  "abstract": "Manganese contamination in soil poses risks to plant growth and human health. In this study, we isolated the manganese-oxidising bacterium Bacillus wiedmannii DX3 from electrolytic manganese residue and investigated its Mn(II) oxidation characteristics. The strain exhibited efficient Mn(II) oxidation at different initial Mn(II) concentrations, with a maximum biogenic manganese oxide (BMO) production of 166.89 μM achieved at 5.0 mM Mn(II). Spectroscopic analysis revealed that Mn(III) serves as a key intermediate during microbial Mn(II) oxidation. The biogenic manganese oxides were further characterised using transmission electron microscopy (TEM), X-ray diffractometry (XRD), and X-ray photoelectron spectroscopy (XPS), providing insights into their structural and functional properties. Overall, this study expands our understanding of manganese-oxidising bacteria and provides a mechanistic basis for the potential application of strain DX3 in the bioremediation of manganese-contaminated environments. The biogenic manganese oxides produced through the Mn(II) → Mn(III) → Mn(IV) pathway act as adsorbents for toxic metals and as oxidants for redox-sensitive contaminants. However, their efficacy in real soil and water matrices, as well as the biosafety of this B. wiedmannii strain, requires further evaluation.",
