Biomineralization: Bacteria

This lecture explores two types of biomineralization: microbially-induced, where minerals form as a byproduct of cell metabolic activity, and microbially-controlled, allowing organisms to produce minerals for physiological roles. It delves into the processes of microbial-induced biomineralization, such as oxidation, biosequestration, reduction, bioprecipitation, and biosorption. The lecture also covers the formation of iron minerals, Fe(II) oxidation, and the production of magnetite by certain bacteria. Furthermore, it discusses the role of sulfate-reducing bacteria in biomineralization, the formation of ferromanganese nodules, carbonate precipitation, phosphate biomineralization, and sulfide mineral formation.
