Resumo
Biomineralization is a chemical change in environment through the microbial activity
that results in the precipitation of minerals, being a phenomenon widely spread in
nature. In microbially induced carbonate precipitation (MICP), ureases plays an
important role in hydrolyzing urea by a large variety of microorganisms capable of
producing high levels of this enzyme. There are different polymorphs of calcium
carbonate crystal and the structure that is formed depends on the type of calcium
used, the incubation time and metabolic activities of the evaluated microbrial species. MICP is a promising and environmentally friendly alternative to current and
conventional remediation technologies capable of solving environmental problems in
multidisciplinary fields. Several applications such as increased quality and improved
properties of building materials, removal of potentially toxic metals and
radionucleotides and sequestration of atmospheric carbon dioxide have been
discussed.
