Methylocella silvestris sp. nov., a novel methanotroph isolated from an acidic forest cambisol. (1/20)

Two strains of Gram-negative, aerobic, non-pigmented, non-motile, rod-shaped, methane-oxidizing bacteria were isolated from an acidic forest cambisol near Marburg, Germany, and were designated as strains BL2(T) and A1. These bacteria were morphologically and phenotypically similar to Methylocella palustris K(T). The cells possess a highly specific bipolar appearance. They lack the intracytoplasmic membranes common to all methane-oxidizing bacteria except Methylocella, but contain a vesicular membrane system connected to the cytoplasmic membrane. A soluble methane monooxygenase was present, but no particulate methane monooxygenase could be detected. These bacteria utilize the serine pathway for carbon assimilation. Strains BL2(T) and A1 are moderately acidophilic, mesophilic organisms capable of growth at pH values between 4.5 and 7 (with an optimum at pH 5.5) and at temperatures between 4 and 30 degrees C. Compared with Methylocella palustris K(T), these strains have greater tolerance of cold temperatures, dissolved salts and methanol. On the basis of 16S rRNA gene sequence identity, of species with validly published names, strain BL2(T) is most closely related to Methylocella palustris K(T) (97.3 % identity), Beijerinckia indica subsp. indica ATCC 9039(T) (97.1 %) and Methylocapsa acidiphila B2(T) (96.2 %). The DNA G+C content is 60 mol% and the major phospholipid fatty acid is 18 : 1omega7. Strain BL2(T) showed only 21-22 % DNA-DNA hybridization with Methylocella palustris K(T). The data therefore suggest that strains BL2(T) and A1 represent a novel species of Methylocella; the name Methylocella silvestris sp. nov. is proposed, with strain BL2(T) (=DSM 15510(T)=NCIMB 13906(T)) as the type strain.  (+info)

NifH and NifD phylogenies: an evolutionary basis for understanding nitrogen fixation capabilities of methanotrophic bacteria. (2/20)

The ability to utilize dinitrogen as a nitrogen source is an important phenotypic trait in most currently known methanotrophic bacteria (MB). This trait is especially important for acidophilic MB, which inhabit acidic oligotrophic environments, highly depleted in available nitrogen compounds. Phylogenetically, acidophilic MB are most closely related to heterotrophic dinitrogen-fixing bacteria of the genus BEIJERINCKIA: To further explore the phylogenetic linkage between these metabolically different organisms, the sequences of nifH and nifD gene fragments from acidophilic MB of the genera Methylocella and Methylocapsa, and from representatives of Beijerinckia, were determined. For reference, nifH and nifD sequences were also obtained from some type II MB of the alphaproteobacterial Methylosinus/Methylocystis group and from gammaproteobacterial type I MB. The trees constructed for the inferred amino acid sequences of nifH and nifD were highly congruent. The phylogenetic relationships among MB in the NifH and NifD trees also agreed well with the corresponding 16S rRNA-based phylogeny, except for two distinctive features. First, different methods used for phylogenetic analysis grouped the NifH and NifD sequences of strains of the gammaproteobacterial MB Methylococcus capsulatus within a clade mainly characterized by Alphaproteobacteria, including acidophilic MB and type II MB of the Methylosinus/Methylocystis group. From this and other genomic data from Methylococcus capsulatus Bath, it is proposed that an ancient event of lateral gene transfer was responsible for this aberrant branching. Second, the identity values of NifH and NifD sequences between Methylocapsa acidiphila B2 and representatives of Beijerinckia were clearly higher (98.5 and 96.6 %, respectively) than would be expected from their 16S rRNA-based relationships. Possibly, these two bacteria originated from a common acidophilic dinitrogen-fixing ancestor, and were subject to similar evolutionary pressure with regard to nitrogen acquisition. This interpretation is corroborated by the observation that, in contrast to most other diazotrophs, M. acidiphila B2 and Beijerinckia spp. are capable of active growth on nitrogen-free media under fully aerobic conditions.  (+info)

