Abstract：The steel industry plays a pivotal role in economic development. However, it stands as a significant contributor to large-scale CO2 emissions. Based on the backdrop of global climate change, it is imperative and urgent to reduce CO2 emissions to alleviate global climate changes and strive for sustainable development. Genetically engineered bacteria exhibit a remarkable capacity to assimilate CO2 via regulation of genes of interest, rational design of metabolic pathways, and optimization of bioprocesses. They allow the upcycling of CO2 into high-value-added products, such as organic acids, biofuels, and polyols, offering an innovative solution for the transitioning from the linear “acquisition-manufacturing-processing” economy to a circular economy with diminished carbon footprints. Consequently, this study highlights the research advancements concerning the microbial fixation/conversion of CO2 derived from steel off-gas. This review systematically summarizes the theoretical frontiers and engineering challenges and emphasizes the pivotal role of gene editing technology. The advancements in this field not only provide a new avenue for the reduction of CO2 emission and environmental protection but also pave a path with future innovations towards the attainment of sustainable development goals.
