This article discusses this process and its mechanism, as well as bacterial urease, calcium carbonate crystals formed, and factors that affect the efficiency of MICP, as type of bacteria, bacterial cell concentrations, pH, temperature and calcium and urea concentrations. In addition, applications as removal of heavy metals in water, bioconsolidation, biocement and CO2 sequestration are also discussed. 2018 artículo científico 0120-2812 https://www.redalyc.org/articulo.oa?id=169959151012 https://www.redalyc.org/journal/1699/169959151012/ https://www.redalyc.org/journal/1699/169959151012/html/ https://www.redalyc.org/journal/1699/169959151012/169959151012.epub https://www.redalyc.org/journal/1699/169959151012/movil 10.15446/acag.v67n2.66109 en http://www.redalyc.org/revista.oa?id=1699 Acta Agronómica application/pdf Universidad Nacional de Colombia Acta Agronómica (Colombia) Num.2 Vol.67 |
