In vitro arsenic transformation assay
In present study B. mycoides NR5 when tested for arsenic ion transformation found that bacterium possess arsenate reduction potential and left yellow precipitate of silver ortho-arsenite (Ag3AsO3) in the medium. Further, to confirm the results obtained from agar plate were repeated through micro plate method and interestingly found the similar results. The quantitative reaction of silver nitrate with arsenic ions resulted in the formation of yellow coloured precipitate that indicates the arsenate reduction potential of NR5.
