Abstract(s) :

(Anglais) The ability of autotrophic cyanobacteria Arthrospira sp. PCC 8005, to thrive and grow using waste nitrogen (both organic and inorganic) and release oxygen has made it a potential candidate for the production of oxygen for astronauts in the MELISA loop. The present case study evaluated the growth profile, biomass productivity and oxygen productivity of Arthrospira sp. PCC 8005 in a photobioreactor (PBR) operated under turbiostat conditions. Four transitions between nitrate (NO3-) and Ammonium (NH4+) as the nitrogen (N); were made over a period of 100 days.
