SeptxD-2 cultivation in raceways ponds using phosphite as phosphorus source under non-sterile conditions. a SeptxD-2 transgenic strain was grown in BG-11 media prepared with industrial grade reagents and supplemented 1.8 mM of phosphite (Phi) as P source in 1000-L raceway ponds in non-sterile, outdoor conditions. b Cell number (cells/mL) and c biomass were determined every 2 days during the experiments. Values are the mean of three replicates ± SD (Student’s t test, *P < 0.05, **P < 0.01, ***P < 0.0001). Photographs correspond to experiments carried out during summer, 2019
