摘要:

产甲烷古菌是一类严格厌氧微生物类群,能够利用一碳(C1)或二碳(C2)化合物生长并产甲烷,且具有独特的膜脂结构和较好的极端环境耐受能力,因此在CO2等碳资源高值化利用方面展现出底盘细胞潜力。目前,以甲烷八叠球菌属(Methanosarcina)和甲烷球菌属(Methanococcus)为代表的模式产甲烷古菌已逐步建立了穿梭载体、表达调控系统和同源重组、基因编辑技术等遗传改造工具箱。基于此,通过代谢重构和异源代谢途径整合,产甲烷古菌可用于生物合成类异戊二烯、生物塑料等多种非甲烷高值化合物及有机酸和有机醇等小分子平台化合物。从产甲烷古菌的遗传改造工具和高值化合物合成两个方面,系统综述了该领域的研究进展,分析了产甲烷古菌细胞工厂的潜在应用前景,并对未来研究方向进行了展望,以期为产甲烷古菌的合成生物学研究提供参考。

Abstract:

Methanogenic archaea are strictly anaerobic microorganisms capable of utilizing one-carbon (C1) or two-carbon (C2) compounds for growth and methane production. Owing to their unique membrane lipid structures and tolerance to various extreme environmental conditions, they represent promising chassis cells for the high-value conversion of carbon resources such as CO2. To date, genetic engineering toolkits have been progressively established in model methanogens, particularly Methanosarcina and Methanococcus, including shuttle vectors, expression regulation systems, homologous recombination, and gene editing technologies. Leveraging these tools, methanogenic archaea have been metabolically engineered to produce a range of high-value non-methane compounds, including isoprenoids and bioplastics, as well as metabolic intermediates such as organic acids and organic alcohols, through metabolic pathway remodeling and the integration of heterologous metabolic pathways. This review systematically summarized the research progress of genetic engineering tools and high-value compound synthesis in methanogenic archaea, evaluated the application potential of methanogenic archaeal cell factories, and outlined future research directions, which was expected to provide reference for advance synthetic biology research in methanogens.

Key words: methanogens, genetic engineering, synthetic biology, carbon resource utilization
