Organosulfur compounds found in industries like pulp and paper, biogas, and natural gas can harm health and the environment. Scientists showed that these compounds can be broken down into sulfide using bioelectrochemical systems. By supplying different organosulfur compounds to the systems, they found that 64% of sulfur was recovered from methanethiol in 5 days. Over 22 days, 18-22% of sulfur was recovered from other compounds. No sulfur was produced without both electricity and microorganisms. This new method could help reduce harmful organosulfur emissions.
