Influence of inoculum nitrate concentration and nitrogen feeding factor \(N_D\) on biomass (top), \(\upbeta\)-carotene fraction (middle) and total \(\upbeta\)-carotene amount (bottom). For the experiment, inoculum nitrate concentration was at \(0.08\,{\rm g}/{\rm L}\). We thus chose \(N_D=0.02\,{\rm g}_{\mathrm {N}}{\rm L}^{-1}{\rm h}^{-1}\)
