In this study, denitrification linked to the oxidation of arsenite (As(III)) to arsenate (As(V)) was shown to be a widespread microbial activity in anaerobic sludge and sediment samples that were not previously exposed to arsenic contamination. When incubated with 0.5mM As(III) and 10mM NO(3)(-), the anoxic oxidation of As(III) commenced within a few days, achieving specific activities of up to 1.24mmol As(V) formed g(-1) volatile suspended solids d(-1) due to growth (doubling times of 0.74-1… CONTINUE READING
