Abstract
Uptake rates for dissolved nitrogen (DN) by a marine alga (Oocystis borgei) were examined in a 15N tracer experiment. Maximal uptake rates for all forms of DN were observed at temperatures between 25 and 30°C and at algal concentrations between 3.22 × 108 and 4.78 × 108 cell L−1. Light intensity required to achieve the maximal uptake rate was 45 μmol m−2 s−1 for dissolved inorganic nitrogen (DIN = NO3 −, NO2 −, NH4 +) and methionine, and 126 μmol m−2 s−1 for urea. Salinity required to achieve the maximal uptake rate was 12.85 ppt for DIN, 19.89 ppt for urea and 26.2 ppt for methionine.
