Pathways and contributions of sulfate reducing-bacteria to arsenic cycling in landfills
Sulfate reducing-bacteria (SRBs) are generally present in sanitary landfills and have a role in sulfur (S) and metal/metalloid geochemical cycling, but it remains unclear in respond to arsenic (As), which limits our understanding of microbial drivers to control As pollutant in landfills. To address this issue, we investigated the influences of SRBs on As metabolic pathways in the refuse-derived cultures via molybdate (Mo) inhabiting sulfate bio-reduction processes.
