Clostridium glycolicum ATCC ® 14880D™ Designation: Genomic DNA from Clostridium glycolicum TypeStrain=True Application:
Clostridium novyi (oedematiens) a Gram-positive, endospore- forming, obligate anaerobic bacteria of the class clostridia. It is ubiquitous, being found in the soil and faeces. It is pathogenic, causing a wide variety of diseases in man and animals. It comes in three types, labelled A, B, and a non-pathogenic type C distinguished by the range of toxins they produce. Some authors include Clostridium haemolyticum as Clostridium novyi type D. C novyi is closely related to Clostridium botulinum types C and D as Yoshimasa Sasaki et al. have demonstrated by 16S rDNA sequence analysis. Growth in culture proceeds through 3 stages: Initial growth wherein no toxin is produced; vigorous growth wherein toxin is produced; and spore formation wherein endospores are formed and toxin production decreases. It is suggested that type C may be type B that forms spores more readily so does not go through the toxin-production stage. Isolating and identifying C novyi is difficult due to its extreme anaerobic nature. ...
Clostridium innocuum (CLOIN) is an anaerobic, non-motile, gram-positive bacterium that reproduces by sporulation. While there are over 130 species of Clostridia, C. innocuum is the third most commonly isolated. Although it is not normally considered an aggressive human pathogen, it has been isolated in some disease processes. C. innocuum and other Clostrida line the oropharynx and gastrointestinal tract, and are considered normal gut flora. Anaerobic gram-positive bacilli affecting human beings are generally divided into two distinct groups, those that form spores (Clostridium spp) and those that do not form spores. Within the spore-forming group of Clostridium species, some are very pathogenic or toxigenic (C. perfringens) while others are rarely pathogenic. Identification and differentiation between anaerobic gram-positive bacteria in a clinical laboratory can be a very difficult task. C. innocuum forms white, glossy, raised colonies and exhibits a chartreuse fluorescence. It is a small, ...

Abstract: A group-specific PCR-based denaturing gradient gel electrophoresis (DGGE) method was developed and combined with group-specific clone library analysis to investigate the diversity of the Clostridium leptum subgroup in human feces. PCR products (length, 239 bp) were amplified using C. leptum cluster-specific primers and were well separated by DGGE. The DGGE patterns of fecal amplicons from 11 human individuals revealed host-specific profiles; the patterns for fecal samples collected from a child for 3 years demonstrated the structural succession of the population in the first 2 years and its stability in the third year. A clone library was constructed with 100 clones consisting of 1,143-bp inserts of 16S rRNA gene fragments that were amplified from one adult fecal DNA with one forward universal bacterial primer and one reverse group-specific primer. Eighty-six of the clones produced the 239-bp C. leptum cluster-specific amplicons, and the remaining 14 clones did not produce these ...

