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

Methanosarcina mazei strain 3.F.A.1B.1 is a free-living anaerobic archaeon characterized by its cocci shape and lithotrophic energy metabolism. This strain thrives in multiple habitats, indicating a versatile ecological niche. It does not exhibit mobility, which is typical for many members of this genus, and possesses flagella, although it does not utilize them for movement. The optimal growth temperature for Methanosarcina mazei strain 3.F.A.1B.1 is 30°C, placing it within the mesophilic temperature range. This suggests that it is well adapted to environments that are neither too hot nor too cold, potentially including organic-rich sediments or anaerobic digesters where temperatures remain stable. With only one replicon and one membrane, this strain exhibits a relatively simple genomic and cellular structure, which may contribute to its efficient metabolic processes. Importantly, Methanosarcina mazei strain 3.F.A.1B.1 does not form spores, indicating a lifestyle that relies on consistent environmental conditions for growth and survival. From a biological and ecological perspective, the ability of Methanosarcina mazei strain 3.F.A.1B.1 to utilize inorganic compounds for energy in anaerobic conditions plays a critical role in carbon cycling within its habitat. This strain contributes to methane production, a significant process in many anaerobic ecosystems, underscoring its importance in both environmental and biotechnological contexts. The accession number for this strain is JJPC00000000.1.
