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

Methanosarcina mazei strain 1.F.A.1B.3 is a methanogenic archaeon characterized by its cocci shape and anaerobic metabolism. This organism is a lithotroph, meaning it derives energy from inorganic compounds, which is essential for its survival in diverse habitats. It does not exhibit mobility, as it lacks flagella, although flagella presence is noted. Strain 1.F.A.1B.3 thrives optimally at a temperature of 30°C, placing it within the mesophilic temperature range. Its cellular structure is notable for having a single replicon and one membrane, which is characteristic of many archaea. The strain is nonsporulating, indicating that it does not form spores as a means of survival under unfavorable environmental conditions. As a free-living organism, Methanosarcina mazei strain 1.F.A.1B.3 plays a crucial role in its ecological niche, particularly in anaerobic environments where it contributes to the biogeochemical cycling of carbon. By facilitating the conversion of organic matter to methane, this strain is significant in methane production processes, which have implications for energy generation and greenhouse gas emissions. The accession number for this strain is JJQB00000000.1, which provides a reference point for further genomic studies. Overall, Methanosarcina mazei strain 1.F.A.1B.3 exemplifies the complex interactions within anaerobic ecosystems and highlights the importance of methanogens in global carbon cycling.
