S. vacuolatus ACUF_053 a nitrogen (NO3-N) and phosphorus (PO43−-P) removal kinetics in the PBR under semi-batch conditions; b pH changes in the medium of the biofilm photobioreactor and, c microalgal biomass growth in the medium of the biofilm PBR. The numbers define the development phases: (1) attachment, (2) biofilm formation, (3) maturation I, (4) adaptation and (5) maturation II
