The biogeochemical nitrogen cycle depends on a diverse range of microorganisms that catalyse key reactions such as (i) assimilatory and respiratory (dissimilatory) nitrate and nitrite reduction to ammonium, (ii) denitrification including nitric oxide (NO) production and detoxification as well as nitrous oxide (N2O) respiration, (iii) nitrogen fixation, (iv) nitrification and (v) anaerobic ammonium oxidation (anammox).. An environmentally important intermediate of the nitrogen cycle is nitrous oxide (laughing gas), which is a potent greenhouse gas and an ozone depleting substance. We study the nitrogen metabolism of nitrate/nitrite-ammonifying bacteria that, in addition, are capable to grow by nitrous oxide respiration. A prime example for this type of energy metabolism is the non-pathogenic rumen bacterium Wolinella succinogenes (order Campylobacterales). As this bacterium is known to generate small amounts of nitric oxide (NO) and nitrous oxide during nitrate ammonification, we also explore the ...

Sulfur is an essential element for life and the metabolism of organic sulfur compounds plays an important role in the global sulfur cycle. Sulfur occurs in various oxidation states ranging from +6 in sulfate to -2 in sulfide (H2S). Sulfate reduction can occur in both an energy consuming assimilatory pathway and an energy producing dissimilatory pathway. The assimilatory pathway, which is found in a wide range of organisms, produces reduced sulfur compounds for the biosynthesis of S-containing amino acids and does not lead to direct excretion of sulfide. In the dissimilatory pathway, which is restricted to obligatory anaerobic bacterial and archaeal lineages, sulfate (or sulfur) is the terminal electron acceptor of the respiratory chain producing large quantities of inorganic sulfide. Both pathways start from the activation of sulfate by reaction with ATP to form adenylyl sulfate (APS). In the assimilatory pathway [MD:M00176] APS is converted to 3-phosphoadenylyl sulfate (PAPS) and then reduced ...

Butyrivibrio fibrisolvens ced1 protein: shows cellodextrinase activity & rapidly hydrolyzes short-chain cellodextrins to yield either cellobiose or cellobiose & glucose as end products; releases cellobiose from p-nitrophenyl-beta-D-cellobioside & is not inhibited by methyl cellulose; amino acid sequence given in first source; from Butyrivibrio fibrisolvens H17c

The Butyrivibrio fibrisolvens/Escherichia coli shuttle vector pBHerm has been modified to produce a plasmid (pBHE) that can be used for the identification and characterization of promoters in B. fibrisolvens. pBHE allows the insertion of a test promoter immediately upstream of a promoterless erythromycin resistance gene (ermAM). The efficacy of the pBHE plasmid in isolating and characterizing promoters was tested by inserting the flagellin gene (flaA) promoter from B. fibrisolvens OR77. Transcription of the ermAM gene from the flaA promoter was significantly higher than that observed when the ermAM gene was under the control of its own promoter. The flagelling gene of OR77 appears to be transcribed from two different promoters that produce transcripts initiating approximately 130 bp apart. Two mutant flaA promoter constructs, containing mutations in the −10 and −35 regions of either of the two putative promoter regions, showed drastic alterations in both the origin and amounts of the two ...

Bacteroides coprosuis Whitehead et al. 2005 belongs to the genus Bacteroides, which is a member of the family Bacteroidaceae. Members of the genus Bacteroides in general are known as beneficial protectors of animal guts against pathogenic microorganisms, and as contributors to the degradation of complex molecules such as polysaccharides. B. coprosuis itself was isolated from a manure storage pit of a swine facility, but has not yet been found in an animal host. The species is of interest solely because of its isolated phylogenetic location. The genome of B. coprosuis is already the 5th sequenced type strain genome from the genus Bacteroides. The 2,991,798 bp long genome with its 2,461 protein-coding and 78 RNA genes and is a part of the Genomic Encyclopedia of Bacteria and Archaea project.

Bacteroides barnesiae Lan et al. 2006 is a species of the genus Bacteroides, which belongs to the family Bacteroidaceae. Strain BL2T is of interest because it was isolated from the gut of a chicken and the growing awareness that the anaerobic microbiota of the caecum is of benefit for the host and may impact poultry farming. The 3,621,509 bp long genome with its 3,059 protein-coding and 97 RNA genes is a part of the Genomic Encyclopedia of Type Strains, Phase I: the one thousand microbial genomes (KMG) project.

