Cellobiose versus glucose utilization by the ruminal bacterium Ruminococcus albus. Isolation and characterization of Selenomonas ruminantium strains capable of 2-deoxyribose utilization
To determine how the increased oxidative stress of the IBD gut shapes the composition of the gut microbiome, we first needed to bin the species of the gut microbiome by their ability to respond to oxidative stress (rather than by their taxonomic classification). Based on literature review (Methods), we manually binned species into two categories: i) oxygen-utilizing organisms (also known as facultative anaerobes, which can grow with or without oxygen); and ii) organisms that cannot use oxygen as a terminal electron acceptor (namely, aerotolerant and obligate anaerobes, which are both unable to grow in oxygen; however, unlike obligate anaerobes, aerotolerant bacteria are not rapidly poisoned by atmospheric oxygen) (Additional file 2: Table S2).. We found a consistent signal of increased facultative anaerobe abundance in IBD patients across both the LSS and the Lewis et al. cohorts (p value = 0.0478 and 0.005, respectively; Fig. 1b). IBD patients from the LSS and Lewis et al. cohorts showed mean ...
Background Ruminococcus flavefaciens is a predominant cellulolytic rumen bacterium, which forms a multi-enzyme cellulosome complex that could play an integral role in the ability of this bacterium to degrade plant cell wall polysaccharides. Identifying the major enzyme types involved in plant cell wall degradation is essential for gaining a better understanding of the cellulolytic capabilities of this organism as well as highlighting potential enzymes for application in improvement of livestock nutrition and for conversion of cellulosic biomass to liquid fuels. Methodology/Principal Findings The R. flavefaciens FD-1 genome was sequenced to 29x-coverage, based on pulsed-field gel electrophoresis estimates (4.4 Mb), and assembled into 119 contigs providing 4,576,399 bp of unique sequence. As much as 87.1% of the genome encodes ORFs, tRNA, rRNAs, or repeats. The GC content was calculated at 45%. A total of 4,339 ORFs was detected with an average gene length of 918 bp. The cellulosome model for R.
Abstract: Sialic acid (N-acetylneuraminic acid (Neu5Ac)) is commonly found in the terminal location of colonic mucin glycans where it is a much-coveted nutrient for gut bacteria, including Ruminococcus gnavus. R. gnavus is part of the healthy gut microbiota in humans, but it is disproportionately represented in diseases. There is therefore a need to understand the molecular mechanisms that underpin the adaptation of R. gnavus to the gut. Previous in vitro research has demonstrated that the mucin-glycan-foraging strategy of R. gnavus is strain dependent and is associated with the expression of an intramolecular trans-sialidase, which releases 2,7-anhydro-Neu5Ac, rather than Neu5Ac, from mucins. Here, we unravelled the metabolism pathway of 2,7-anhydro-Neu5Ac in R. gnavus that is underpinned by the exquisite specificity of the sialic transporter for 2,7-anhydro-Neu5Ac and by the action of an oxidoreductase that converts 2,7-anhydro-Neu5Ac into Neu5Ac, which then becomes a substrate of a ...
A monoclonal antibody (MAb S1) generated against Exoglucanase A was used to investigate cellulolysis by R. flavefaciens. MAb S1 recognized few components in crude cellulase demonstrating its specificity for Exoglucanase A. MAb S1 was used to investigate the cellular location of the Exoglucanase A. Thin-sectioning of R. flavefaciens followed by immunolabelling, and examination using a transmission electron microscope showed a non-specific interaction of the monoclonal antibody for the embedding resin. Although, various treatments were tried to prevent this interaction, no conclusions about the cellular location of Exoglucanase A could be drawn. MAb S1 also inhibited the action of Exoglucanase A in vitro but failed to inhibit growth of R. flavefaciens when added to culture medium. This suggests the action of Exoglucanase A is not necessary for growth or the antibody concentration in the medium was too low to affect growth ...
Background: Faecalibacterium prausnitzii comprises 2 phylogroups, whose abundance in healthy and diseased gut and in conjunction with Escherichia coli has not yet been studied. This work aims to determine the contribution of F. prausnitzii phylogroups I and II in intestinal disease and to assess their potential diagnostic usefulness as biomarkers for gut diseases. Methods: Total F. prausnitzii, its phylogroups, and E. coli loads were determined by quantitative polymerase chain reaction targeting the 16S rRNA gene on biopsies from 31 healthy controls (H), 45 patients with Crohns disease (CD), 25 patients with ulcerative colitis, 10 patients with irritable bowel syndrome, and 20 patients with colorectal cancer. Data were normalized to total bacterial counts and analyzed according to patients disease location and clinical characteristics. Results: Lower levels of both total F. prausnitzii and phylogroup I were found in subjects with CD, ulcerative colitis, and colorectal cancer (P , 0.001) ...

