Title

New Isolated Extremophiles Arsenic Oxidizing Bacteria for the Removal of Arsenic from High-and Low-COD Media

Pages

  61-69

Abstract

 There is an urgent need for the removal of Arsenic (As) from groundwater and wastewater as it is a very hazardous heavy metal for human and environmental health. In this research, Asresistant and oxidizing bacteria were isolated from the Maharloo Lake (27 km southeast of Shiraz city) and identified to a great extent. Three isolated bacillus-shaped strains (called F5, F6 and F7) tolerated up to 1 M AsNaO2, grew up to 3. 5 M NaCl and pH 12, and consumed NaSCN and Na2S2O3. The molecular analysis confirmed the originality of the strains to a high extent. The As absorption rate by these bacteria was measured by the atomic absorption method, and their effect was examined on a water sample from the south of Kerman city (Iran) and a synthetic wastewater sample with a chemical oxygen demand (COD) of about 180, 000 kg/m3 that was able to absorb high levels of Arsenic.
