This study investigates the potential of bioaugmentation with Bacillus species to enhance wastewater treatment and develop a bacterial–CaCO3 system for self-healing cement applications. Utilizing microbiologically induced calcium carbonate precipitation (MICP), this evaluates dual functionality licheniformis B. muralis strains. For treatment, process achieved significant pollutant reductions, including 99.52% decrease in biochemical oxygen demand (BOD5), 92.13% reduction chemical (COD), substantial removal heavy metals nutrients. also produced high concentrations CaCO3 precipitate enriched viable bacterial cells, demonstrating an eco-friendly approach improving water quality. applications, bioaugmented crystals were coated nutrient sodium silicate layers form coupled system. demonstrated 92% recovery compressive strength after 180 days, highlighting its ability autonomously repair microcracks cement-based materials. The layered encapsulation strategy ensured viability controlled activation mechanism, offering scalable sustainable solution infrastructure resilience. dual-function addresses critical environmental construction challenges by linking efficient innovative material development, contributing global sustainability circular economy goals.
