Barium bioaccumulation by bacterial biofilms and implications for Ba cycling and use of Ba proxies

Despite the broad use of barium as a proxy for past ocean export production, the underlying mechanisms of barite precipitation remain unknown. Here, the authors show, under experimental conditions, that barium bioaccumulation on bacterially produced biofilms is the crucial step for barite formation.
