Outline of Final Research Achievements

For developing a biological treatment process for removing antimony from water, antimony-reducing bacteria were enriched and characterized. Various microbial samples collected from water of Yodo River, Lake Biwa, Aso Sea, Wakasa Bay, and soil of forests in Hyogo, and sewage treatment sludge showed orange precipitates of antimony sulfide (Sb2S3) under anaerobic conditions. Some samples showed white precipitates of antimony oxide (Sb2O3), resulting in removal of antimony from the water phase. Bacterial colonies with antimony reducing ability were formed on the solid media. In conclusion, promising results were obtained for developing antimony removal technology.
