Methanosarcina mazei strain 3.F.A.1A.3

Methanosarcina mazei strain 3.F.A.1A.3 is a coccoid, anaerobic archaeon that thrives in multiple habitats. As a lithotroph, it derives energy from inorganic sources, adapting to environments where organic substrates may be limited. This strain is classified as mesophilic, with an optimal growth temperature of 30°C, indicating its preference for moderate temperature ranges. The organism has a single replicon and a single membrane, characteristic of many Archaea. Unlike some microorganisms, Methanosarcina mazei strain 3.F.A.1A.3 does not possess flagella and is non-motile, suggesting it relies on passive transport mechanisms or environmental currents for nutrient acquisition. Additionally, the strain is free-living and does not engage in sporulation, which may limit its resilience to extreme conditions but allows it to thrive in stable anaerobic environments. The ecological role of Methanosarcina mazei strain 3.F.A.1A.3 is significant, particularly in anaerobic ecosystems where it contributes to the biogeochemical cycling of carbon. As a lithotrophic anaerobe, it likely plays a vital part in methane production, utilizing carbon dioxide and hydrogen in its metabolic processes. The presence of this strain in diverse habitats highlights its adaptability and importance in maintaining ecological balance within anaerobic environments. Accessions for this strain are available under JJPB00000000.1, providing a resource for further research into its metabolic pathways and ecological impacts.