Butanol is currently one of the most discussed biofuels. Its use provides many benefits in comparison to bio-ethanol, but the price of its fermentative production is still high. Genetic improvements could help solve many problems associated with butanol production during ABE fermentation, such as its toxicity, low concentration achievable in the cultivation medium, the need for a relatively expensive substrate, and many more. Clostridium pasteurianum NRRL B-598 is non-type strain producing butanol, acetone, and a negligible amount of ethanol. Its main benefits are high oxygen tolerance, utilization of a wide range of carbon and nitrogen sources, and the availability of its whole genome sequence. However, there is no established method for the transfer of foreign DNA into this strain; this is the next step necessary for progress in its use for butanol production. We have described functional protocols for conjugation and transformation of the bio-butanol producer C. pasteurianum NRRL B-598 by foreign
The transport of 99MoO42- into dinitrogen-fixing cells of Clostridium pasteurianum was investigated. Transport of molybdate in this organism is energy dependent; sucrose is required in the minimal media, and the system is inhibited by the glycolysis inhibitors, NaF, iodoacetic acid, and arsenate. The cells accumulate molybdate against a concentration gradient, and the uptake shows a marked dependence on temperature (optimum 37 C) and pH (optimum 6.0). The rate of molybdate uptake with increasing molybdate concentrations shows saturation kinetics with an apparent Km and Vmax of 4.8 X 10(-5) M and 55 nmol/g of dry cells per min, respectively. Inhibition studies with the anions SO42-, S2O32-, WO42-, and VO32- show that SO42- and WO42- competitively inhibit MoO42- uptake (apparent Ki [SO42-] is 3.0 X 10(-5) M; apparent Ki [WO42-] is 2.4 X 10(-5), whereas S2O32- and VO32- have no inhibitory effect. Exchange experiments with MoO42- show that only a small percentage of the 99MoO42- taken up by the ...
Conference Comment: The contributor provides a good summary of C. piliforme, an atypical member of the genus Clostridium. Other members of the clostridia are large, Gram positive spore forming bacteria with straight or slightly curved morphology, in contrast the filamentous, Gram negative spore forming C. piliforme.(2) Further differentiating C. piliforme from other clostridia is the fact that it does not possess characteristics that allow its inclusion into one of the three general categories of the other pathogenic members of the genus. These categories of clostridia are neurotoxic (C. tetani, C. botulinum types A-G), histotoxic (C. chauvoei, C. septicum, C. novyi types A and B, C. perfringens type A, C. sordellii, C. hemolyticum), and enteropathogenic/enterotoxemia-producing (C. perfringens types A-E, C. difficile, C. colinum, C. spiroforme).(2 ...
Some pathogenic spore-forming bacilli employ a binary protein mechanism for intoxicating the intestinal tracts of insects, animals, and humans. These Gram-positive bacteria and their toxins include Clostridium botulinum (C2 toxin), Clostridium difficile (C. difficile toxin or CDT), Clostridium perfringens (ι-toxin and binary enterotoxin, or BEC), Clostridium spiroforme (C. spiroforme toxin or CST), as well as Bacillus cereus (vegetative insecticidal protein or VIP). These gut-acting proteins form an AB complex composed of ADP-ribosyl transferase (A) and cell-binding (B) components that intoxicate cells via receptor-mediated endocytosis and endosomal trafficking. Once inside the cytosol, the A components inhibit normal cell functions by mono-ADP-ribosylation of globular actin, which induces cytoskeletal disarray and death. Important aspects of each bacterium and binary enterotoxin will be highlighted in this review, with particular focus upon the disease process involving the biochemistry and modes of

Clostridium pasteurianum is emerging as a prospective host for the production of biofuels and chemicals, and has recently been shown to directly consume electric current. Despite this growing biotechnological appeal, the organisms genetics and central metabolism remain poorly understood. Here we present a concurrent genome sequence for the C. pasteurianum type strain and provide extensive genomic analysis of the organisms defence mechanisms and central fermentative metabolism. Next generation genome sequencing produced reads corresponding to spontaneous excision of a novel phage, designated φ6013, which could be induced using mitomycin C and detected using PCR and transmission electron microscopy. Methylome analysis of sequencing reads provided a near-complete glimpse into the organisms restriction-modification systems. We also unveiled the chief C. pasteurianum Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) locus, which was found to exemplify a Type I-B system. Finally, we show

General Information: Solvent-producing bacterium. This genus comprises about 150 metabolically diverse species of anaerobes that are ubiquitous in virtually all anoxic habitats where organic compounds are present, including soils, aquatic sediments and the intestinal tracts of animals and humans. This shape is attributed to the presence of endospores that develop under conditions unfavorable for vegetative growth and distend single cells terminally or sub-terminally. Spores germinate under conditions favorable for vegetative growth, such as anaerobiosis and presence of organic substrates. It is believed that present day Mollicutes (Eubacteria) have evolved regressively (i.e., by genome reduction) from gram-positive clostridia-like ancestors with a low GC content in DNA. Some species are capable of producing organic solvents (acetone, ethanol, etc,), molecular hydrogen and other useful compounds. There are also species that can fix molecular nitrogen and thus are important participants in ...

