Mechanisms of biomineralization
Summary[edit]
| Description |
English: Schematic illustration of biomineralization mechanisms. Microorganisms can cause a mineral to form by changing the chemistry of a solution such that the mineral become supersaturated and by forming biomass that provides nucleation surfaces. As an example, microorganisms can promote carbonate precipitation by producing bicarbonate and consuming hydrogen ions, which would help drive the minerals to supersaturation, and by producing biomass that complexes metals such as calcium and magnesium, which then serve as nucleation sites. That biomass can include extracellular polymeric substances (EPS), as depicted, as well as the cells themselves. Note that the figure is not to scale and that the relative size of ions is greatly exaggerated. |
