Abstract

Microbial CO2 capture coupled with biosurfactant production represents a promising strategy for greenhouse gas mitigation and sustainable biomanufacturing. This review examines the metabolic and engineering aspects of microbial carbon capture, focusing on both anaerobic and CO2-enriched systems within the Microbial-CCUS framework. The structural diversity, physicochemical properties, and industrial applications of microbial biosurfactants are discussed, along with emerging evidence of anaerobic biosurfactant synthesis linked to CO2 metabolism. Advances in genetic and synthetic biology, pathway modularization, and systems-level modeling are reshaping the potential to coordinate CO2 fixation with biosurfactant biosynthesis. Integrating artificial intelligence with metabolic engineering may further optimize productivity, scalability, and energy efficiency. Despite technical and economic challenges, the convergence of CO2 utilization, biotechnology, and digital innovation offers a transformative route toward circular carbon systems and climate mitigation.

Key points

• Microbial CO2 capture drives biosurfactant synthesis within Microbial-CCUS systems.

• Anaerobic and CO2-enriched cultures unlock new routes for sustainable biomanufacturing.

• Synthetic biology links carbon-fixation modules to biosurfactant pathways.
