Corynebacterium terpenotabidum sp. nov., a bacterium capable of degrading squalene. (1/951)

The taxonomic status of Arthrobacter sp. Y-11T, which was described as a squalene-degrading bacterium, was investigated by chemotaxonomic and genetic methods. The strain possesses wall chemotype IV, MK-9(H2) as the predominant menaquinone, mycolic acids, and straight-chain, saturated and monounsaturated fatty acids, with considerable amounts of tuberculostearic acid. The DNA G+C content is 67.5 mol%. 16S rRNA gene sequence analysis and quantitative DNA-DNA hybridization experiments provided strong evidence that strain Y-11T represents a new species within the genus Corynebacterium, for which the name Corynebacterium terpenotabidum sp. nov. is proposed. The type strain of C. terpenotabidum is strain Y-11T (= IFO 14764T).  (+info)

Identification of mechanosensitive ion channels in the cytoplasmic membrane of Corynebacterium glutamicum. (2/951)

Patch-clamp experiments performed on membrane fragments of Corynebacterium glutamicum fused into giant liposomes revealed the presence of two different stretch-activated conductances, 600 to 700 pS and 1,200 to 1,400 pS in 0.1 M KCl, that exhibited the same characteristics in terms of kinetics, ion selectivity, and voltage dependence.  (+info)

Sex differences in susceptibility of ICR mice to oral infection with Corynebacterium kutscheri. (3/951)

Sex difference in susceptibility to oral infection with Corynebacterium (C.) kutscheri was experimentally studied in ICR mice. Immature (4-week-old) and adult (14-week-old) mice were inoculated with two infecting doses of C. kutscheri, and necropsied for bacteriological and serological survey 4 weeks after the bacterial infection. No macroscopic lesions at necropsy were demonstrated, except for one adult male given 10(9) bacteria. In immature mice, C. Kutscheri isolated from the oral cavity and cecum with FNC agar, were recovered in only 40.0% of female mice but in 90.0% of male mice given 10(6) bacteria (p < 0.05), and in only 55.6% of female mice but in 80.0% male mice given 10(8) bacteria. In adult mice given 10(9) bacteria, the organism were recovered in only 45.5% of female mice but in 90.9% of male mice (p < 0.05), furthermore, the mean number of organisms in the cecum of male mice harboring the organism was significantly higher than that in females (p < 0.01). Castration caused an increase in host resistance in adult male mice. These results indicated that ICR male mice were more susceptible than females, in terms of bacterial colonization in the cecum and the oral cavity, to oral infection with C. kutscheri.  (+info)

Identification of nonlipophilic corynebacteria isolated from dairy cows with mastitis. (4/951)

Nonlipophilic corynebacteria associated with clinical and subclinical mastitis in dairy cows were found to belong to four species: Corynebacterium amycolatum, Corynebacterium ulcerans, Corynebacterium pseudotuberculosis, and Corynebacterium minutissimum. These species may easily be confused. However, clear-cut differences between C. ulcerans and C. pseudotuberculosis were found in their acid production from maltotriose and ethylene glycol, susceptibility to vibriostatic agent O129, and alkaline phosphatase. Absence of growth at 20 degrees C and lack of alpha-glucosidase and 4MU-alpha-D-glycoside hydrolysis activity differentiated C. amycolatum from C. pseudotuberculosis and C. ulcerans. The mastitis C. pseudotuberculosis strains differed from the biovar equi and ovis reference strains and from caprine field strains in their colony morphologies and in their reduced inhibitory activity on staphylococcal beta-hemolysin. C. amycolatum was the most frequently isolated nonlipophilic corynebacterium.  (+info)

Cloning, sequence analysis, expression and inactivation of the Corynebacterium glutamicum pta-ack operon encoding phosphotransacetylase and acetate kinase. (5/951)

The Corynebacterium glutamicum ack and pta genes encoding the acetate-activating enzymes acetate kinase and phosphotransacetylase were isolated, subcloned on a plasmid and re-introduced into Corynebacterium glutamicum. Relative to the wild-type, the recombinant strains showed about tenfold higher specific activities of both enzymes. Sequence analysis of a 3657 bp DNA fragment revealed that the ack and pta genes are contiguous in the corynebacterial chromosome, with pta upstream and the last nucleotide of the pta stop codon (TAA) overlapping the first of the ack start codon (ATG). The predicted gene product of pta consists of 329 amino acids (Mr 35242), that of ack consists of 397 amino acids (Mr 43098) and the amino acid sequences of the two polypeptides show up to 60 % (phosphotransacetylase) and 53% (acetate kinase) identity in comparison with respective enzymes from other organisms. Northern (RNA) blot hybridizations using pta- and ack-specific probes and transcriptional cat fusion experiments revealed that the two genes are transcribed as a 2.5 kb bicistronic mRNA and that the expression of this operon is induced when Corynebacterium glutamicum grows on acetate instead of glucose as a carbon source. Directed inactivation of the chromosomal pta and ack genes led to the absence of detectable phosphotransacetylase and acetate kinase activity in the respective mutants and to their inability to grow on acetate. These data indicate that no isoenzymes of acetate kinase and phosphotransacetylase are present in Corynebacterium glutamicum and that a functional acetate kinase/phosphotransacetylase pathway is essential for growth of this organism on acetate.  (+info)

