Abstract

Disorientation of daughter colonies of Pediastrum was induced by reduction of the bicarbonate ion concentration in the culture medium. Threshold values were established for disorientation by the use of two sources of bicarbonate ions. Below these threshold values daughter colonies were disoriented; above them, oriented. When placed in new solutions having bicarbonate ion concentrations above the threshold values, colonies which were disoriented by bicarbonate ion deficiency produced oriented daughter colonies. When placed into new solutions having higher bicarbonate ion concentrations, colonies cultured in solutions with bicarbonate ion concentrations above threshold values increased cell divisions in the mother cells and hence produced more cells in daughter colonies.
