Abstract:Arsenate reduction is a major cause of As release from soils which threatens more than 200 million people worldwide. While heterotrophic As(V) reduction has been investigated extensively, the mechanism of chemolithotrophic As(V) reduction is less studied. Since As is frequently found as sulfidic minerals in the environment, microbial mediated sulfur oxidation coupled to As(V) reduction (SOAsR), a chemolithotrophic process, may be more favorable in oligotrophic mining-impacted sites (e.g., As-contaminated mine … Show more
