Abstract

The effect of high nitrate concentration and light intensity on chlorophyll-a synthesis, cell number and nitrate assimilation on P. tJt¿coh,nuutum culture, was determined. Growth and uptake rates were determined as a function of nitrate concentration ranging from 0.40 to 35.40 µg/l. The Ks showed high values, when compared with those obtained with lower nitrate concentration. The percentual variation of Ks was greater than that of Vmax.
