Influences of NH^+_4 as a nitrogen source on pH, dissolved inorganic carbon (DIC) concentrations, dissolved inorganic nitrogen (DIN) concentrations, and recovery of DIC were examined in the culture of Nannochloropsis oculata from the lag phase to the early stationary phase, comparing those chemical parameters of NO_3 as a different nitrogen source. In the treatment with NH^+_4, a rapid decrease of pH was observed when DIC became close to 0 ppm with little or no recovery of DIC. However, no marked changes were observed in DIN concentrations. On the other hand, in the treatment with NO^-_3, higher levels of pH and DIC were maintained. These observations suggest that the differences in the above water quality might be derived from release or absorption of hydrogen ions from or into N. oculata cells.
