LA BIOMINERALIZACIÓN COMO HERRAMIENTA CONTRA EL CAMBIO CLIMÁTICO
Abstract
Microbial biomineralization represents a promising and innovative approach to reducing atmospheric carbon dioxide (CO2) levels. This natural process is widely observed in various organisms capable of utilizing environmental CO2 to mineralize it into carbonates, forming biominerals such as shells, spicules, and, in the case of microbes, structures like stromatolites. In this context, microbially induced biomineralization has emerged as a biotechnological strategy for CO2 capture and storage. This method offers an energy-efficient alternative to physicochemical technologies, using bacterial enzymatic and metabolic activities to convert CO2 into stable minerals that can be applied in various engineering solutions, including self-healing concrete, heavy metal removal, and soil stabilization. These applications highlight the versatility of biomineralizing microbes in promoting carbon neutrality and mitigating emissions. This promising biotechnology addresses climate change, supports net-zero emissions targets, and fosters community sustainability.
