Arsenate-Tolerant Bacteria from Mono Lake. Part 1: Another Perspective

Figure 1: Metabolism of arsenic compounds in bacteria Arsenic (As) is widely distributed in the lithosphere, hydrosphere and biosphere. Discovered in 1250 by Albertus Magnus, it has since become synonymous with poison. As, the 33 element on the periodic table, falls just below phosphorus (P), meaning that As shares physicochemical properties with that of P, […]
