Looking for the mechanism of arsenate respiration of sp. strain 3D3, independent of ArrAB.

The literature has reported the isolation of arsenate-dependent growing microorganisms which lack a canonical homolog for respiratory arsenate reductase, ArrAB. We recently isolated an arsenate-dependent growing bacterium from volcanic arsenic-bearing environments in Northern Chile, sp. strain 3D3 () and studied the arsenic metabolism in this Gram-positive isolate.
