Abstract
Continuous culture studies have been carried out on a strain of A, bra silense to study ammonia excretion, dinitrogen fixation and ammonia as similatory enzymes (glutamate-ammonia ligase and glutamate synthase (N ADPH)) in encysted conditions. High glutamate synthase (NADPW) and low ammonia excretion was observed at the time of induction of cyst forma tion. Low and oscillating nitrogenase activity was observed throughout the experiment.
