abstract = {Although diverse microbial metabolisms are known to induce the precipitation of carbonate
minerals, the mechanisms involved in the bacterial mediation, in particular nucleation, are still
debated. The study of aragonite precipitation by Chromohalobacter marismortui during the early
stages (3–7 days) of culture experiments, and its relation to bacterial metabolic pathways, shows
that: (1) carbonate nucleation occurs after precipitation of an amorphous Ca phosphate precursor
phase on bacterial cell surfaces and/or embedded in bacterial films; (2) precipitation of this
precursor phase results from local high concentrations of PO4
3 and Ca2 þ binding around bacterial
cell envelopes; and (3) crystalline nanoparticles, a few hundred nanometres in diametre, form after
dissolution of precursor phosphate globules, and later aggregate, allowing the accretion of
aragonite bioliths},
