Cave bacteria-induced amorphous calcium carbonate formation
Amorphous calcium carbonate (ACC) is a precursor of crystalline calcium carbonates that plays a key role in biomineralization and polymorph evolution. Here, we show that several bacterial strains isolated from a Hungarian cave produce ACC and their extracellular polymeric substance (EPS) shields ACC from crystallization. The findings demonstrate that bacteria-produced ACC forms in water-rich environment at room temperature and is stable for at least half year, which is in contrast todoi:10.1038/s41598-020-65667-w pmid:32457467 fatcat:46k7li6hsvgh7mo5qhxibvqvuu
