Methanosarcina mazei strain 3.H.M.2.7

Methanosarcina mazei strain 3.H.M.2.7 is a free-living, anaerobic microorganism classified as a lithotroph. This strain exhibits a cocci shape and lacks mobility, meaning it does not possess flagella for movement. It has a single membrane and a single replicon, characteristic of many archaea. The optimal growth temperature for Methanosarcina mazei strain 3.H.M.2.7 is 30°C, placing it within the mesophilic temperature range. This suggests that the organism thrives in moderate temperature environments, which can be found in various habitats. As an anaerobe, this strain does not require oxygen for growth, aligning with its lithotrophic energy source, indicating it likely utilizes inorganic compounds for energy. The absence of sporulation implies that this strain does not form spores, which may affect its survival strategy in fluctuating environmental conditions. In conclusion, the traits of Methanosarcina mazei strain 3.H.M.2.7 illustrate its role as a specialized anaerobic microorganism capable of thriving in diverse habitats through lithotrophic metabolism. Its adaptation to mesophilic conditions and free-living lifestyle may contribute significantly to biogeochemical cycles, particularly in environments rich in organic matter where anaerobic processes are prevalent.
