The threat of arsenic (As) pollution being severe warrants opting for low cost microbial remediation strategies. Our present study of identifying suitable bacterial strain led to isolation of As-tolerant strain from the As contaminated soil of West Bengal, India. The isolated bacterial strain LAR-2 had a high MIC (minimum inhibitory concentration) towards As(V) (300.67 mM) and As(III) (31.3 mM) and transformed 78.4% of arsenite to arsenate under laboratory condition. Based on 16S rRNA homology the LAR-2 was identified as Burkholderia sp (MK634685) and emerged as the most potent strain for As decontamination.
