Research Abstract

The technology for minor-metal removal and recovery from waste and wastewater using minor-metal volatilizations by microbe was developed. Bioreactor using strain NT-I, capable of an efficient volatilization of selenium, successfully removed 66 % of initial selenium in water phase, and recovered it as selenium solution of high purity. Three tellurite-tolerant bacterial strains were isolated, and their capabilities of tellurium volatilization were revealed.
