Methanosarcina mazei strain 1.H.A.2.1

Methanosarcina mazei strain 1.H.A.2.1 is a nonsporulating, coccoid archaeon that optimally thrives at a temperature of 30.0°C. This organism is classified as a lithotroph, deriving its energy from inorganic compounds, which allows it to play a significant role in biogeochemical cycles, particularly in anaerobic environments. Methanosarcina mazei strain 1.H.A.2.1 is strictly anaerobic, meaning it cannot survive in the presence of oxygen, and it occupies diverse habitats where anaerobic conditions prevail. The strain's coccoid shape may confer advantages in its ecological niches, potentially enhancing its ability to aggregate or form biofilms in sediment or other anaerobic substrates. Given its lithotrophic metabolism, Methanosarcina mazei strain 1.H.A.2.1 likely contributes to methane production in various habitats, including wetlands, sediments, and other environments rich in organic matter. This metabolic capacity is crucial for understanding the role of methanogenic archaea in carbon cycling and their potential implications for greenhouse gas emissions in anaerobic ecosystems. The adaptability of this strain to multiple habitats underscores the ecological versatility of methanogens and their importance in anaerobic microbial communities.
