RESUMO

Nitrate assimilation is the principal route for plants and algae to acquire inorganic nitrogen. Nitrate reductase is a multi-enzyme complex bound in the cell membrane in both active and inactive forms. Nitrate reductase is the limiting factor when considering the growth and protein production of algae. Heavy metals interacted negatively with the nitrate reductase (NR) enzyme activity of Chlorella vulgaris Beijer. Nickel was found to be more toxic compared to zinc and cadmium. A highly significant increase in NR activity was observed in the immobilized cells over free cells when supplemented with Ni.
