Abstract
Microbially induced carbonate precipitation (MICP) technology has shown promising results in civil engineering in improving compressive strength, durability, and self-healing of building materials. A variety of microbes are able to utilize CO2 through several CO2 assimilation pathways and convert CO2 into value-added chemicals, or induce CaCO3 precipitation. In the present review, the role of microbes and their enzymes involved in CO2 sequestration, microbial routes in CaCO3 formation, biocementation, and the effectiveness of MICP in improving durability of building materials is discussed. An emphasis has been paid on the potential of cyanobacteria in biocementation. Furthermore, recommendations to employ the MICP technology at commercial scale and reduction in cost of application are provided in this review.
