Description
To understand the influence of bacterial metabolic activity at calcite crystallization, we synthesized hydrogel-calcite composite aggregates with B. subtilis. Our results show that living microorganisms strongly influence the mineral microstructure and texture. This characteristic indicates that bacterial EPS can be developed as a further tool (a biomarker) for the recognition and identification of bacterially mediated calcification in present environments as well as in the geological record.
