Table 2 Comparison of our best case with a similar nitrogen-starvation study reported in literature

From: Microalgal triacylglycerides production in outdoor batch-operated tubular PBRs

  1. Microalga used, initial biomass concentration (C x (0)), duration of the cultivation, reactor type, volume-to-ground area ratio (V/A ground ), TAG productivity (P TAG, batch ), TAG content (f TAG, batch ) and initial-biomass-specific TAG production rate (r TAG, IBS, batch ) at the end of the batch are shown for each study. The TAG productivity reported by [14] was re-calculated using the duration of the actual batch cultivation under N-starvation (i.e. 12 days), neglecting the time necessary to produce inoculum in chemostat-mode.
