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

One proposed solution to CO2 pollution is to collect the gas and sequester it away from the atmosphere. Nature has already done that for us in the form of vast reserves of coal.
Degasification and methane control in underground coal mining is an important area augmenting conventional ventilation in order to prevent possible fires and explosions due to excessive methane emissions. Coal bed reservoir engineering has been applied for many years to coalbed methane production. In recent years, modeling the flow and draining methane, not only from coal bed itself but also from the overlying strata, have been recognized as important areas of expertise for supplementing underground ventilation. This paper demonstrates the applications of coal bed reservoir engineering and modeling techniques for optimizing and controlling methane emissions in longwall and continuous miner sections. Practical applications and some considerations are presented for reservoir modeling, borehole performances, and face emission predictions for various coal bed and borehole configurations. A section on field reservoir studies and well bore log analyses for methane control are also presented as a ...

Carboniferous rocks in Europe and eastern North America largely consist of a repeated sequence of limestone, sandstone, shale and coal beds.[15] In North America, the early Carboniferous is largely marine limestone, which accounts for the division of the Carboniferous into two periods in North American schemes. The Carboniferous coal beds provided much of the fuel for power generation during the Industrial Revolution and are still of great economic importance. The large coal deposits of the Carboniferous may owe their existence primarily to two factors. The first of these is the appearance of wood tissue and bark-bearing trees. The evolution of the wood fiber lignin and the bark-sealing, waxy substance suberin variously opposed decay organisms so effectively that dead materials accumulated long enough to fossilise on a large scale. The second factor was the lower sea levels that occurred during the Carboniferous as compared to the preceding Devonian period. This promoted the development of ...

Coal bed methane (CBM) production ponds are being constructed more frequently in areas such as the Powder River Basin in Montana and Wyoming where methane production has been active in the past decade. These ponds are currently not being utilized and are holding billions of gallons of water. The extracted water in these ponds is presently being discharged to local stream drainages or infiltrating into the surrounding soil. The environmental impacts of this increase in water can have negative effects on the surrounding areas. The purpose of this thesis is to explore the possibility of using CBM production ponds in the Powder River Basin, in Montana and Wyoming, for the growth of microalgae and the production of biodiesel from their accumulated lipids. Microalgae have been known to grow in other bodies of undesirable water and research has been ongoing on how to effectively use microalgae as a resource by stimulating lipid accumulation through the use of various environmental stressors.

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 ...
BACKGROUND. Hydraulic fracturing (informally known as hydrofracking, fracking, fracing, or hydrofracturing) is a process that typically involves injecting water, sand, and chemicals under high pressure into a bedrock formation via a well. This process is intended to create new fractures in the rock as well as increase the size, extent, and connectivity of existing fractures in order to extract trapped oil and gas.. Hydraulic fracturing is a well-stimulation technique used commonly in low-permeability rocks like tight sandstone, shale, and some coal beds to increase oil and/or gas flow to a well from petroleum-bearing rock formations. A similar technique is used to create improved permeability in underground geothermal reservoirs. A form of hydraulic fracturing is also used in low permeability sediments and other tight subsurface formations to increase the efficiency of soil vapor extraction and other technologies used in remediating contaminated sites.. ...

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...

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 ...
The San Juan Basin of northwest New Mexico and southwest Colorado contains several Upper Cretaceous coal-bearing formations. The coals in these formations were deposited in environments associated with repeated transgressions and regressions of the Western Interior seaway in Late Cretaceous time. A detailed subsurface and surface study of the coal beds in one of these units, the Fruitland Formation, formed the basis for a coal-depositional model (Fassett and Hinds, 1971). This model basically shows that the thickest Fruitland coals formed landward of thickly stacked sandstone beds of the regressive-marine Pictured Cliffs Sandstone. Transferability of the Fruitland coal model was tested by comparing it to another San Juan Basin coal-bearing rock unit, the lower Menefee Formation. Lower Menefee coal deposits were formed in association with the Point Lookout Sandstone, an older regressive-marine unit. The purpose of this comparison was to see if thick lower Menefee coal beds were also concentrated adjacent
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 particulate methane monooxygenase gene clusters, pmoCAB, from two representative type II methanotrophs of the alpha-Proteobacteria, Methylosinus trichosporium OB3b and Methylocystis sp, strain M, have been cloned and sequenced. Primer extension experiments revealed that the pmo cluster is probably transcribed from a single transcriptional start site located 300 bp upstream of the start of the first gene, pmoC, for Methylocystis sp, strain M, Immediately upstream of the putative start site, consensus sequences for sigma(70) promoters were identified, suggesting that these pmo genes are recognized by sigma(70) and negatively regulated under low-copper conditions. The pmo genes were cloned in several overlapping fragments, since parts of these genes appeared to be toxic to the Escherichia coil host. Methanotrophs contain two virtually identical copies of pmo genes, and it was necessary to use Southern blotting and probing with pmo gene fragments in order to differentiate between the two pmoCAB ...
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 ...

A series of experiments were performed using a thermogravimetric analyzer (TGA) to extract the kinetic parameters associated with converting sub-bituminous coal to metallurgical coke. The TGA was close-coupled to an online micro-gas chromatograph in order to continuously measure the vapor products evolved during reaction with a Helium flow of 100 ml min-1. The particle diameter of the coal sample tested ranged from 5mm to 1000mm. Heating rates of 3 and 10 oC min-1 were used to observe the evolution of volatile matter and the production of tar and tar surrogates. Additionally two reactor confinement configurations were tested, a 14.2875 mm wide by 1.5875 mm deep (shallow pan) and a 6.35 mm wide by 1.1125 mm deep (cylindrical crucible), to elucidate the effect of bed depth on vapor product evolution. These configurations provide insight into the relative ratio between condensation, cracking and volatile species reactions. Finally, coal bed density and porosity variations were investigated. The bed ...
