A silver-white metallic compound made from the mineral barite.

(Barium sulfate, NCI Dictionary)

Barite, a mineral compound of barium, is now a direct and accurate proxy for marine productivity, marine climate, and marine life evolution in general.

Now, a study carried out by researchers from the University of Granada (UGR) and the Spanish National Research Council (CSIC) has proven that bacteria may play a crucial role in barite precipitation.

At the initial stages of barium bioaccumulation this element binds to phosphate groups present in EPS, thus forming an amorphous precursor which later evolves to barium sulfate (barite crystals) after replacing phosphate groups with sulfate groups.

Experiments carried out with diverse marine bacteria shed light on the processes by which barite precipitates in bacterial biofilms from the bioaccumulation of barium in bacterial cells and extracellular polymeric substances (EPS), Francisca Martínez Ruiz and María Teresa González Muñoz, researcher from the Andalusian Earth Sciences Institute (IACT) and professor emeritus of the Department of Microbiology at the UGR, respectively, explain.
