An Mn-oxidizing fungus was isolated from a constructed wetland of Hokkaido (Japan), which is receiving Mn-impacted drainage, and genetically and morphologically identified as a Paraconiothyrium sp.-like strain. The optimal pH range for Mn oxidation was found to be between 6.45 and 6.64, which is more acidic compared to previously reported Mn-oxidizing fungi. Excess and deficiency of nutrients inhibited Mn oxidation at optimal pH. To effectively oxidize high concentrations of Mn, such as those in mine drainage, it is critical to determine the ideal mix of initial Mn concentrations, inoculum size, and nutrient concentrations. The strain displayed tolerance to Mn concentrations exceeding 30 g m⁻³, though the oxidation of high Mn(II) levels was restricted by pH control and nutrient supply. The fungal deposit was identified as poorly crystallized birnessite. This unique strain, characterized by high tolerance to Mn and weakly acidic conditions, has no prior records of such properties, indicating potential applications in environmental bioremediation.
