The increase in demand of fossil fuel uses for developmental activity and manufacturing of goods have resulted a huge emission of global warming gases (GWGs) in the atmosphere. Among all GWGs, CO is the major contributor that inevitably causes global warming and climate change. Mitigation strategies like biological CO capture through sequestration and their storage into biological organic form are used to minimize the concentration of atmospheric CO with the goal to control climate change. Since increasing atmospheric CO level supports microbial growth and productivity thus microbial-based CO sequestration has remarkable advantages as compared to plant-based sequestration. This review focuses on CO sequestration mechanism in bacteria through different carbon fixation pathways, involved enzymes, their role in calcite, and other environmentally friendly biomaterials such as biofuel, bioplastic, and biosurfactant.
化石燃料需求的增加用于发展活动和商品制造导致了大量温室气体（GWGs）在大气中的排放。在所有的温室气体中，CO 是主要的贡献者，它不可避免地导致全球变暖与气候变化。生物固碳的封存和储存为生物有机形式的方法被用来将大气中 CO 的浓度最小化，以达到控制气候变化的目的。由于大气中 CO 水平的增加支持微生物的生长和生产力，因此与植物固碳相比，基于微生物的 CO 固存具有显著的优势。这篇综述主要聚焦于细菌通过不同的碳固定途径、相关酶、它们在方解石中的作用以及其他环保生物材料如生物燃料、生物塑料和生物表面活性剂中的 CO 固存机制。
