 note = {The growth of Chlorella cells cultured in synchronization system was studied in order to maintain the strain with a stable life cycle for practical use as food of marine rotifer. Two experiments, Exp. I and Exp. II , were carried out using a marine type of Chlorella sp. acclimated to 16L-8D photoperiod for 15- and 180-days, respectively. Water temperature was controlled constantly at 23.0°C. A Coulter Counter with a 30μ aperture tube and a size distribution analyzer was used for the measurements of the cell number and diameter. Increase in cell number is indeed diurnally periodic, with a doubling of number occurring between 11 p.m. and 2 a.m. in Exp. I, and between 2 a.m. and 4 a.m. in Exp. II. Cell divisions were found mainly at midnight in Exp. I and at 3 a.m. in Exp. II. It was considered that the cells in Exp. I were still persisted the solar photoperiod. Consequently, to maintain the strain with a stable life cycle, more than 15 days are necessary to acclimate to a new photoperiod.},
