Abstract
The mode of increase in cell wall polysaccharides of yeast (glucan and mannan) during cell cycle was analyzed using cell wall samples obtained from a synchronous culture. The increase in mannan and total glucan proceeded almost linearly throughout the cell cycle except for a short period of their leveling off at the time of cell division. However, the constituents of glucan behaved characteristically: Alkalisoluble glucan and insoluble glucan increased mainly in the former and the latter half of the cell cycle, respectively.