Methylotrophic autotrophy in Beijerinckia mobilis. (3/20)

Representatives of the genus Beijerinckia are known as heterotrophic, dinitrogen-fixing bacteria which utilize a wide range of multicarbon compounds. Here we show that at least one of the currently known species of this genus, i.e., Beijerinckia mobilis, is also capable of methylotrophic metabolism coupled with the ribulose bisphosphate (RuBP) pathway of C1 assimilation. A complete suite of dehydrogenases commonly involved in the sequential oxidation of methanol via formaldehyde and formate to CO2 was detected in cell extracts of B. mobilis grown on CH3OH. Carbon dioxide produced by oxidation of methanol was further assimilated via the RuBP pathway as evidenced by reasonably high activities of phosphoribulokinase and ribulose-1,5-bisphosphate carboxylase/oxygenase (RubisCO). Detection and partial sequence analysis of genes encoding the large subunits of methanol dehydrogenase (mxaF) and form I RubisCO (cbbL) provided genotypic evidence for methylotrophic autotrophy in B. mobilis.  (+info)

First genome data from uncultured upland soil cluster alpha methanotrophs provide further evidence for a close phylogenetic relationship to Methylocapsa acidiphila B2 and for high-affinity methanotrophy involving particulate methane monooxygenase. (4/20)

Members of upland soil cluster alpha (USC alpha) are assumed to be methanotrophic bacteria (MB) adapted to the trace level of atmospheric methane. So far, these MB have eluded all cultivation attempts. While the 16S rRNA phylogeny of USC alpha members is still not known, phylogenies constructed for the active-site polypeptide (encoded by pmoA) of particulate methane monooxygenase (pMMO) placed USC alpha next to the alphaproteobacterial Methylocapsa acidiphila B2. To assess whether the pmoA tree reflects the evolutionary identity of USC alpha, a 42-kb genomic contig of a USC alpha representative was obtained from acidic forest soil by screening a metagenomic fosmid library of 250,000 clones using pmoA-targeted PCR. For comparison, a 101-kb genomic contig from M. acidiphila was analyzed, including the pmo operon. The following three lines of evidence confirmed a close phylogenetic relationship between USC alpha and M. acidiphila: (i) tetranucleotide frequency patterns of 5-kb genomic subfragments, (ii) annotation and comparative analysis of the genomic fragments against all completely sequenced genomes available in public domain databases, and (iii) three single gene phylogenies constructed using the deduced amino acid sequences of a putative prephenate dehydratase, a staphylococcal-like nuclease, and a putative zinc metalloprotease. A comparative analysis of the pmo operons of USC alpha and M. acidiphila corroborated previous reports that both the pmo operon structure and the predicted secondary structure of deduced pMMO are highly conserved among all MB.  (+info)

A novel species, Methylocella tundrae, is proposed for three methanotrophic strains (T4T, TCh1 and TY1) isolated from acidic Sphagnum tundra peatlands. These strains are aerobic, Gram-negative, non-motile, dinitrogen-fixing rods that possess a soluble methane monooxygenase and utilize the serine pathway for carbon assimilation. Strains T4T, TCh1 and TY1 are moderately acidophilic organisms capable of growth between pH 4.2 and 7.5 (optimum 5.5-6.0) and between 5 and 30 degrees C (optimum 15 degrees C). The major phospholipid fatty acid is 18:1omega7c. The DNA G+C content of strain T4T is 63.3 mol%. The three strains possess almost identical 16S rRNA gene sequences and are most closely related to two previously identified species of Methylocella, Methylocella palustris (97% similarity) and Methylocella silvestris (97.5% similarity). DNA-DNA hybridization values of strain T4T with Methylocella palustris KT and Methylocella silvestris BL2T were respectively 27 and 36%. Thus, the tundra strains represent a

