Cultivation of BC cells in an industrial PBR. a BC strain was photoautotrophically grown in batch mode in a 330L-PBR with limited sterility. The numbers on top of each picture indicate the day of growth. b Biomass accumulation curve of BC strain, as measured from the optical density of the cultures at 720 nm. Cultures were inoculated to an initial cell concentration corresponding to OD720 0.037 ± 0.003. Error bars represent standard deviation (n = 4)
