Microbial Mystery: Why Do Some Bacteria Make Environmental Mercury Even More Toxic?

Teaser Title

Why do some bacteria make mercury even more toxic?

Smithsonian Environmental Research Center (SERC) scientists are working to understand why some bacteria convert mercury in the environment to its most toxic form, methylmercury. Humans and animals regularly consume methylmercury because it is concentrated in the tissues of organisms as it moves up the food chain. Understanding more about the bacteria that produce this powerful neurotoxin, through a process known as mercury methylation, may provide clues to mitigating its risks.
