Harmful effects on living organisms and the environment are on the rise due to a significant increase in greenhouse gas (GHG) emissions through human activities. Therefore, various research initiatives have been carried out in several directions in relation to the utilization of GHGs via physicochemical or biological routes. An environmentally friendly approach to reduce the burden of significant emissions and their harmful effects is the bioconversion of GHGs, including methane (CH) and carbon dioxide (CO), into value-added products. Methanotrophs have enormous potential for the efficient biotransformation of CH to various bioactive molecules, including biofuels, polyhydroxyalkanoates, and fatty acids. This review highlights the recent developments in methanotroph-based systems for methanol production from GHGs and proposes future perspectives to improve process sustainability via biorefinery approaches.
由于人类活动导致温室气体(GHG)排放量大幅增加,对生物和环境的有害影响正在上升。因此,围绕通过物理化学或生物途径利用温室气体,已经在多个方向开展了各种研究项目。一种减少大量排放及其有害影响负担的环保方法是将包括甲烷(CH)和二氧化碳(CO)在内的温室气体生物转化为增值产品。甲烷营养菌在将CH高效生物转化为各种生物活性分子(包括生物燃料、聚羟基脂肪酸酯和脂肪酸)方面具有巨大潜力。本综述重点介绍了基于甲烷营养菌的温室气体制甲醇系统的最新进展,并提出了通过生物炼制方法提高工艺可持续性的未来展望。
