Morphology and Mn(II) oxidation by strain T-G1: (A) scanning electron micrograph of T-G1 cells, showing abundant extracellular polymeric substances; (B) Mn(II) oxidation by T-G1 as seen by a color change in PYG medium with 10 mM MnSO4 (right) and without Mn (left); and (C) leucoberbelin blue (LBB) spot test on colony of T-G1 showing a blue color change indicative of Mn oxide production.
