Effect of Roughage Source on the Composition and Colonization of Rumen Bacteria and Methanogens in Dumont and Mongolian Sheep [PDF]

Animals
Understanding the influence of the sheep breed and roughage source on the composition of rumen bacteria and methanogens is essential for optimizing roughage efficiency. The experiment employed a 2 × 2 factorial design.

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.

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 ...

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.

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.

3D‐Printed Methane‐Producing Electrodes for Microbial Fuel Cells Developed Using Biogel Ink Containing Live Methanogens and White Charcoal

Macromolecular Materials and Engineering, 2023
Methanogens are used as catalysts for cathodes in microbial fuel cells, to reduce CO2 to CH4. However, the attachment of microbes to the electrodes via culturing is time‐consuming, and inadequate biofilm formation can lead to lesser surface area coverage,

Novel Methanobacterium Strain Induces Severe Corrosion by Retrieving Electrons from Fe⁰ under a Freshwater Environment

Microorganisms, 2022
Methanogens capable of accepting electrons from Fe0 cause severe corrosion in anoxic conditions. In previous studies, all iron-corrosive methanogenic isolates were obtained from marine environments.
