Ranges in which parameters were varied for the Monte-Carlo-sampled simulations for batch TAG production. With I 0: incident light intensity; z: reactor light path; C x, N = 0: biomass concentration at onset of nitrogen (N) starvation, q max, repleteph: maximum photosynthetic rate of nitrogen replete cells, X cho: residual biomass fraction made during N-starvation; N: amount of nitrogen resupplied after each harvest; f: remaining fraction in the reactor after harvest; Δ: cycle duration