A vast majority of intestinal bacteria belong to one of two phylum of bacteria: Firmicutes and Bacteroidetes. Among these two phylum the bacteria in the intestinal with the largest populations are thought to be (in no particular order) genera Bacteroides (bact.), Clostridium (firm.), Bifidobacterium (bact.), Peptostreptococcus (firm.) and Ruminococcus (firm.) with minor populations of Escherichia (proteo), Lactobacillus (firm), Enterobacter (proteo) and Enterococcus (firm) with various methanogens.3,8,9. The parentheses identify the phylum type for the particular bacteria. It must be emphasized that specifics regarding exact populations are still far and few between relative to the specific genus which make up the Firmicutes and Bacteroidetes phylums for they contain 250 and 20 genera respectively;10 however, it is thought that Ruminococcus makes up a significant percentage of the Firmicutes phylum. On a side note Firmicutes bacteria are typically gram-positive (outside a very small few which ...
5.3.1 Aquatic bioaccumulation- SCAE Me category No experimental data evaluating the bioaccumulation potential of the SCAE Me category members are available. All substances within the SCAE Me category have log Kow values above 3, suggesting potential to bioaccumulate in biota, with the exception of methyl hexanoate (CAS No. 106-70-7). The log Kow value estimated for this substance is 2.3 and therefore, according to Regulation (EC) No. 1907/2006, Annex IX, Column 2, 9.3.2, this substance can be considered to have low bioaccumulation potential (log Kow ≤ 3). Regarding the rest of the SCAE Me category members, the information gathered on environmental behaviour and metabolism in combination with the QSAR-estimated BCF values provide enough evidence (in accordance to the REACh Regulation (EC) No 1907/2006, Annex XI General rules for adaptation of the standard testing regime set out in Annexes VII to X, 1.2, to cover the data requirements of Regulation (EC) No. 1907/2006, Annex IX) to state that ...

Effects of supplementation with ruminal epithelial cells on fiber-degrading activity and cell growth of Ruminococcus albus (R. albus, strain 7) was tested using a basal substrate of rice straw and formulated concentrate. Cultures of R. albus alone and R. albus with rumen protozoa were grown at 39째C for 48 h with an 8.4% crude protein (CP) substrate, 33% of the CP supplemented with either ruminal epithelial cells or defatted soybean meal. The ruminal epithelial cells had lower amounts of rumen soluble and degradable protein fractions as compared to defatted soybean meal, as determined by an enzymatic method, and the same was found with amino acid composition of protein hydrolysates. Ruminal epithelial cells were directly utilized by the R. albus, and resulted in greater growth of cell-wall free bacteria compared to defatted soybean meal. The effect of epithelial cells on bacterial growth was enhanced by the presence of rumen protozoa. In consistency with cultures of R. albus and R. albus with ...
In this study we hypothesised that dysbiosis is important not only in CD but also in UC pathophysiology and that this dysbiosis may partly overlap with the dysbiosis observed in CD. We therefore evaluated if the predominant microbial signature as we previously described in CD is also present in UC.24 The CD-associated signature was characterised by five bacterial species, namely a decrease in F prausnitzii, B adolescentis, D invisus and an uncharacterised species of Clostridium cluster XIVa, and an increase in R gnavus. In contrast, when we evaluated the culturable species F prausnitzii, B adolescentis and R gnavus in the present UC cohort, we did not find the same signature in UC patients based on DGGE analysis. Our study has shortcomings including the mixed patient population, a potential impact of differences in duration of therapy on the microbiota and the lack of information on dietary aspects. It might be possible that disease-relevant species could be missed using DGGE instead of ...
Faecalibacterium prausnitzii is an anti-inflammatory commensal bacterium identified on the basis of human clinical data. The mechanisms underlying its beneficial effects are still unknown. Gnotobiotic mice harboring F. prausnitzii (A2-165) and Escherichia coli (K-12 JM105) were subjected to 2,4,6-trinitrobenzenesulfonic acid (TNBS)-induced acute colitis. The inflammatory colitis scores and a gas chromatography-time of flight (GC/TOF) mass spectrometry-based metabolomic profile were monitored in blood, ileum, cecum, colon, and feces in gnotobiotic mice. The potential anti-inflammatory metabolites were tested in vitro. We obtained stable E. coli and F. prausnitzii-diassociated mice in which E. coli primed the gastrointestinal tract (GIT), allowing a durable and stable establishment of F. prausnitzii. The disease activity index, histological scores, myeloperoxidase (MPO) activity, and serum cytokine levels were significantly lower in the presence of F. prausnitzii after TNBS challenge. The ...