The increase in glycerol obtained as a byproduct of biodiesel has encouraged the production of new industrial products, such as 1,3-propanediol (PDO), using biotechnological transformation via bacteria like Clostridium butyricum. However, despite the increasing role of Clostridium butyricum as a bio-production platform, its metabolism remains poorly modeled. We reconstructed iCbu641, the first genome-scale metabolic (GSM) model of a PDO producer Clostridium strain, which included 641 genes, 365 enzymes, 891 reactions, and 701 metabolites. We found an enzyme expression prediction of nearly 84% after comparison of proteomic data with flux distribution estimation using flux balance analysis (FBA). The remaining 16% corresponded to enzymes directionally coupled to growth, according to flux coupling findings (FCF). The fermentation data validation also revealed different phenotype states that depended on culture media conditions; for example, Clostridium maximizes its biomass yield per enzyme usage under
One of the biggest limitations in the study and engineering of anaerobic Clostridium organisms is the lack of strong fluorescent reporters capable of strong and real-time fluorescence. Recently, we developed a strong fluorescent reporter system for Clostridium organisms based on the FAST protein. Here, we report the development of two new strong fluorescent reporter systems for Clostridium organisms based on the HaloTag and SNAP-tag proteins, which produce strong fluorescent signals when covalently bound to fluorogenic ligands. These new fluorescent reporters are orthogonal to the FAST ligands and to each other, allowing for simultaneous labeling and visualization. We used HaloTag and SNAP-tag to label the strictly anaerobic organisms Clostridium acetobutylicum and Clostridium ljungdahlii. We have also identified a new strong promoter for protein expression in C. acetobutylicum, based on the phosphotransacetylase gene (pta) from C. ljungdahlii. Furthermore, the HaloTag and the SNAP-tag, in ...
Ruminiclostridium cellulolyticum and Lachnoclostridium phytofermentans (formerly known as Clostridium cellulolyticum and Clostridium phytofermentans, respectively) are anaerobic bacteria that developed different strategies to depolymerize the cellulose and the related plant cell wall polysaccharides. Thus, R. cellulolyticum produces large extracellular multi-enzyme complexes termed cellulosomes, while L. phytofermentans secretes in the environment some cellulose-degrading enzymes as free enzymes. In the present study, the major cellulase from L. phytofermentans was introduced as a free enzyme or as a cellulosomal component in R. cellulolyticum to improve its cellulolytic capacities. The gene at locus Cphy_3367 encoding the major cellulase Cel9A from L. phytofermentans and an engineered gene coding for a modified enzyme harboring a R. cellulolyticum C-terminal dockerin were cloned in an expression vector. After electrotransformation of R. cellulolyticum, both forms of Cel9A
The nucleotide sequence of the celY gene coding for the thermostable exo-1,4-β-glucanase Avicelase II of Clostridium stercorarium was determined. The gene consists of an ORF of 2742 bp which encodes a preprotein of 914 amino acids with a molecular mass of 103 kDa. The signal-peptide cleavage site was identified by comparison with the N-terminal amino acid sequence of Avicelase II purified from C. stercorarium. The celY gene is located in close vicinity to the celZ gene coding for the endo-1,4-β-glucanase Avicelase I. The CelY-encoding sequence was isolated from genomic DNA of C. stercorarium with the PCR technique. The recombinant enzyme produced in Escherichia coli as a LacZ'-CelY fusion protein could be purified using a simple two-step procedure. The properties of CelY proved to be consistent with those of Avicelase II purified from C. stercorarium. Sequence comparison revealed that CelY consists of an N-terminal catalytic domain flanked by a domain of 95 amino acids with unknown function
Increasing demand for the production of renewable fuels has recently generated a particular interest in microbial production of butanol. Anaerobic bacteria, such as Clostridium spp., can naturally convert carbohydrates into a variety of primary products, including alcohols like butanol. The genetics of microorganisms like Clostridium acetobutylicum have been well studied and their solvent-producing metabolic pathways characterized. In contrast, less is known about the genetics of Clostridium spp. capable of converting syngas or its individual components into solvents. In this study, the type of strain of a new solventogenic Clostridium species, C. carboxidivorans, was genetically characterized by genome sequencing. C. carboxidivorans strain P7T possessed a complete Wood-Ljungdahl pathway gene cluster, involving CO and CO2 fixation and conversion to acetyl-CoA. Moreover, with the exception of an acetone production pathway, all the genetic determinants of canonical ABE metabolic pathways for acetate,
SUMMARY: Evidence is provided in support of the view of MacLennan, Mandl & Howes (1958) that some strains of Clostridium histolyticum produce a cysteine-inactivated proteinase-the δ-antigen.
Background:Clostridium tertium is distributed in the soil and in animal and human gastrointestinal tracts. C. tertium has been isolated from patients with blood diseases, immune disorders, and abdominal surgeries. Glyphosate is toxic, causing cause eye and skin irritation, gastrointestinal pain, and vomiting. Ingestion of herbicides modifies the gastrointestinal environment, which stresses the living organisms. However, there has been little attention to cases of bacteremia in patients recovering from suicide attempt by ingesting herbicide. Case Report:Clostridium tertium was identified in a 44-year-old female who attempted suicide by glyphosate (a herbicide) ingestion. The 16S rRNA sequences from all colonies were 99% identical with that of C. tertium (AB618789) found on a BLAST search of the NCBI database. The bacterium was cultured on TSA under aerobic and anaerobic conditions. Antimicrobial susceptibility tests performed under both aerobic and anaerobic conditions showed that the bacterium was

