Abstract The rate of incorporation of 14C from CO2 into glycerol, and the amount of glycerol in cells of Dunaliella tertiolecta was determined at constant salinity at two representative concentrations of NaCl. From these data, the rate of synthesis and turnover of the glycerol pool was determined. The half-time for turnover of the glycerol pool was of the order of 1 h in 170 mol m−3 NaCl and almost 6h for 700 mol m−3 NaCl. These results indicate that turnover of the glycerol pool in Dunaliella is relatively slow under steady-state conditions. Synthesis and dissimilation of glycerol do not apparently constitute a metabolic cycle in the conventional sense. Rather, glycerol metabolism resembles that of the storage polysaccharides which arc commonly produced and degraded by different pathways.
