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.
