Novel methylotrophic bacteria isolated from the River Thames (London, UK) [PDF]

open access: yes, 2008
Enrichment and elective culture for methylotrophs from sediment of the River Thames in central London yielded a diversity of pure cultures representing several genera of Gram-negative and Gram-positive bacteria, which were mainly of organisms not ...

Halophilic Methylotrophic Methanogens May Contribute to the High Ammonium Concentrations Found in Shale Oil and Shale Gas Reservoirs

open access: yesFrontiers in Energy Research, 2019
Flow-back and produced waters from shale gas and shale oil fields contain high ammonium, which can be formed by methanogenic degradation of methylamines into methane and ammonium. Methylamines are added to fracturing fluid to prevent clay swelling or can

Zwitterionic cellular polymer enabled reductive fixation of CO2 for N-methylation of amines

open access: yesGreen Synthesis and Catalysis, 2023
Using heterogeneous catalysts to promote the construction of the C–N bond between amines and CO2 under mild conditions is a challenge yet. Herein, we synthesized a novel zwitterionic polymer (PDDC) with a cellular structure via self-complexation of ...

Diet-induced metabolic changes of the human gut microbiome: importance of short-chain fatty acids, methylamines and indoles

open access: yesActa Diabetologica, 2019
The human gut is a home for more than 100 trillion bacteria, far more than all other microbial populations resident on the body’s surface. The human gut microbiome is considered as a microbial organ symbiotically operating within the host.

Selenocysteine, pyrrolysine and the unique energy metabolism of methanogenic archaea [PDF]

open access: yes, 2010
Methanogenic archaea are a group of strictly anaerobic microorganisms characterized by their strict dependence on the process of methanogenesis for energy conservation.

Designing zeolite catalysts for shape-selective reactions: Chemical modification of surfaces for improved selectivity to dimethylamine in synthesis from methanol and ammonia [PDF]

open access: yes, 1990
The relative contributions of external and intracrystalline acidic sites of small pore H-RHO zeolite for the selective synthesis of methylamines from methanol and ammonia have been studied.

Metabolic flexibility as a major predictor of spatial distribution in microbial communities [PDF]

open access: yes, 2014
A better understand the ecology of microbes and their role in the global ecosystem could be achieved if traditional ecological theories can be applied to microbes. In ecology organisms are defined as specialists or generalists according to the breadth of

Occurrence and expression of genes encoding methyl-compound production in rumen bacteria

open access: yesAnimal Microbiome, 2019
Background Digestive processes in the rumen lead to the release of methyl-compounds, mainly methanol and methylamines, which are used by methyltrophic methanogens to form methane, an important agricultural greenhouse gas.
