Why ureolytic bacteria use urea? And why they produce CaCO3?

Due to urease activity, bacteria are able to use urea as a sole nitrogen source and produce ammonia, which increases the pH in the proximal environment, causing Ca2+ and CO32- to precipitate as CaCO3.

Ureolytic bacteria hydrolyze urea to generate ATP by the efflux of ammonium ions through ATP-synthase, producing carbonate. In the presence of calcium ions in excess, calcium carbonate will precipitate. biocementation conditions which are reported in the literature for the production of CaCO 3 .

nucleic acid molecules are incredibly complex, containing the code that guarantees the four different nucleotide units comprise dna, the nucleic acid of interest to the genealogist. and one of four nitrogen-containing molecules called nucleotides
