All sorted populations are similar to the wildtype (Wt) in the growth phase. The graphs shows the biomass concentration per day (g l−1). The green area (days 0–2) marks the growth phase, hence both populations consumed nitrogen at the same rate. After day 2 all nitrogen was taken up by the cells. From day 2 onwards it should be considered as starvation phase (N−)
