Abstract: Current research focused transformation of arsenic, As (III) to As (V) in soil by an efficient bacterial strain (XS9) and successfully transformed 95.4% of As (III) in the soil contaminated with 50 mg/kg and significantly reduced the bioavailable As. After bacterial transformation, we applied two different biochar, produced at 350°C and 650°C at the rate of 2.5, 5 and 10% in the soil, for sorption or stabilization of As (V). We observed that a concentration of 2.5% and 5% biochar efficiently stabilizes the As content as compared to control. Additional, leaching of the treated soil sample was done into the soil column; we found that soil leachate collected at the different time interval (up to 72 h) does not have any soluble/available As. Further, arsenite resistance gene (aioA-gene) was also found in this species (XS9), and strain were identified using 16s rRNA gene sequencing.
