Photosynthetic carbon assimilation is commonly invoked as the cause of calcium carbonate precipitation in cyanobacterial biofilms that results in the formation of calcareous stromatolites. However, biofilm calcification patterns in recent lakes and simulation of photosynthetically induced rise in calcium carbonate supersaturation demonstrate that this mechanism applies only in settings low in dissolved inorganic carbon and high in calcium. Taking into account paleo–partial pressure curves for… 

Microbial metabolisms and calcification in freshwater biofilms

In this study, biofilms of two CO2-degassing karst-water creeks in Germany, which attain high calcite supersaturation during their course downstream, were investigated with regard to the effects of

Intracellular Ca-carbonate biomineralization is widespread in cyanobacteria

It is discovered that diverse unicellular cyanobacterial taxa form intracellular amorphous Ca-carbonates with at least two different distribution patterns, suggesting the existence of at leastTwo distinct mechanisms of biomineralization.

Photosynthetic uptake of inorganic carbon can raise the pH adjacent to cyanobacterial cells, promoting CaCO3 precipitation. This effect is enhanced by CO2 concentrating mechanisms that actively

Insight into calcification of Synechocystis sp. enhanced by extracellular carbonic anhydrase

It is suggested that extracellular carbonic anhydrase of cyanobacteria enhanced CaCO3 precipitation from calcium and bicarbonate through facilitating the proton consumption during transformation of bICarbonate to carbon dioxide.

Mesoproterozoic carbon dioxide levels inferred from calcified cyanobacteria

Filamentous and shrub-like carbonate fabrics produced by in vivo cyanobacterial sheath calcification in stromatolites of the ca. 1200 Ma Society Cliffs Formation, Baffin and Bylot Islands, Arctic

An Early-Branching Microbialite Cyanobacterium Forms Intracellular Carbonates

A cyanobacterium in modern microbialites in Lake Alchichica (Mexico) that forms intracellular amorphous calcium-magnesium-strontium-barium carbonate inclusions about 270 nanometers in average diameter is identified, revealing an unexplored pathway for calcification.

Photosynthesis‐controlled calcification in a hypersaline microbial mat

Calcium carbonate precipitation in the photic zone of these hypersaline mats is primarily controlled by photosynthesisinduced pH and carbonate concentration increases, however, heterotrophic bacteria play an important complementary role in calcification because they maintain high concentrations of DIC in the mat pore water.

Calcifying Cyanobacteria - 2 The potential of biomineralization for Carbon Capture and Storage

A better understanding of the biochemical and genetic mechanisms that carry out and regulate cynaobacterial biomineralization should put us in a position where the authors can further optimize these steps by exploiting the powerful techniques of genetic engineering, directed evolution, and biomimetics.

An atmospheric stimulus for cyanobacterial-bioinduced calcification ca. 350 million years ago?

  • R. Riding
  • Environmental Science, Geography
  • 2009
Cyanobacterial calcification is promoted by CO2-concentrating mechanisms developed in response to photosynthetic carbon limitation, and the induction of cyanobacterial CCMs, triggered by Late Devonian change to a relatively low CO2 and high O2 atmosphere, has probably persisted to the present day, but well-developed calcification in marine cyanobacteria has been restricted to intervals of elevated carbonate saturation state.
