Five strains of methanogenic archaea (MT, MS, MM, MSP, ZB) were isolated from permanently and periodically cold terrestrial habitats. Physiological and morphological studies, as well as phylogenetic analyses of the new isolates were performed. Based on sequences of the 16S rRNA and methyl-coenzyme M reductase a-subunit (mcrA) genes all new isolates are closely related to known mesophilic and psychrotolerant methanogens. Both, phylogenetic analyses and phenotypic properties allow to classify… Expand
Methanobacterium aarhusense sp. nov., a novel methanogen isolated from a marine sediment (Aarhus Bay, Denmark).
TLDR
Based on 16S rRNA gene sequence analysis, the isolate is proposed to represent a novel taxon within the genus Methanobacterium, namely MethanOBacterium aarhusense sp. Expand
Aceticlastic and NaCl-Requiring Methanogen “Methanosaeta pelagica” sp. nov., Isolated from Marine Tidal Flat Sediment
TLDR
The number of Methanosaeta organisms increased with increasing depth and was much higher than that of Methanosarcina organisms, suggesting that aceticlastic methanogens contribute to acetate metabolism to a greater extent than previously thought in marine environments, where sulfate-reducing acetate oxidation prevails.

TLDR
Two methane-producing archaea, designated Mic5c12(T) and Mic6c05(T), were isolated from sludge deposited in a crude oil storage tank and a tubercle on the interior of a pipe transporting natural gas-containing brine, respectively and revealed that they belonged to the genus Methanobacterium. Expand
Methanobacterium aggregans sp. nov., a hydrogenotrophic methanogenic archaeon isolated from an anaerobic digester.
TLDR
A novel, strictly anaerobic, hydrogenotrophic methanogen, strain E09F.3T, which was isolated from a commercial biogas plant in Germany and was closely related to Methanobacterium congolense CT but morphological, physiological and genomic characteristics indicated that it represents a novel species. Expand
Methanomethylovorans uponensis sp. nov., a methylotrophic methanogen isolated from wetland sediment
TLDR
A novel mesophilic, methylotrophic, methanogenic archaeon, designated strain EK1T, was enriched and isolated from wetland sediment and represents a novel species belonging to the genus Methanomethylovorans, for which the name Methanoreensis sp. Expand
Methanospirillum lacunae sp. nov., a methane-producing archaeon isolated from a puddly soil, and emended descriptions of the genus Methanospirillum and Methanospirillum hungatei.
TLDR
On the basis of its phenotypic characteristics and phylogenetic position, strain Ki8-1(T) is considered to represent a novel species of the genus Methanospirillum, for which the name Methan Hospicellum lacunae sp. Expand
Archaeal communities of Arctic methane-containing permafrost.
TLDR
Investigation of the diversity of methanogenic archaea and their distribution in five permafrost samples collected from a borehole in the Kolyma River Lowland found the greatest diversity of archaea was observed at a depth of 22.3 m, probably due to the availability of the labile organic carbon and/or to the migration of the microbial cells during the freezing front towards the bottom.

Isolation of Uncultivated Methanogens using Anaerobic Syntrophic Substrate-degrading Coculture System.
An anaerobic syntrophic substrate-degrading coculture system was used to isolate uncultivated methanogens that can provide hydrogen at a very low partial pressure. Primary enrichments for methanogensExpand
Methanosarcina flavescens sp. nov., a methanogenic archaeon isolated from a full-scale anaerobic digester.
TLDR
Phenotypic, physiological and genomic characteristics indicated that strain E03.2T represents a novel species of the genus Methanosarcina, for which the name MethanosARCina flavescens sp. Expand
Isolation and characterization of new Methanosarcina mazei strains KOR-3, -4, -5, and -6 from an anaerobic digester using pig slurry
TLDR
Phylogenetic analysis of 16S rRNA and mcrA genes demonstrated that strains KOR-3, -4, -5, and -6 are related to Methanosarcina mazei (M. mazei, 99% sequence similarity); however, chloramphenicol inhibited cell growth. Expand

Methanosarcina lacustris sp. nov., a new psychrotolerant methanogenic archaeon from anoxic lake sediments.
TLDR
Based on the results of physiological and phylogenetic studies strain ZS can be assigned to a new species of the genus Methanasarcina, the name Methanosarcina lacustris sp. Expand
A Methanogenic Archaeon from Ace Lake, Antarctica: Methanococcoides burtonii sp. nov.
TLDR
A methylotrophic, methanogenic bacterium was isolated from the anoxic hypolimnion of Ace Lake, Antarctica, a lake with ionic composition similar to that of seawater, where a new species Methanococcoides burtonii is described and the type strain is DSM 6242. Expand

TLDR
It is proposed that strain DMS1T is a representative of a novel genus which was directly enriched and isolated from a freshwater sediment in defined minimal medium containing dimethyl sulfide as the sole carbon and energy source and was named Methanomethylovorans hollandica. Expand
Preliminary observations on psychrotrophic and psychrophilic, heterotrophic bacteria from antarctic water samples
TLDR
Identification of 93 isolates showed the majority to be Pseudomonas (82%), with Flavobacterium and Moraxella representing 13% of the isolates, and this strain may represent a new taxon of curved, gram negative bacteria. Expand
Diversity and Taxonomy of Methanogens
TLDR
This work has shown that methane production is a ubiquitous, defining characteristic of methanogens, a group of microbes that is phylogenetically distinct from eukaryotes and true bacteria. Expand
Molecular analyses of methyl-coenzyme M reductase alpha-subunit (mcrA) genes in rice field soil and enrichment cultures reveal the methanogenic phenotype of a novel archaeal lineage.

A new methanogen-specific fingerprinting assay based on terminal restriction fragment length polymorphism (T-RFLP) analysis of fluorescently labelled polymerase chain reaction (PCR) products allowed us to distinguish all environmental mcrA/mrtA sequences via group-specific Sau96I restriction sites.

Examination of Antarctic prokaryotic diversity through molecular comparisons

Use of the 16S rRNA gene as a molecular clock would suggest that the majority of Antarctic prokaryotes diverged from their nearest known non-Antarctic relatives long before a stable ice-sheet developed in Antarctica. Expand

Kinetic analysis of the results confirmed the prevalence of hydrogen acetogenesis on methanogenesis, and accumulation of acetate- and H2/CO2-utilising methanogens should be very important in methanogenic microbial community operating at low temperatures. Expand