A new genus of cellulolytic, gram-negative, nonsporeforming, anaerobic bacteria is described. The colonies produced by these bacteria on cellulose agar were round, clear, translucent, and cream-colored and had an undulate margin. Single cells of the bacterium were straight to slightly curved rods 0.5 to 0.8 μm wide by 4 to 10 μm long and were motile by means of a single flagellum located one-third of the distance from the end of the cell. Among the various substrates tested, only cellulose, cellobiose, and salicin were able to support growth. The major fermentation products of cellobiose or cellulose degradation were acetic acid, hydrogen, and carbon dioxide. The deoxyribonucleic acid base composition of the type species was 38 mol% guanine plus cytosine. The name Acetivibrio is proposed for this new genus, which is placed in the family Bacteroidaceae. The type species, Acetivibrio cellulolyticus sp. nov., is named on the basis of its cellulolytic activity. The type strain of A. cellulolyticus is CD2

The imbalance of gut microbiota is known to be associated with inflammatory bowel disease, but it remains unknown whether dysbiosis is a cause or consequence of chronic gut inflammation. In order to investigate the effects of gut inflammation on microbiota and metabolome, the sequential changes in gut microbiota and metabolites from the onset of colitis to the recovery in dextran sulfate sodium-induced colitic mice were characterized by using meta 16S rRNA sequencing and proton nuclear magnetic resonance (1H-NMR) analysis. Mice in the colitis progression phase showed the transient expansions of two bacterial families including Bacteroidaceae and Enterobacteriaceae and the depletion of major gut commensal bacteria belonging to the uncultured Bacteroidales family S24-7, Rikenellaceae, Lachnospiraceae, and Ruminococcaceae. After the initiation of the recovery, commensal Lactobacillus members promptly predominated in gut while other normally abundant bacteria excluding the Erysipelotrichaceae remained

A notable feature of this and other clone library analyses from G.I. environments is the number of sequences that do not cluster with any known species. Sequences from nonruminant feces fell within the genera Bacteroides and Prevotella, while most sequences from ruminant hosts did not cluster with any known species. Both the range of sequence identity with the closest known species (87 to 91%) and the interclade identity range (81 to 94%) suggest that taxonomic diversity exists among ruminant sequences. Representatives of these groups must be isolated before phenotypic characterization or classification can be determined.. Within the genus Bacteroides, cloned sequences were closely related to known species, reflecting the greater number of cultivated representatives in this genus. This in turn reflects a greater emphasis placed on the study of the human fecal flora relative to other animal hosts. Many cultivated Bacteroides species, particularly B. vulgatus, B. uniformis, B. thetaiotaomicron, ...

Degradation of the mechanical integrity of cobalt-based superalloys can occur as the carbide network is progressively oxidised during high temperature service. In this study, a heat-treatment aimed at redistributing the carbides was tested on two similar commercial Co-based superalloys, one with high C content (Co-101) and one with low C content (Stellite-21), to determine its influence on oxidation resistance. It was found that the carbide phases in the lower C-containing alloy could be solutioned more readily than the higher C-containing alloy, enabling the continuity of the carbide network to be reduced. This resulted in a reduced attack of the carbides down the interdendritic channels during oxidation testing, but increased thickness of the oxide overscale ...

SUMMARY: An antigenic determinant isolated from a strain of the Gram-negative bacterium Butyrivibrio fibrisolvens reacted with specific antisera to the polyglycero-phosphate backbone of membrane teichoic acids of lactobacilli. It gave a reaction of identity with membrane glycerol lipoteichoic acid and glycerol teichoic acid preparations from lactobacilli, and with phenol extracts of other Gram-positive bacteria. The antigen-antibody reaction was strongly inhibited by glycerol-phosphoryl-glycerol-phosphoryl-glycerol and the chemical composition was consistent with glycerol teichoic acid. It was concluded that this Gram-negative bacterium contained a glycerol teichoic acid whose polyglycerophosphate backbone was acting as antigenic determinant. Extracts of 33 out of 52 other strains of butyrivibrios examined gave similar reactions.