Expression of the Corynebacterium glutamicum panD gene encoding L-aspartate-alpha-decarboxylase leads to pantothenate overproduction in Escherichia coli. (6/951)

The Corynebacterium glutamicum panD gene was identified by functional complementation of an Escherichia coli panD mutant strain. Sequence analysis revealed that the coding region of panD comprises 411 bp and specifies a protein of 136 amino acid residues with a deduced molecular mass of 14.1 kDa. A defined C. glutamicum panD mutant completely lacked L-aspartate-alpha-decarboxylase activity and exhibited beta-alanine auxotrophy. The C. glutamicum panD (panDC. g.) as well as the E. coli panD (panDE.c.) genes were cloned into a bifunctional expression plasmid to allow gene analysis in C. glutamicum as well as in E. coli. The enhanced expression of panDC.g. in C. glutamicum resulted in the formation of two distinct proteins in sodium dodecyl sulfate-polyacrylamide gel electrophoresis, leading to the assumption that the panDC.g. gene product is proteolytically processed into two subunits. By increased expression of panDC.g. in C. glutamicum, the activity of L-aspartate-alpha-decarboxylase was 288-fold increased, whereas the panDE.c. gene resulted only in a 4-fold enhancement. The similar experiment performed in E. coli revealed that panDC.g. achieved a 41-fold increase and that panDE.c. achieved a 3-fold increase of enzyme activity. The effect of the panDC.g. and panDE.c. gene expression in E. coli was studied with a view to pantothenate accumulation. Only by expression of the panDC.g. gene was sufficient beta-alanine produced to abolish its limiting effect on pantothenate production. In cultures expressing the panDE.c. gene, the maximal pantothenate production was still dependent on external beta-alanine supplementation. The enhanced expression of panDC.g. in E. coli yielded the highest amount of pantothenate in the culture medium, with a specific productivity of 140 ng of pantothenate mg (dry weight)-1 h-1.  (+info)

Microbiological degradation of bile acids. The conjugation of a certain cholic acid metabolite with amino acids in Corynebacterium equi. (7/951)

1. (4R)-4[4alpha-(2-Carboxyethyl)-3aalpha-hexahydro-7abeta-methyl-5-oxoindan-1beta-y l]valeric acid (II) could not be utilized by Arthrobacter simplex, even though the acid was one of the metabolites formed from cholic acid (I) by this organism. Therefore the further degradation of the acid (II) by Corynebacterium equi was investigated to identify the intermediates involved in the cholic acid degradation. 2. The organism, cultured in a medium containing the acid (II) as the sole source of carbon, produced unexpected metabolites, the conjugates of this original acid (II) with amino acids or their derivatives, although the yield was very low. These new metabolites were isolated and identified by chemical synthesis as the Na-((4R)-4-[4alpha-(2-carboxyethyl)-3a alpha-hexahydro-7a beta-methyl-5-oxoindan-1 beta-yl]-valeryl) derivatives of L-alanine, glutamic acid, O-acetylhomoserine and glutamine, i.e. compounds (IIIa), (IIIb), (IIId) respectively. 3. The possibility that the bacterial synthetic reaction observed in the acid (II) metabolism with C. equi is analogous to peptide conjugation known in both animals and higher plants is discussed. A possible mechanism for this bacterial conjugation is also considered.  (+info)

Site-specific integration of corynephage phi16: construction of an integration vector. (8/951)

Phi16, a temperate phage induced from Corynebacterium glutamicum ATCC 21792, lysogenizes its host via site-specific recombination. The phage attachment site, attP, was located to a 6.5 kb BamHI fragment of the phi16 genome. This fragment also contained phi16 integrative functions. The minimal phage DNA fragment required for integration was defined. This 1630 bp region contained a large open reading frame, int, encoding a protein of 416 amino acids with similarity in its carboxyl-terminal domain to tyrosine recombinases and particularly to the Xer recombinases. The comparison of the nucleotide sequences of attB, attL, attR, and attP identified a common 29 bp sequence, the core sequence. It lies 11 bp downstream of the 3' end of the integrase gene. phi16 integrase was shown to catalyse site-specific integration in trans to attP with an efficiency of 5x10(3) integrants per microg DNA. The integrating fragment catalysed integration in several Corynebacterium strains that are not infected by phi16, thus enlarging the host spectrum of integrating vectors derived from phi16. In these strains, the phi16 attB site was located in a conserved intergenic region and lies downstream of a clp gene.  (+info)