Lethal Toxin from Clostridium sordellii (TcsL), which is casually involved in the toxic shock syndrome and in gas gangrene, enters its target cells by receptor-mediated endocytosis. Inside the cell, TcsL mono-O-glucosylates and thereby inactivates Rac/Cdc42 and Ras subtype GTPases, resulting in actin reorganization and an activation of p38 MAP kinase. While a role of p38 MAP kinase in TcsL-induced cell death is well established, data on a role of p38 MAP kinase in TcsL-induced actin reorganization are not available. In this study, TcsL-induced Rac/Cdc42 glucosylation and actin reorganization are differentially analyzed in p38alpha−/− MSCV empty vector MEFs and the corresponding cell line with reconstituted p38alpha expression (p38alpha−/− MSCV p38alpha MEFs). Genetic deletion of p38alpha results in reduced susceptibility of cells to TcsL-induced Rac/Cdc42 glucosylation and actin reorganization. Furthermore, SB203580, a pyridinyl imidazole inhibitor of p38alpha/beta MAP kinase, also protects
CRISPR/Cas-based genetic engineering has revolutionised molecular biology in both eukaryotes and prokaryotes. Several tools dedicated to the genomic transformation of the Clostridium genus of Gram-positive bacteria have been described in the literature; however, the integration of large DNA fragments still remains relatively limited. In this study, a CRISPR/Cas9 genome editing tool using a two-plasmid strategy was developed for the solventogenic strain Clostridium acetobutylicum ATCC 824. Codon-optimised cas9 from Streptococcus pyogenes was placed under the control of an anhydrotetracycline-inducible promoter on one plasmid, while the gRNA expression cassettes and editing templates were located on a second plasmid. Through the sequential introduction of these vectors into the cell, we achieved highly accurate genome modifications, including nucleotide substitution, gene deletion and cassette insertion up to 3.6 kb. To demonstrate its potential, this genome editing tool was used to generate a marker-free

The effect of pH, growth rate, phosphate and iron limitation, carbon monoxide, and carbon source on product formation by Clostridium pasteurianum was determined. Under phosphate limitation, glucose was fermented almost exclusively to acetate and butyrate independently of the pH and growth rate. Iron limitation caused lactate production (38 mol/100 mol) from glucose in batch and continuous culture. At 15% (vol/vol) carbon monoxide in the atmosphere, glucose was fermented to ethanol (24 mol/100 mol), lactate (32 mol/100 mol), and butanol (36 mol/100 mol) in addition to the usual products, acetate (38 mol/100 mol) and butyrate (17 mol/100 mol). During glycerol fermentation, a completely different product pattern was found. In continuous culture under phosphate limitation, acetate and butyrate were produced only in trace amounts, whereas ethanol (30 mol/100 mol), butanol (18 mol/100 mol), and 1,3-propanediol (18 mol/100 mol) were the major products. Under iron limitation, the ratio of these products ...
Clostridium cellulovorans (ATCC 35296) is anaerobic, spore forming and stain gram negative non-motile rods originally isolated from a batch methanogenic fermentation of hybrid poplar wood. C. cellulovorans is a mesophilic bacterium with optimum growth temperature of 37°C, though it can grow in a temperature range of 20 to 40°C. Optimum pH is 7.0, and the pH range of growth is 6.4 to 7.8. This organism produces extracellular enzyme complex known as cellulosome, which can degrade plant cell walls. As most abundantly available potential source of fermentable sugars in the world are the higher plants cell walls, utilization of such a vast resource for energy production would reduce the dependency on non-renewable fossil fuel. Hence, C. cellulovorans have potential industrial application for energy production. ...

Iron reduction in Gram-positive bacteria is not well understood yet, even if it has been investigated in some extent for Gram-positive bacteria. The mechanisms involved in the delivery of electrons to a solid terminal electron acceptor like iron oxides have not been defined. Clostridium acetobutylicum is an appropriate Gram-positive bacterium to study those mechanisms as genetic tools have been developed due to its industrial interest, allowing easy targeted and random mutagenesis. In this Masters project, phenotype of two mutants, whose dihydroorotate dehydrogenase 1B (pyrD) or ferredoxin hydrogenase (hydA) gene have been knocked out through ClosTron mutagenesis, have been characterized and no phenotype diverging from the wild strain has been detected. However, evidences of flavin presence in the spent growth medium have been observed during experiment. An attempt to measure their redox state, either by direct measurement or through the addition of AQDS, has been done but results are ...

