Research Abstract |
Tellurium(Te) and selenium(Se) oxide ions are lethal toxicants to organisms and cause the serious toxicosia and carcinoma. However, recently, microorganisms capable of reducing Te or Se oxyanions in anaerobic conditions have been found from various environments. Some strains of microorganisms are able to produce intra-and extracellular elemental tellurium nano-particles by the anaerobic respiration. Bioremediation and biominealization due to these microorganisms have currently received increased attention as interesting subjects. In this study, we have achieved the isolation and enrichment of microorganisms capable of producing elemental Te and/or CdTe(or Se and/or CdSe) crystals, and the simultaneous recovery and conversion to useful nano-particles of heavy metals and anionic tellurium(or selenium)-metalloid.
