Abstract. Scanning electron microscopy and X-ray dispersive energy microanalysis were used to investigate the formation of carbonate crystals by Deleya halophila. The formation of calcium carbonate crystals (polymorphous aragonite) by D. halophila is a sequential process that commences with a nucleus formed by the aggregation of a few calcified bacterial cells and the subsequent accumulation of more calcified cells and carbonate, which acts to weld the bacteria together. The process leads to… 
Amorphous Ca-phosphate precursors for Ca-carbonate biominerals mediated by Chromohalobacter marismortui
TLDR
The study of aragonite precipitation by Chromohalobacter marismortui during the early stages of culture experiments, and its relation to bacterial metabolic pathways, shows that carbonate nucleation occurs after precipitation of an amorphous Ca phosphate precursor phase on bacterial cell surfaces and/or embedded in bacterial films.
Biomineralization processes of calcite induced by bacteria isolated from marine sediments
TLDR
Evidence is provided that a variety of marine bacteria can induce calcium carbonate precipitation, and may influence the marine carbonate cycle in natural environments.

TLDR
Preliminary examination, isolation and partial sequencing of 16S rRNA gene showed that the major microbial population participating in calcite precipitation is heterotrophic and includes mainly Bacillus sp.
Calcium Carbonate Crystals Formation by Ureolytic Bacteria Isolated from Australian Soil and Sludge
Ureolytic bacteria were isolated selectively from sludge and soil samples (Perth, Western Australia). Three isolates were genetically examined by 16S rRNA. They were mostly closely related to

The mechanism of calcium and magnesium uptake from sea water by a marine bacterium.
TLDR
The mechanism of the process of calcium-binding by cells is the subject of this study, and the complex formation by ammonia and Ca, coupled with the increase in pH, favors binding of calcium over that of magnesium by the cells.

Numerical Taxonomy of Moderately Halophilic Gram-negative Bacteria from Hypersaline Soils
TLDR
The bacteria found in these environments are not related to those from hypersaline waters or normal soils, and the high G + C composition of a representative strain of this phenon suggests that it may represent a new taxon.
