Cultivation of Synechococcus with different nitrate concentrations. (A) Initial NaNO3 concentration of 1 g L-1. (B) Initial NaNO3 concentration of 0.24 g L-1. Solid circles: OD730 (optical density at 730 nm); solid squares: total carbohydrates per cell dry weight (% weight per weight); open squares: NaNO3 concentration (g L-1); open circles: relative phycobilisome content per cell. h, hours.