A set of seven new oligonucleotide probes is presented to extend the set of probes for the predominant microbiota of the human gastrointestinal tract and in particular for fecal bacteria. Five of the seven probes each detected an average of more than 1% of the total bacterial microbiota. Especially the probes for the ruminococci and related Clostridium group IV bacteria are valuable, since these probes detected 10% of the fecal bacteria, and this group of bacteria is likely to have interesting metabolic features, such as degradation of complex carbohydrates. The numbers of the ruminococcus group are within the range earlier estimated in human feces by culture techniques (7), in which a mean of 1.6 × 1010 g−1 (dry weight) was found. Also the numbers of the Eubacterium cylindroides group are within the reported ranges. The numbers of C. innocuum, E. cylindroides, and Eubacterium dolichum enumerated previously showed a large variation between the subjects with mean numbers of 4 × 108, 4 × 109, ...

It has been suggested that increased risk for chronic inflammatory diseases associated with C-section is a result of the long-term dysbiosis observed in children delivered by C-section (reviewed in Ref. 39). In this study, we demonstrated in a murine model that mode of delivery had a major impact on the early composition of the gut microbiota in mice, as analysis by 16S rRNA gene sequencing confirmed a separate clustering of the vaginally delivered and C-section pups. A distinct bacterial profile enriched in especially Bacteroides and Lachnospiraceae and with lower abundance of Rikenellaceae and Ruminococcus was characteristic for the C-section pups. On the contrary, C-section has been shown to cause decreased colonization rate of Bacteroides and increased prevalence of Clostridia in humans (40). These differences may, besides genetic differences, be because of the initial colonization pattern being very susceptible to environmental changes. When human babies are not exposed to maternal vaginal ...

DNA from the batch culture fluid and rumen contents in the feeding study was extracted and purified using the repeated bead beating plus column method [19] with a DNA stool mini kit (QIAamp DNA Stool Mini Kit; Qiagen, Hilden, Germany). The purified DNA was quantified using a NanoDrop 2000 (Thermo Fisher Scientific, Waltham, MA, USA) and diluted to 10 ng/μL before being subjected to polymerase chain reaction (PCR) amplification. The diluted DNA was used for quantitative real-time PCR (qPCR) to monitor the abundance of rumen representatives including total bacteria, total archaea, fungi, protozoa, Fibrobacter succinogenes (F. succinogenes), Ruminococcus albus (R. albus), Ruminococcus flavefaciens (R. flavefaciens), genus Prevotella, Prevotella bryantii, Prevotella ruminicola (P. ruminicola), Anaerovibrio lipolytica (A. lipolytica), and Butyrivibrio group. Details of qPCR such as primers, standards, PCR conditions, and calculations were as described by Koike et al [20] and Ohene-Adjei et al [21]. ...
The nucleotide positions of the target site for the forward primer on T. bryantii 16S rRNA gene sequences were 380-400 while those of the reverse primer were 934-953, yielding a 575-bp PCR product. The primer set was designed to cover all rumen Treponema and named g-TrepoF. The online basic local alignment search tool (blast) program (http://blast.ncbi.nlm.nih.gov/Blast.cgi) was used to determine the specificity of the forward primer.. The specificity of the primers was further tested by PCR amplification using genomic DNA from pure cultures of 16 representative rumen bacterial strains including T. bryantii ATCC33254, F. succinogenes ATCC19169, Ruminococcus albus 8, Ruminococcus flavefaciens C94, Prevotella ruminicola 23, Prevotella bryantii B14, Prevotella brevis GA33, Butyrivibrio fibrisolvens.

