Methanoregula boonei gen. nov., sp. nov., an acidiphilic methanogen isolated from an acidic peat bog.
A novel acidiphilic, hydrogenotrophic methanogen, designated strain 6A8(T), was isolated from an acidic (pH 4.0-4.5) and ombrotrophic (rain-fed) bog located near Ithaca, NY, USA. Cultures were dimorphic, containing thin rods (0.2-0.3 μm in diameter and 0.8-3.0 μm long) and irregular cocci (0.2-0.8 μm in diameter). The culture utilized H(2)/CO(2) to produce methane but did not utilize formate, a...
متن کاملEuropean Bog Bodies: From the Iron Age Peat Bog to the 21st Century
Well preserved bodies dating from the prehistoric era to the 19th century have been found across northwestern Europe; specifically in the peat bogs of Ireland, Great Britain and Denmark. These discoveries were especially prevalent in the late 19th and early 20th centuries when mass peat extraction was at its height. Many of these finds have been dated to the Iron Age and have previously been at...
متن کاملLinksbetweenmethane£uxand transcriptional activitiesof methanogensandmethaneoxidizers ina blanket peat bog
The relationship between biogeochemical process rates and microbial functional activity was investigated by analysis of the transcriptional dynamics of the key functional genes for methanogenesis (methyl coenzyme M reductase; mcrA) and methane oxidation (particulate methane monooxygenase; pmoA) and in situ methane flux at two peat soil field sites with contrasting net methane-emitting and -oxid...
متن کاملIsotope analysis of pyrolysis products from Sphagnum peat and dissolved organic matter from bog water
Elemental analyses (H, N, C, O, S), bulk isotope analyses (C, N) and C content of pyrolysis products from Sphagnum moss, underlying peat from a bog and the bog water (Hohlohsee, Black Forest, Germany) were performed to identify humi®cation processes in the early diagenesis of peat formation and to determine the origin of dissolved organic matter (DOM) in the bog lake. Atomic ratios of bulk elem...
متن کاملThe mcrA gene as an alternative to 16S rRNA in the phylogenetic analysis of methanogen populations in landfill.
Inferred amino acid sequences of the methyl coenzyme-M reductase (mcrA) gene from five different methanogen species were aligned and two regions with a high degree of homology flanking a more variable region were identified. Analysis of the DNA sequences from the conserved regions yielded two degenerate sequences from which a forward primer, a 32-mer, and a reverse primer, a 23-mer, could be de...
