Mn(II), Mn(III)-citrate, and Mn(III)-DFOB oxidation over time by (A) P. hunanensis GSL-007, (B) Pseudomonas sp. GSL-010, (C) P. putida GB-1 alongside associated mutants—(D) P. putida KG_mnxG (producing only MnxG), (E) P. putida KG_mcoA (producing only McoA) and (F) P. putida KG_mopA (producing only MopA)—as measured by Mn(III,IV) oxide formation. Mn(II) was used as a positive control with (G) sterile medium and (H) P. putida TKO (devoid of any Mn oxidase genes) serving as negative controls. Grown in minimal media at 30°C containing 100 μM of relevant Mn compound. Relative growth between bacterial isolates was normalized by OD600 (results not shown).
