Microbial-Induced Calcite Precipitation in soils: use of alternative raw materials and analysis of environmental implications
… process that induces the precipitation of calcium carbonate minerals as a result of microbial activity. In MICP via urea hydrolysis, urea, calcium, and simple carbon and nitrogen chemical compounds are supplied to stimulate degradation of urea by ureolytic microorganisms to produce …

Permanence and Life Cycle Performance of Biocementation Soil Improvement
… of granular soils through the generation of calcium carbonate minerals on soil particles surfaces and at interparticle contacts. The process can offer an environmentally beneficial alternative to conventional ground improvement methods, which have traditionally relied on energy-intensive …

Establishing a physical and chemical framework for Amorphous Calcium Carbonate (ACC) biomineralization
… that involve metastable intermediates. Biogenic calcium carbonate minerals are now recognized to develop by aggregating molecules or clusters to form amorphous phases that later transform to one or more crystalline polymorphs. Amorphous calcium carbonate (ACC) is now recognized as a precursor to …

The formation of carbonate minerals in laboratory and environmental settings
… processes driving the formation of sedimentary carbonate minerals. While some work has been done exploring the formation of carbonate minerals via microbial sulfate reduction, less attention has been given to the detailed processes involved in this microbially induced carbonate mineral formation …

Water Column Productivity, Calcite Precipitation, and Phosphorus Dynamics in Freshwater Marshes
… can increase pH enough to cause precipitation of calcium carbonate minerals. During the precipitation of calcite (CaCO3) other chemical species such as phosphorus (P) can sorb onto the newly forming crystals and thus be removed from thewater column. While calcite precipitation and subsequent P …
