Biogas produced from organic wastes contains energetically usable methane and
unavoidable amount of carbon dioxide. The exploitation of whole biogas energy is locally …

Methyl-based methanogenesis is one of three broad categories of archaeal anaerobic
methanogenesis, including both the methyl dismutation (methylotrophic) pathway and the …

Uncovers the Key Role Microbes Play in the Transformation of Oxidizable and Reducible
MineralsMany areas of geomicrobial processes are receiving serious attention from …

Methane is the second most important greenhouse gas on earth. It is produced by
methanogenic archaea, which play an important role in the global carbon cycle. Three main …

Marine coastlines colonized by seagrasses are a net source of methane to the atmosphere.
However, methane emissions from these environments are still poorly constrained, and the …

Highlights•The methanogens consist of the hydrogenotrophs and the methylotrophs.•The
methanogens are metabolically more versatile than previously appreciated.•Alternative …

It is now clear that active methanogens are present in the deep-subsurface. This paper
reviews microbial population structures and the biodegradation of organic compounds to …

Members of the archaeal order Methanomassiliicoccales are methanogens mainly
associated with animal digestive tracts. However, environmental members remain poorly …

Hydraulic fracturing is one of the industrial processes behind the surging natural gas output
in the United States. This technology inadvertently creates an engineered microbial …

Archaea are widespread in marine sediments, but their occurrence and relationship with
natural salinity gradients in estuarine sediments is not well understood. This study …