The physiological responses of unfed and postprandial red rock crabs (Cancer productus J.W. Randal, 1840) were investigated during periods of emersion. During aerial exposure, oxygen uptake quickly fell to very low levels and was no longer detectable in the haemolymph after 12 h. The resulting anaerobic respiration led to a build up in lactic acid and the resulting acidosis was more pronounced in the postprandial crabs. There was also a concomitant rise in PCO2 and CCO2, and in both cases these were higher in postprandial animals. Higher ammonia levels in postprandial crabs showed that cellular activities were still proceeding anaerobically, suggesting that although crabs can delay mechanical digestion during emersion, once intracellular digestion occurs they may be committed to these processes. Increased mortality rates of postprandial animals were probably due to a combination of the high lactate and CO2 levels coupled with an increased ammonia concentration. For C. productus stranded in the ...
Objective Bacteria play an important role in the onset and perpetuation of intestinal inflammation in inflammatory bowel disease (IBD). Unlike in Crohns disease (CD), in which dysbiosis has been better characterised, in ulcerative colitis (UC), only small cohorts have been studied and showed conflicting data. Therefore, we evaluated in a large cohort if the microbial signature described in CD is also present in UC, and if we could characterise predominant dysbiosis in UC. To assess the functional impact of dysbiosis, we quantified the bacterial metabolites.. ...

A few weeks ago (June 2012), a paper in Nature by a group of researchers suggested that despite the vast geographical and nutritional differences in the human population, that just three predominant bacterial clusters (referred to as enterotypes hereafter) could explain all of our gastric microbial mixes.[1] This they suggest indicates the existence of a limited number of well-balanced host-microbial symbiotic states that might respond differently to diet and drug intake.. Each of these three enterotypes are identifiable by the variation in the levels of one of three genera: Bacteroides (enterotype 1), Prevotella (enterotype 2) and Ruminococcus (enterotype 3). These enterotypes are not as sharply delimited as, for example, human blood groups; they are, in contrast, densely populated areas in a multidimensional space of community composition. They are nevertheless likely to characterise individuals, in line with previous reports that gut microbiota are quite stable in individuals and can even be ...

consuming timothy hay and a commercial concentrate (60:40, w/w) twice daily (09:00 and 17:00) at 2% of body weight with free access to water and mineral block were used as rumen fluid donors. In vitro fermentation experiment, with timothy hay as substrate, was conducted for up to 72 h, with E. stolonifera extract added to achieve final concentration 1%, 3%, and 5% on timothy hay basis. Results: Administration of E. stolonifera extract to a ruminant fluid-artificial saliva mixture in vitro increased the total gas production. Unexpectedly, E. stolonifera extracts appeared to increase both methane emissions and hydrogen production, which is contrasts with previous observations with brown algae extracts used under in vitro fermentation conditions. Interestingly, real-time polymerase chain reaction indicated that as compared with the untreated control the ciliate-associated methanogen and Fibrobacter succinogenes populations decreased, whereas the Ruminococcus flavefaciens population increased as a ...
The authors state in the results: Ten human subjects consumed crackers for three weeks each containing either RS2, RS4, or native starch in a double-blind, crossover design. Multiplex sequencing of 16S rRNA tags revealed that both types of RS induced several significant compositional alterations in the fecal microbial populations, with differential effects on community structure. RS4 but not RS2 induced phylum-level changes, significantly increasing Actinobacteria and Bacteroidetes (+++)while decreasing Firmicutes(-). At the species level, the changes evoked by RS4 were increases in Bifidobacterium adolescentis and Parabacteroides distasonis, while RS2 significantly raised the proportions of Ruminococcus bromii and Eubacterium rectale when compared to RS4. The population shifts caused by RS4 were numerically substantial for several taxa, leading for example, to a ten-fold increase in bifidobacteria in three of the subjects, enriching them to 18-30% of the fecal microbial community. The ...
Coprococcus (ATCC 27759) is a genus of anaerobic cocci which are all part of the human faecal flora, but rarely seen in human clinical specimens. Coprococcus includes those gram-positive, anaerobic cocci that actively ferment carbohydrates, producing butyric and acetic acids with formic or propionic and/or lactic acids. Fermentable carbohydrates are either required or are highly stimulatory for growth and continued subculture. - Lillian V. Holdeman & W. E. C. Moore. The genus is bio-chemically closely related to Ruminococcus, and phylogenetically to the genus Lachnospira. Coprococcus eutactus is an obligately anaerobic, nonmotile, gram-positive coccus occurring in pairs or chains of pairs. Cells may lose colour readily and acquire a slightly elongate shape in a medium containing a fermentable carbohydrate, but are normally round, and 0.7 to 1.3 µm in diameter. Coprococcus may be used as a microbial biomarker to assess the health of the human gastro-intestinal tract. Gut microorganisms ...
