Cell suspensions maintained in the presence of
light entered the exponential phase after three days of culture.
This pattern was maintained until the 10th day, when cultures
reached 3-fold increase on biomass accumulation (Fig. 3a). On the
other hand, cultures maintained in darkness displayed the exponential
phase between days 15 and 20, also with 3-fold increase
on biomass accumulation (Fig. 3b). Following the stationary phase,
cultures showed a decrease in cell density, recorded by both fresh
and dry weights (Fig. 3a and b)
