Nitrogen-limited continuous cultures of Cyanidium caldarium contained induced levels of glutamine synthetase and nitrate reductase when either nitrate or ammonia was the sole nitrogen source. Nitrate reductase occurred in a catalytically active form. In the presence of excess ammonia, glutamine synt
