(Intro about biosequestration)
Surveying evolved strategies for arsenic detoxification in bacteria shows that the most common mechanisms involve the efflux of arsenic ions. If we're trying to biosequester arsenic then efflux mechanisms will work counter to our goal. However, storage of free arsenic ions in a cell will be toxic. Therefore a successful arsenic sponge needs to incorporate both a mechanism to prevent efflux as well as binding arsenic in a non-toxic form.
