Definition

Bioprecipitation refers to the process of formation of mineral phases (bioprecipitates or biominerals) by organisms. Cells or associated extracellular polymers can serve as nucleation surfaces and/or alter the chemical composition of fluids and raise the supersaturation of the solution with a mineral phase. Alternatively, bioprecipitation has been used in meteorology to refer to the nucleation of ice by bacteria in clouds resulting in snow or rainfall.
