Detection and quantification of rumen methanogens using F420 autofluorescence profiling with spectral flow cytometry [PDF]
Applied and Environmental MicrobiologyMethanogenic archaea that reside in the rumen of sheep, cattle, and other ruminants generate 16% of global emissions of methane, a potent greenhouse gas. The majority of rumen methanogens belong to species that display readily observable autofluorescence

Genomic Characterization of Methanomicrobiales Reveals Three Classes of Methanogens [PDF]
PLoS ONE, 2009 BACKGROUND:Methanomicrobiales is the least studied order of methanogens. While these organisms appear to be more closely related to the Methanosarcinales in ribosomal-based phylogenetic analyses, they are metabolically more similar to Class I methanogens.

Gene Order Phylogeny and the Evolution of Methanogens
PLoS ONE, 2009 Methanogens are a phylogenetically diverse group belonging to Euryarchaeota. Previously, phylogenetic approaches using large datasets revealed that methanogens can be grouped into two classes, "Class I" and "Class II".

Microorganisms, 2021 Anaerobic fungi in the digestive tract of herbivores are one of the critical types of fiber-degrading microorganisms present in the rumen. They degrade lignocellulosic materials using unique rhizoid structures and a diverse range of fiber-degrading ...

Prebiotic aqueous reactions catalyzed by native nickel without hydrogen. [PDF]
FEBS JSerpentinizing (H2‐producing) hydrothermal vents are candidate environments for metabolic origin. They generate highly reducing conditions that convert CO2 to formate and methane in abiotic reactions resembling reactions of the acetyl‐CoA pathway of CO2 fixation. They also contain natural catalysts. Native nickel (Ni0), like Fe0, Co0, and their alloys,

Codh/Acs-Deficient Methanogens Are Prevalent in Anaerobic Digesters
Microorganisms, 2021 Methanogens are archaea that grow by producing methane as a catabolic end product and thrive in diverse anaerobic habitats, including soil, sediments, oil reservoirs, digestive tracts, and anaerobic digesters.

Using metagenomics tool to evaluate the enrichment efficiency of methanogens in marine sediment in Truong Sa archipelage, Khanh Hoa province, Vietnam [PDF]
E3S Web of Conferences, 2023 Methanogens (archaea bacteria that produce methan) play an important role in the anaerobic digestion of organic waste, however, in marine environment, the low density of methanogens makes anaerobic digestion very slow.
