NH(4)(+)-Excreting Azospirillum brasilense Mutants Enhance the Nitrogen Supply of a Wheat Host

Spontaneous ethylenediamine-resistant mutants of Azospirillum brasilense were selected on the basis of their excretion of NH(4)(+). Two mutants exhibited no repression of their nitrogenase enzyme systems in the presence of high (20 mM) concentrations of NH(4)(+). The nitrogenase activities of these...
