Prochlorococcus MED4 was acclimated to low (150 ppm) or high (1000 ppm) CO2. The cultures were then concentrated and placed in the chamber of a membrane inlet mass spectrometer (MIMS; Pfieffer QMS220). Dissolved inorganic carbon (DIC) was gradually added to the culture and inorganic carbon fluxes were measured using MIMS as described in Hopkinson et al. 2014.