There is a paper in PNAS, Earliest evidence for commensal processes of cat domestication, which raises some interesting questions about the emergence of Felis silvestris catus, the domestic cat. I state questions, because the answers it provides are quite narrow, if plausible. In sum the authors found that ~5,000 years ago a group of cats, possibly Asian wildcats, Felis silvestris ornata, seem to have entered into coexistent relationship with humans. This itself is not entirely surprising. ~10,000 years ago a specimen of Felis silvestris lybica, a Near Eastern wildcat, seems to have been interred at a human grave site on Cyprus. The PNAS paper correctly notes that mitochondrial data also point to Near Easter wildcats has being the wild silvestris group that gave rise to the domestics. Strangely they leave out that autosomal microsatellites, highly variable repetitive regions in the genome, also indicate a clustering of domestic lineages with Near Eastern wildcats (to be clear, this is in the ...

It is believed by some eminent authorities that the great coal beds, and even the extensive de-posits of petroleum found buried in the earth, are the result of bacterial action. It is certainly known that it is only through the action of bacteria that the dead bodies of plants and animals are returned to the soil through the processes of fermentation and putrefaction. Except for this beneficent action of the bacteria the soil would sooner or later become exhausted and the earth would be encumbered with the desiccated forms of plants and animals which had finished their life history. It is thus only through the action of bacteria that the cycle of organic activity is maintained.. Another and notable example of the utility of micro-organisms was brought to light through the remarkable discovery of Tissier, made known to the world by Metchnikoff, that the acid-forming bacteria which are active in fermentation, may be successfully used to combat the poison-forming bacteria that are active in the ...

Significant amounts (| 36??million m3/day) of coalbed methane (CBM) are currently being extracted from coal beds in the Paleocene Fort Union Formation of the Powder River Basin of Wyoming and Montana. Information on processes that generate methane in these coalbed reservoirs is important for developing methods that will stimulate additional production. The chemical and isotopic compositions of gas and ground water from CBM wells throughout the basin reflect generation processes as well as those that affect water/rock interaction. Our study included analyses of water samples collected from 228 CBM wells. Major cations and anions were measured for all samples, ??DH2O and ??18OH2O were measured for 199 of the samples, and ??DCH4 of gas co-produced with water was measured for 100 of the samples. Results show that (1) water from Fort Union Formation coal beds is exclusively Na-HCO3-type water with low dissolved SO4 content (median | 1??mg/L) and little or no...
Download production data for Mexico. Legend: CBM = Coal Bed Methane; UG = Unconventional Gas. Units: billion cubic metres (bcm). Source: Since for most countries no official statistics exist for the various types of unconventional gas, the numbers shown are estimates based on IEA analysis using data from Rystad Energy AS (2015), U.S. Energy Information Administration (2015) and Cedigaz (2014). IEA estimates are also based on National Energy Board (NEB) data from the energy market assessment "Canadas Energy Future 2013 - Energy Supply and Demand Projections to 2035" published by the Government of Canada. These estimates were not produced in affiliation with, or with the endorsement of, the NEB.. Note: The demarcation between conventional and unconventional gas is not always clear cut, especially with respect to tight gas and conventional gas with reservoir stimulation. We classify tight gas as unconventional according to whether we consider that special production techniques, such as hydraulic ...

