| Research Abstract |
Bacteria, including cyanobacteria, as well as some fungi, are known to deposit calcium carbonate (CaCO3) extracellularly in calcium-containing artificial medium. Despite extensive investigation, the mechanisms involved in extracellular formation of CaCO3by bacteria remain unclear. The ability of synthetic amines to remove carbon dioxide (CO2) from natural gas led us to examine the role of biogenic polyamines in CaCO3deposition by bacteria. Here, we demonstrate that biogenic polyamines do accelerate the formation of CaCO3, suggesting a novel scheme for CO2dissipation that could be a potential tool in reducing atmospheric CO2levels and, therefore, global warming.
