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.}, pages = {21--25}, title = {ナノクロロプシス培地のpHと溶存態無機炭素濃度に及ぼすアンモニウム態窒素の影響}, volume = {50}, year = {} }
