biomineralisation


Also found in: Encyclopedia, Wikipedia.

biomineralisation

The process by which microorganisms mediate and catalyse inorganic reactions to form mineralised structures. The goal of biomineralisation as a remediation tool is to control microbial processes and their environment, so as to sequester and immobilise specific heavy metals within exceptionally strong bonds of neo-formed mineral assemblages.
