1955 Arch. Biochem. & Biophysics 56 535 The mechanism for methane production from formate in the rumen resembles that for most other methanogenic bacteria.
1968 Jrnl. Bacteriol. 96 2178/1 Occurrence of methane in gas from the human intestine is evidence that methanogenic organisms grow in the human alimentary tract.
1976 Appl. & Environmental Microbiol. 31 99/1 Methanogenic activity in its sediments was first reported in 1932.
1982 M. J. Dring Biol. Marine Plants (1986) ix. 175 Therefore, anaerobic methanogenic bacteria replace those dependent on sulphate, and methane becomes the dominant product of decomposition in old, deep sediments.
1998 Jrnl. Contaminant Hydrol. 34 139 Biotransformation of 1,2-dichloroethane was noted under methanogenic or sulfate reducing conditions in all samples.
