Abstract
A large amount of anthropogenic CO2 emissions are derived from Portland cement production, contributing to global warming, which threatens human health and exposes flora and fauna to ecological imbalance. With concerns about the high maintenance and repair costs of concrete, the development of microbially induced calcium carbonate precipitation (MICP)-based self-healing concrete has been extensively examined. Bacterial carriers for microcrack healing could enhance the concrete’s self-healing capacity by maintaining bacterial activity and viability. To reduce cement consumption, the development of sustainable engineered living materials (ELMs) based on MICP has become a promising new research topic that combines synthetic biology and material science, and they can potentially serve as alternatives to traditional construction materials. This review aims to describe bacterial carriers and the ongoing development of advanced ELMs based on MICP. We also highlight the emerging issues linked to applying MICP technology at the commercial scale, including economic challenges and environmental concerns.
期刊介绍:
Bioresource Technology publishes original articles, review articles, case studies, and short communications covering the fundamentals, applications, and management of bioresource technology. The journal seeks to advance and disseminate knowledge across various areas related to biomass, biological waste treatment, bioenergy, biotransformations, bioresource systems analysis, and associated conversion or production technologies.
Topics include:
• Biofuels: liquid and gaseous biofuels production, modeling and economics
• Bioprocesses and bioproducts: biocatalysis and fermentations
• Biomass and feedstocks utilization: bioconversion of agro-industrial residues
• Environmental protection: biological waste treatment
• Thermochemical conversion of biomass: combustion, pyrolysis, gasification, catalysis.
