Molybdate Reduction to Molybdenum Blue by an Antarctic Bacterium

Figure 7

The effects of phosphate concentrations on molybdate reduction by isolate DRY1. Isolate DRY1 was grown statically at 20°C for 72 hours in 50 mL liquid medium (pH 7.0) containing (w/v) glucose (1%), MgSO₄⋅7H₂O (0.05%), NaCl (0.5%), yeast extract (0.05%), ammonium sulphate (0.2%), Na₂MoO₄⋅2H₂O (1.21%), and various phosphate (Na₂HPO₄⋅2H₂O) concentrations. Error bars represent mean ± standard error (𝑛=3).
