processes of vital activity. Therefore, a sharp change of pH values causes profound changes in the metabolism of the yeast cell.