Preliminary work has been done on the formulation of a new solventogenic clostridial fermentation medium based on the use of corn steep liquor (CSL). CSL is a by-product of the corn wet-milling industry, and has been used primarily as a feed supplement in the livestock industry. This nutrient-rich medium is an ideal base for use in a bacterial fermentation medium. A medium developed from CSL has been found to support good bacterial growth while allowing a level of solvent production approaching that of complex, more expensive clostridial growth media. When used in combination with C. beijerinckii, BA101, this newly developed medium holds promise to increase the cost-effectiveness of the ABE fermentation. (Abstract shortened by UMI ...

In 2000, an unusual increase of morbidity and mortality among illegal injecting drug users in the UK and Ireland was reported and Clostridium novyi was identified as the likely source of the serious infection, although infections due to C. botulinum and Bacillus cereus were also reported. Because heroin was a possibile source of infection, this study investigated the microflora of heroin samples seized in England during 2000 and 2002. Two methods were developed for the examination of the microflora of heroin. The first consisted of suspension of the drug in maximum recovery diluent (MRD) which was inoculated directly into Clostridium Botulinum Isolation Cooked Meat Broth (CBI). The second method rendered the heroin soluble in citric acid, concentrated particulate material (and bacterial cells) by filtration and removed heroin residues by washing with citric acid and phosphate-buffered saline before placing the filter in CBI broth. Duplicate CBI broths from both methods were incubated without ...

I know, not your exact words, but I felt like that was the gist of what you were saying. I had high hopes and still do, for that strain. If you have changed your mind, for some reason, could you please clarify why. Maybe any member of the clostridium family is questionable, and I might be paying for a product that is bad for me ...
Good call!. I believe you are most likely correct in your assumption. People his age are prone to an infection of the digestive track called C-Diff(Clostridium difficile) which is often contracted from a previous stay in the hospital, although a small portion of the population has this bacterium naturally present in their colon.. C-Diff is difficult to eradicate in older people because of arterial stenosis and other vascular conditions common to the elderly that lessen blood flow to certain areas and compromises their ability to fight off infection and, in general, heal. C-Diff in the very old and very infirmed is often fatal.. Wikipedia says:. Clostridium difficile (pronunciation below) (from the Greek kloster (ÎºÎ»Ï Ï Ï Î®Ï ), spindle, and Latin difficile,[1] difficult), also known as CDF/cdf, or C. diff, is a species of Gram-positive bacteria of the genus Clostridium that causes severe diarrhea and other intestinal disease when competing bacteria in the gut flora have been ...
General Information: This strain was isolated in 1924 from garden soil in Connecticut, USA, by E. Wyer and L. Rettger. It is one of the best studied solventogenic clostridia. Solvent-producing bacterium. This genus comprises about 150 metabolically diverse species of anaerobes that are ubiquitous in virtually all anoxic habitats where organic compounds are present, including soils, aquatic sediments and the intestinal tracts of animals and humans. This shape is attributed to the presence of endospores that develop under conditions unfavorable for vegetative growth and distend single cells terminally or sub-terminally. Spores germinate under conditions favorable for vegetative growth, such as anaerobiosis and presence of organic substrates. It is believed that present day Mollicutes (Eubacteria) have evolved regressively (i.e., by genome reduction) from gram-positive clostridia-like ancestors with a low GC content in DNA. This organism is a benign saccharolytic and proteolytic soil bacterium ...
In the last few years the spoilage of vacuum-packed, refrigerated beef due to psychrophilic and psychrotolerant clostridia, including production of gas inside the pack, has gained in importance. In addition to C. estertheticum and C. gasigenes, further psychrophilic clostridia have been described, which are able to cause Blown Pack Spoilage. Because there are divergent descriptions of these spoilage-causing bacteria, the phenotypic characteristics of the reference strains of six psychrotolerant clostridia were examined and the results were compared. In doing so, dissent results have been detected especially concerning hemolysis on blood agar plates as well as size of the vegeta- tive cells. The examination of C. gasigenes showed that there are distinct transverse pro- cesses in the last third of the rods of C. gasigenes, which, at present state of knowledge, have not been mentioned in the literature yet. The intention of this study was, to get more findings about the occurrence and the ...
