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".

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.

Diversity of Methanogens in Animals’ Gut

Microorganisms, 2020
Methanogens are members of anaerobe microbiota of the digestive tract of mammals, including humans. However, the sources, modes of acquisition, and dynamics of digestive tract methanogens remain poorly investigated.

Detection and quantification of rumen methanogens using F420 autofluorescence profiling with spectral flow cytometry [PDF]

Applied and Environmental Microbiology
Methanogenic 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

Interactions between Anaerobic Fungi and Methanogens in the Rumen and Their Biotechnological Potential in Biogas Production from Lignocellulosic Materials

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 ...

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.

Meconial Methanobrevibacter smithii suggests intrauterine methanogen colonization in preterm neonates

Current Research in Microbial Sciences, 2021
To understand the dynamics of methanogens in the human intestinal microbiota, we investigated the presence of methanogens in meconium using a polyphasic approach including microscopy and PCR-sequencing in 33 meconium samples collected from 33 pre-term ...

Effect of short-term warming and drought on the methanogenic communities in degraded peatlands in Zoige Plateau

Frontiers in Microbiology, 2022
Peatlands in Qinghai-Tibetan are degrading with climate change and human activities. Peatland degradation and climate change affect methane emissions. Methanogens are key functional microbes during methane production; however, knowledge of methanogens in

Genomic and transcriptomic insights into methanogenesis potential of novel methanogens from mangrove sediments

Microbiome, 2020
Background Methanogens are crucial to global methane budget and carbon cycling. Methanogens from the phylum Euryarchaeota are currently classified into one class and seven orders, including two novel methanogen taxa, Methanofastidiosa and ...
