cultures performed at different carbon dioxide feeding rates (F= 0.44–1.03 gL− 1d− 1) and
photosynthetic photon flux density (PPFD= 80–250μmol photons m− 2s− 1) in a bench-scale
helical photobioreactor. To achieve this purpose, an inorganic medium lacking the carbon
source was enriched by gaseous carbon dioxide from a cylinder. The maximum cell
concentration achieved was 12.8 gL− 1 at PPFD= 166μmol photons m− 2s− 1 and F= 0.44 …
