On the 9th day, when exogenous C was depleted again,
C and N were fed simultaneously into the culture again. Algal
cells continued to experience a rapid growth and reached
a maximum cell dry weight of 17.60 g l1 on the 14th day, two
days later than the successive CeN-feeding culture. The
maximum dry biomass concentrations in intermittent and
successive CeN-feeding cultures were similar.
