Molybdate Reduction to Molybdenum Blue by an Antarctic Bacterium

Figure 5

The effect of initial pH on molybdate reduction by isolate DRY1. Isolate DRY1 was grown statically at 20°C for 72 hours in 50 mL low phosphate liquid medium at various pHs containing (w/v) glucose (1%), MgSO₄⋅7H₂O (0.05%), NaCl (0.5%), Na₂MoO₄⋅2H₂O (0.242%), yeast extract (0.05%), Na₂HPO₄⋅2H₂O (0.05%), and ammonium sulphate (0.2%). Error bars represent mean ± standard error (𝑛=3).
