钢铁工业对发展经济至关重要,但其也是 CO2 大规模排放的重要排放源之一.全球气候变化的背景下,针对 CO2 的减排措施已经成为应对气候变化和实现可持续发展的紧迫任务.通过调控关键基因、改造代谢途径或优化反应条件等方式,获得的工程菌株能够高效同化CO2并转化为有机酸、生物燃料和多元醇等高值产物,为从传统的"获取-制造-处理"经济转变为减少碳足迹的可再生经济提供了新的解决方案.因此,本研究聚焦微生物固定/转化钢铁废气中 CO2 的研究进展,系统性分析了该领域的理论研究前沿和工程应用挑战,探讨了基因编辑技术在其解决方案中的作用.这一领域的探索为未来的碳减排和环境治理提供了全新的视角和路径,对于实现可持续发展目标具有深远意义.
Advances in microbial fixation and conversion mechanisms of carbon dioxide derived from steel off-gas
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.
