Abstract

Minerals that are formed by biolgically induced mineralization processes, generally nucleate and grow extracellulary as a result of metabolic activity and chemical reactions involving metabolic byoproducts. BIM is especially significant for bacteria in anaerobic habitats including deep subsurface sites, or oxic-anoxic interfaces. This s because under anaerobic conditions many bacteria respire involving sulfate and sulfides of various metals, including iron terminal electon acceptors in electron transport. Bacterially-formed minerals may be useful as a biomarcers (indicators of past life) when other remains of the cell or indicators of the presence of the cell are no longer evident.
