Aim and Background: Selenium had a complete bicycle and in slight density nanogram can affect the life of any animate beings. Almost of animate and living beings especially microorganisms are involved in to the biogeochemical transformation of this element. The aim of this study was to isolation of strains of bacteria with ability of biodegradation and selenite reduction from activated sludge and glass manufacture.
Material and Methods: After evaluation of measure of resistance to sodium selenite by determination MIC, its reduction was charectrized by the colorimetric and atomic absorption spectrometry techniques. Identification of isolated strains was applied by 16SrRNA sequencing.
Results: The obtained results showed that strains of Bacillus licheniformis isolated from glass manufacture were more resistant than Pesudomonas aeruginosa isolated from Ghetarie of wastewater and have been the ability of complete reduction of selenite to elemental selenium.
Conclusion:The main characteristic of these resistance bacteria in bioremediation of selenite can help to cleaning of environmental pollutants from these oxoanions.
