(4.13) with transfer and food replenishment being simulated by resetting C
every 2 days. Initial food concentration after transfer was calculated from
the cell density of Chlamydomonas moewusi used by Frank et al. (1957;
9.6 ·10' mrl), assuming the same carbon content as the related C. reinhardi
(0.53 pg C cellO I; Lynch et al. 1986).
