The elevated level of carbon dioxide in the atmosphere has become a pressing concern for environmental health due to its contribution to climate change and global warming. Simultaneously, the energy crisis is a significant issue for both developed and developing nations. In response to these challenges, carbon capture, sequestration, and utilization (CCSU) have emerged as promising solutions within the carbon-neutral bioenergy sector. Numerous technologies are available for CCSU including physical, chemical, and biological routes. The aim of this study is to explore the potential of CCSU technologies, specifically focusing on the use of microorganisms based on their well-established metabolic part. By investigating these biological pathways, we aim to develop sustainable strategies for climate management and biofuel production. One of the key novelties of this study lies in the utilization of microorganisms for CO fixation and conversion, offering a renewable and efficient method for addressing carbon emissions. Algae, with its high growth rate and lipid contents, exhibits CO fixation capabilities during photosynthesis. Similarly, methanogens have shown efficiency in converting CO to methane by methanogenesis, offering a viable pathway for carbon sequestration and energy production. In conclusion, our study highlights the importance of exploring biological pathways, which significantly reduce carbon emissions and move towards a more environmentally friendly future. The output of this review highlights the significant potential of CCSU models for future sustainability. Furthermore, this review has been intensified in the current agenda for reduction of CO at considerable extends with biofuel upgrading by the microbial-shift reaction.
大气中二氧化碳水平的升高，由于其对气候变化和全球变暖的贡献，已成为环境健康的一个紧迫问题。与此同时，能源危机是发达国家和发展中国家共同面临的重大问题。为应对这些挑战，碳捕集、封存和利用（CCSU）在碳中性生物能源领域已经成为有前途的解决方案。CCSU 有许多技术，包括物理、化学和生物途径。本研究旨在探索 CCSU 技术的潜力，特别是关注基于其成熟代谢部分的微生物利用。通过研究这些生物途径，我们旨在开发用于气候管理和生物燃料生产的可持续策略。本研究的一个关键新颖之处在于利用微生物进行 CO 固定和转化，为解决碳排放提供了一种可再生和高效的方法。藻类具有较高的生长速度和脂质含量，在光合作用过程中具有 CO 固定能力。同样，产甲烷菌在产甲烷过程中也表现出将 CO 转化为甲烷的效率，为碳封存和能源生产提供了可行的途径。总之，本研究强调了探索生物途径的重要性，这显著减少了碳排放，朝着更环保的未来迈进。本综述的结果突出了 CCSU 模型对未来可持续性的重要潜力。此外，本综述还在当前议程中得到了加强，即在微生物移位反应的基础上，通过生物燃料升级，以相当大的幅度减少 CO。
