Growth of E. meliloti strains with nitrate. (A) Growth of E. meliloti 1021 (▲) and the napA (■), nirK (), norC (♦) and nosZ (*) mutant strains in MMN under 2% initial O2 conditions. The oxygen consumption by the WT cells is also shown (insert). (B) The extracellular nitrite concentrations of E. meliloti 1021 (▲), napA (■) and nirK () mutant strains. Representative curves of three independent experiments run in triplicate are shown.
