Batch nitrogen run-out cultivations. Time-evolution of a biomass (C x) and N–NO3 (CN–NO3 ) concentrations, b volumetric (a x, vol) and biomass-specific (a x,) absorption cross section, c TAG concentration (CTAG) and content (f TAG), d polar lipid concentration (C PL) and content (f PL), e carbohydrate concentration (C carbs) and content (f carbs), f estimated protein concentration (C prot) and content (f prot). The dotted line indicates the time point at which extracellular N-NO3 concentration was zero. Data points for each of the duplicate cultivations are reported, indicating a very high degree of reproducibility
