Effect of Molybdenum Starvation and Tungsten on the Synthesis of Nitrogenase Components in Klebsiella pneumoniae

RESUMO
Klebsiella pneumoniae M5a1 grows well in the presence or absence of molybdenum in media containing excess NH4+. However, growth on N2 is completely dependent on the presence of molybdenum in the medium. Tungstate competes with the molybdate requirement during growth on N2. In molybdenum-depleted medium, neither protein component of nitrogenase is active and neither component can be detected antigenically. These data provide evidence that molybdenum is an inducer of nitrogenase synthesis.
