Nutrient consumption during growth of NsbHLH2 transformants. a Nutrient uptake was estimated by measuring concentrations of nitrate (a, c, e) and phosphate (b, d, f) in the culture media under normal (a, b), N limitation (c, d), and osmotic stress conditions (e, f). Cells were cultivated at 25 °C, 120 rpm, 120 µmol photons/m2/s of fluorescent light, and 0.5 vvm of 2 % CO2. Data points represent means and standard errors (n = 4)
