A unique coral biomineralization pattern has resisted 40 million years of major ocean chemistry change

Today coral reefs are threatened by changes to seawater conditions associated with rapid anthropogenic global climate change. Yet, since the Cenozoic, these organisms have experienced major fluctuations in atmospheric CO2 levels (from greenhouse conditions of high pCO2 in the Eocene to low pCO2 ice-house conditions in the Oligocene-Miocene) and a dramatically changing ocean Mg/Ca ratio. Here we...

Biomineralization induced by Myxobacteria

Myxococcus xanthus is a Gram negative, non-pathogenic, common soil bacterium that belongs to the δsubdivision of the Proteobacteria. According to the data, it is demonstrated that, depending on the chemistry of the culture media, M. xanthus is able to induce the formation of phosphates (struvite, schertelite, newberyite), carbonates (calcite, Mg-calcite, vaterite) and sulfates (barite, taylorit...
