MOESM2 of Microalgal TAG production strategies: why batch beats repeated-batch BenvenutiGiulia LamersPacko BreuerGuido BosmaRouke CerarAna WijffelsRenĂŠ BarbosaMaria 2016 Additional file 2. Nitrogen uptake, biomass and TAG production in repeated-batch cycles. The time at which nitrogen was depleted from the medium, the biomass-specific nitrogen uptake and TAG production rates, as well as the time-averaged biomass and TAG yields on light at the harvest of each cycle are shown for the two repeated-batch cultivations.
