The simultaneous production of carbonic anhydrase and the phycobiliproteins, C‐phycocyanin and allophycocyanin, was evaluated during the cultivation of Spirulina platensis using Zarrouk's medium in its non‐diluted (100 % ZM) and diluted to 20 % (v/v) (20 % ZM) forms. In both media, Spirulina simultaneously produced carbonic anhydrase and phycobiliproteins. For the phycobiliproteins’ production, higher concentrations (mg/g) of C‐phycocyanin and allophycocyanin were obtained when 100 % ZM was used. For carbonic anhydrase production, higher concentrations (U/g) were obtained on the 6 th day of cultivation in both culture media. 100 % ZM promoted greater productions of these bioproducts, and, for simultaneous obtainment, the cells should be harvested after 21 days, obtaining concentrations of 137.4 mg/g C‐phycocyanin, 104.4 mg/g allophycocyanin, and 26.6 U/g carbonic anhydrase.
