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