Bacteriohopanepolyols (BHPs) are bacterial biomarkers with a likely potential to identify present and past methanotrophic communities. To unravel the methanotrophic community in peat bogs, we report the BHP signatures of type I and type II methanotrophs isolated from Sphagnum mosses and of an extreme acidophilic verrucomicrobial methanotroph. A type I Methylovulum-like strain (M200) contains a remarkable combination of BHPs, including a complete suite of mono-unsaturated aminobacteriohopanepentol, -tetrol and -triol. The Methylomonas-like strain (M5) mainly produces aminobacteriohopanepentol, characteristic for type I methanotrophs, and the Methylosinus-like strain (29) contains both aminobacteriohopanetetrol and aminobacteriohopanetriol, typical for a type II methanotroph. The type II methanotroph Methylocella palustris and the verrucomicrobial Methylacidiphilum fumariolicum strain SolV primarily produce aminotriol, which is also produced by many other bacteria. In Sphagnum mosses and ...
DNA mismatch repair (MMR) is a highly conserved biological pathway that plays a key role in maintaining genomic stability. MMR corrects DNA mismatches generated during DNA replication, thereby preventing mutations from becoming permanent in dividing cells. MMR also suppresses homologous recombination and was recently shown to play a role in DNA damage signaling. Defects in MMR are associated with genome-wide instability, predisposition to certain types of cancer including HNPCC, resistance to certain chemotherapeutic agents, and abnormalities in meiosis and sterility in mammalian systems. The Escherichia coli MMR pathway has been extensively studied and is well characterized. In E. coli, the mismatch-activated MutS-MutL-ATP complex licenses MutH to incise the nearest unmethylated GATC sequence. UvrD and an exonuclease generate a gap. This gap is filled by pol III and DNA ligase. The GATC sites are then methylated by Dam. Several human MMR proteins have been identified based on their homology to ...
The Lake Basin fault zone consists mainly of en echelon NE-striking normal faults that have been interpreted to be surface expressions of left-lateral movement along a basement wrench fault. Information gathered from recent field mapping of coal beds and from shallow, closely-spaced drill holes resulted in detailed coal bed correlations, which revealed another linear zone of en echelon faulting directly on the extended trend of the Lake Basin fault zone. This faulted area, referred to as the Sarpy Creek area, is located 48 km E of Hardin, Montana. It is about 16 km long, 13 km wide, and contains 21 en echelon normal faults that have an average strike of N 63oE. We therefore extend the Lake Basin fault zone 32 km farther SE than previously mapped to include the Sarpy Creek area. The Ash Creek oil field, Wyoming, 97 km due S of the Sarpy Creek area, produces from...
The proteasome is a protein-destroying apparatus involved in many essential cellular functions, such as regulation of cell cycle, cell differentiation, signal transduction pathways, antigen processing for appropriate immune responses, stress signaling, inflammatory responses, and apoptosis. It is capable of degrading a variety of cellular proteins in a rapid and timely fashion and most substrate proteins are modified by ubiquitin before their degradation by the proteasome. The proteasome is a large protein complex consisting of a proteolytic core called the 20S particle and ancillary factors that regulate its activity in various ways. The most common form is the 26S proteasome containing one 20S core particle and two 19S regulatory particles that enable the proteasome to degrade ubiquitinated proteins by an ATP-dependent mechanism. Another form is the immunoproteasome containing two 11S regulatory particles, PA28 alpha and PA28 beta, which are induced by interferon gamma under the conditions of ...

Since publication of the first edition of Bergeys Manual of Systematic Bacteriology, it has become recognized throughout the world as the principal monographic work in the field of prokaryotic biology. Like a dictionary to a writer, the Manual is usually the first reference that a microbiologist consults when questions arise regarding the characteristics of an unfamiliar species or an unknown strain that bears some similarity to a more familiar one. While the first edition has served the community well for many years, it has become outdated. As a result, the editorial board of Bergeys Manual Trust, in collaboration with more than 500 of the worlds leading authorities in prokaryotic systematics, is in the process of revising Bergeys Manual of Systematic Bacteriology so that it reflects current thinking and advances in the field. Background Rapid advances in DNA sequencing technology have led to a major change in the way that prokaryotes are classified. Sequence analysis of highly conserved regions

The increasing awareness of the role of phyllosphere microbial communities in plant health calls for a greater understanding of their structure and dynamics in natural ecosystems. Since most knowledge of tree phyllosphere bacterial communities has been gathered in tropical forests, our goal was to characterize the community structure and assembly dynamics of phyllosphere epiphytic bacterial communities in temperate forests in Quebec, Canada. We targeted five dominant tree species: Acer saccharum, Acer rubrum, Betula papyrifera, Abies balsamea, and Picea glauca. We collected 180 samples of phyllosphere communities on these species at four natural forest sites, three times during the growing season. Host functional traits (i.e., wood density, leaf nitrogen content) and climate variables (summer mean temperature and precipitation) were strongly correlated with community structure. We highlight three key findings: (1) temperate tree species share a
