Comparison of Different Carbon Sources on Biomethane Production with Clostridium cellulovorans and Methanogens

Applied Microbiology, 2023
Methane (CH4) has attracted attention as not only one of the hydrogen carriers in terms of energy density, but also synthetic natural gas. In nature, the decomposition of organic compounds is performed with bacterial ecosystems that can produce CH4 ...

Taxonomy and Halotolerance of Mesophilic Methanosarcina Strains, Assignment of Strains to Species, and Synonymy of Methanosarcina mazei and Methanosarcina frisia [PDF]

International Journal of Systematic Bacteriology, 1992
We examined 22 previously described and newly isolated Methanosarcina strains by performing denaturing gel electrophoresis of whole-cell proteins and assigned these strains to previously described species. Methanosarcina mazei S-6T (T = type strain) and Methanosarcina frisia C 16T were very similar in terms of the electrophoresis patterns of their ...

Characterization of Methanosarcina barkeri MST and 227, Methanosarcina mazei S-6T, and Methanosarcina vacuolata Z-761T [PDF]

International Journal of Systematic Bacteriology, 1991
Members of the genus Methanosarcina are recognized as major aceticlastic methanogens, and several species which thrive in low-salt, pH-neutral culture medium at mesophilic temperatures have been described. However, the environmental conditions which support the fastest growth of these species (Methanosarcina barkeri MST [T = type strain] and 227 ...

Gut archaea associated with bacteria colonization and succession during piglet weaning transitions

BMC Veterinary Research, 2022
Background Host-associated gut microbial communities are key players in shaping the fitness and health of animals. However, most current studies have focused on the gut bacteria, neglecting important gut fungal and archaeal components of these ...

Transfer of Methanococcus frisius to the Genus Methanosarcina as Methanosarcina frisia comb. nov. [PDF]

International Journal of Systematic Bacteriology, 1989
Several methanogenic bacteria that utilize methanol, acetate, or methylamines have been isolated from marine habitats, including Methanococcus frisius. However, the 1984 description by Mah and Kuhn of the genus Methanococcus excludes methylotrophic methanebacteria such as Methanococcus frisius.

Molecular characterization of microorganisms with industrial potential for methane production in sludge from Kangemi sewage treatment plant, Nyeri county–Kenya

Heliyon, 2023
Microbial consortia under anaerobic conditions are involved in oxidizing organic matter in the sludge to produce methane gas. However, in developing countries like Kenya, these microbes have not been fully identified to target them for the efficient ...

Conductive Particles Enable Syntrophic Acetate Oxidation between Geobacter and Methanosarcina from Coastal Sediments

mBio, 2018
Coastal sediments are rich in conductive particles, possibly affecting microbial processes for which acetate is a central intermediate. In the methanogenic zone, acetate is consumed by methanogens and/or syntrophic acetate-oxidizing (SAO) consortia.

Insights into pyrrolysine function from structures of a trimethylamine methyltransferase and its corrinoid protein complex

Communications Biology, 2023
Structures of Methanosarcina barkeri trimethylamine methyltransferase (MttB) with its substrates reveal the role of pyrrolysine in methyl group transfer from trimethylamine to the corrinoid cofactor in MttC.

Acetate assimilation pathway of Methanosarcina barkeri [PDF]

Journal of Bacteriology, 1979
The pathway of acetate assimilation in Methanosarcina barkeri was determined from analysis of the position of label in alanine, aspartate, and glutamate formed in cells grown in the presence of [14C]acetate and by measurement of enzyme activities in cell extracts.

Studies on an acetate-fermenting strain of Methanosarcina [PDF]

Applied and Environmental Microbiology, 1978
An acetate-fermenting strain of Methanosarcina was isolated from an acetate enrichment culture inoculated with anaerobic sludge from a waste treatment digestor. In pure culture, this organism fermented acetate in the absence of added hydrogen at rates comparable in magnitude to those found in digestor systems.
