Biologically induced mineralization
Biologically induced mineralization occurs when the metabolic activity of microbes (e.g. bacteria) produces chemical conditions favorable for mineral formation. The substrate for mineral growth is the organic matrix, secreted by the microbial community, and affects crystal morphology and composition. See more Biomineralization, also written biomineralisation, is the process by which living organisms produce minerals, often to harden or stiffen existing tissues. Such tissues are called mineralized tissues. It is an extremely … See more Among animals, biominerals composed of calcium carbonate, calcium phosphate, or silica perform a variety of roles such as support, defense, … See more Biomineralization plays significant global roles terraforming the planet, as well as in biogeochemical cycles and as a carbon sink See more Most biominerals can be grouped by chemical composition into one of three distinct mineral classes: silicates, carbonates, or phosphates. Silicates See more The first evidence of biomineralization dates to some 750 million years ago, and sponge-grade organisms may have formed calcite skeletons 630 million years ago. But in most … See more Mineralization can be subdivided into different categories depending on the following: the organisms or processes that create chemical conditions necessary for mineral formation, the origin of the substrate at the site of mineral precipitation, and … See more In nature, there is a wide array of biominerals, ranging from iron oxide to strontium sulfate, with calcareous biominerals being particularly notable.
