As(V)/sulfate/Fe(III)-reducing bacterial enrichment recuperated from arsenic contaminated sediments

A bacterial enrichment recovered from arsenic-contaminated sediments, was used as inoculum in batch experiments to investigated the role of the microbial reduction of As(V), sulfate, and Fe(III) in arsenic solubilization from calcite, gypsum and ferrihydrite, was also assessed the arsenic remineralization as consequence of the new formed mineral phases. At the end of the experiments, was determined the composition of the microbial community to contrasting between the different treatments.
