Microbially induced carbonate precipitation represents an essential pathway for sequestration of large amounts of carbon in ancient and modern environments (1 – 5) rock records reveal that precambrian stromatolites formed as a consequence of trapping, binding, and precipitation of calcium carbonate by the growth and metabolism of . Limestone is a sedimentary rock composed primarily of calcium carbonate (caco 3) in the form of the mineral calcite it most commonly forms in clear, warm, shallow marine waters it most commonly forms in clear, warm, shallow marine waters. This study reviews different microbial activities related to calcium carbonate precipitation, their occurrence in various geological settings, the application fields of mcp biotechnology, and the challenges for the real applications. Within cave environments, which lack photosynthetic activity and are found predominantly within limestone (caco 3) rock, bacterial species demonstrate a higher incidence of the ability to precipitate calcium carbonate and an overall increase in total caco 3 precipitation levels (cacchio et al 2004 cacchio, p, contento, r, ercole, c, cappuccio .
