[Title of award-winning research]
?Effect of iron-oxidizing bacteria in acid mine drainage water from Date Mine on wastewater treatment

[Details of award-winning research]?
　More than 70 abandoned mines across Japan still produce mine wastewater containing high concentrations of heavy metals, and treating it requires significant costs. Therefore, the use of iron-oxidizing bacteria (IBRs) is being considered as a low-cost alternative to the currently mainstream chemical treatment. IBRs are believed to be able to oxidize iron up to 10 times faster than inorganic oxidation in acidic environments, and this ability is being utilized in wastewater treatment. In this study, we investigated how seasonal changes in mine wastewater quality relate to the activity of IBRs. We conducted various on-site environmental measurements, chemical analysis of wastewater, and microbiological analysis in the laboratory to clarify the relationship between water quality and IBRs.
