Abstract

Summary: A description is given of the vegetative growth of in liquid cultures. When a circadian light/dark regime is applied, cell division takes place during the dark periods and the release of the daughter cells is phased round the dark/light transitions. However, as long as the cultures are agitated, only a fraction of the cells divides during any dark period. The mother cells stick firmly to the surface of the culture vessels, making it possible to separate them from the non-dividing cells. They release daughter cells that show cell cycles of 1 x 24 h, 2 x 24 h and longer. Only in static cultures do all cells divide synchronously every 24 h. To explain these results, a correlation is postulated between the chance of settling and the length of the division cycle.
