Characterisation of CaCO3 phases during strain-specific
We have studied microbial induced calcium carbonate (CaCO3) precipitation (MICP) in three ureolytic bacterial strains from the Sporosarcina family, The below table (Table 1) shows the pathways followed by different bacteria and the reactions which they undergo to precipitate calcium carbonate. Different pathways produce different by-products.

Calcite Nanocrystal Production Using Locally Isolated
Microbially induced calcium carbonate precipitation (MICP) is an abundant process in nature and involves the microorganism's activities. Therefore, our aim was to characterize the crystals precipitated by locally isolated urease-producing bacteria (Sporosarcina pasteurii N4, Lysinibacillus boronitolerance N6, Bacillus sp. N2, and The formation of calcium and magnesium carbonates has been explained by the production of NH 4 + and CO 2 in presence of calcium and magnesium ionic species. Other authors have These findings explain the greater tendency of these bacterial strains to precipitate calcium carbonate or calcium sulphate and calcium carbonate instead ofBioprecipitation of Calcium Carbonate Crystals by Bacteria

Carbonate ions from ureolysis react with calcium ions (Ca +2) to precipitate calcium carbonate (CaCO 3) inside the ground. Hydrolysis of urea occurs spontaneously in water at a very slow rate, but the reaction kinetics is sped up by a factor of 10 14 when the urease enzyme is used as a catalyst .

Abstract and Figures. Bacteria with ureasic activity are microorganisms found in soil that in presence of urea and calcium, they can produce calcium carbonate, a process known as microbiologically2.1. Ureolytic-Induced Carbonate Precipitation (UICP) Ground stabilization by ureolytic calcification relies on the dissociation of urea (CH 4 N 2 O) into ammonium (NH 4 +) and carbonate ions (CO 3 2−) by the urease enzyme, which acts as a reaction catalyst.Carbonate ions from ureolysis react with calcium ions (Ca +2) to precipitate Advances in Enzyme Induced Carbonate Precipitation and

Phase and morphology of calcium carbonate precipitated by
1. Introduction Calcium carbonate (CaCO 3), one of the most common minerals, is naturally produced during the mineralization of marine organisms over millions of years and constitutes almost 4% of the crust of Earth. 1 In addition, CaCO 3 is involved in the global carbon cycle, affecting the chemistry of the oceans and the climate on Earth, and its Biodeposition of minerals is a widespread phenomenon in the biological world and is mediated by bacteria, fungi, protists, and plants. Calcium carbonate is one of those minerals that naturally precipitate as a by-product of microbial metabolic activities.

The vast majority of carbonate minerals in modern marine sediments are biogenic, derived from the skeletal remains of organisms living in the ocean. However, carbonate minerals can also precipitate abiotically within marine sediments, and this carbonate mineral precipitation within sediments has been suggested as a third major, Concurrent calcium carbonate precipitations in the cyanobacteria bloom region are between 0.9 × 108 and 2.6 × 108 mol per month. of CO2 influx were used for the production of biomassCyanobacteria blooms induced precipitation of calcium carbonate