Corynebacterium amycolatum is a Gram-positive, nonspore-forming, aerobic or facultatively anaerobic bacillus capable of fermentation with propionic acid as the major end product of its glucose metabolism. One of its best known relatives is Corynebacterium diphtheriae, the causative agent of diphtheria. C. amycolatum is a common component of the natural flora found on human skin and mucous membranes, and as such, is often disregarded by physicians as a contaminant when found in blood cultures. However, C. amycolatum is actually an opportunistic pathogen capable of causing serious human disease such as endocarditis and sepsis. First described in 1988, C. amycolatum is one of the diphtheroids most often isolated from clinical samples. However, it is often difficult to differentiate from other fermentative corynebacteria such as C. minutissimum and C. xerosis, both of which are known human pathogens. One method of differentiation, however, is by observing the cell wall. Unlike other members of this ...

An increasing body of evidence indicates that nondiphtheria corynebacteria may be responsible for respiratory tract infections. We report an outbreak of Corynebacterium pseudodiphtheriticum infection in children with cystic fibrosis (CF). To identify 18 C. pseudodiphtheriticum strains isolated from 13 French children with CF, we used molecular methods (partial rpoB gene sequencing) and matrix-assisted laser desorption ionization time-of-flight (MALDI-TOF) mass spectrometry. Clinical symptoms were exhibited by 10 children (76.9%), including cough, rhinitis, and lung exacerbations. The results of MALDI-TOF identification matched perfectly with those obtained from molecular identification. Retrospective analysis of sputum specimens by using specific real-time PCR showed that ≈20% of children with CF were colonized with these bacteria, whereas children who did not have CF had negative test results. Our study reemphasizes the conclusion that correctly identifying bacteria at the species level facilitates

More specific detection methods in recent years have allowed further investigation of the coryneform bacterias.C macginleyi was first identified in 1995 by Riegel et al 5-7 during investigations on lipophilic corynebacteria. It has been uniquely isolated from ocular surfaces. The first 18 cases ofC macginleyi conjunctivitis have been detected in Switzerland.8 Within the recent past we found in 10 patients 13 cases of C macginleyiconjunctivitis in Germany, indicating that the presence of this micro-organism is not geographically limited..

1. The major free lipids of Corynebacterium aquaticum were characterized as dimannosyl diglyceride, monomannophosphoinositide and phosphatidylethanolamine. Bisphosphatidylglycerol and phosphatidylglycerol were also tentatively identified. 2. We regard this as the only well-documented case of an organism containing monomannophosphoinositide to the exclusion of dimannophosphoinositides and the higher homologues. 3. The co-existence of the two mannolipids in one organism is a distinctive feature. So also is the presence of phosphatidylethanolamine in a corynebacterium. 4. The monomannophosphoinositide apparently does not utilize phosphatidylinositol as a precursor, unlike the monomannophosphoinositide of Propionibacterium shermanii. CDP-diglyceride may be necessary for its synthesis.. ...

Introduction: Coryneform or the nondiphtherial Corynebacterium species remains a neglected group as contaminants. Theseorganisms havebeen associated with invasive disease, particularly in immunocompromised patients. Species like Corynebacterium amycolatum, Corynebacterium jeikeium , Corynebacterium minutissimum and Corynebacterium urealyticum are reported with increasing frequency. An alarming rate of antibiotic resistance is also documented among such organisms.

They were subjected to Grams staining and ...
Specific bacterial commensals demonstrating multidrug resistance (MDR) are opportunistic pathogens for immunocompromised patients, including Corynebacterium species (spp.). Severe infections due to MDR corynebacteria are being increasingly reported where several MDR phenotypes have been described. One such phenotype, the macrolide-lincosamide-streptogramin B phenotype (MLSB), is characterized by high-level resistance to macrolides, lincosamides, and streptogramin B. Resistance is thought to be attributable to acquisition of the ermX gene, a methyltransferase that alters the ribosomal macrolide binding site. Until recently, ermX had been reported in only six Corynebacterium spp. We have observed other corynebacteria can also display high-level resistance to MLSB antimicrobials and are ermX positive. Hypotheses being tested include: 1) high-level macrolide and lincosamide resistance in Corynebacterium spp. is caused by acquiring ermX; 2) distribution of ermX is more widespread than previously ...
Background: Toxigenic Corynebacterium ulcerans can cause a diphtheria-like illness in humans and have been found in domestic animals, which were suspected to serve as reservoirs for a zoonotic transmission. Additionally, toxigenic C. ulcerans were reported to take over the leading role in causing diphtheria in the last years in many industrialized countries. Methods: To gain deeper insights into the tox gene locus and to understand the transmission pathway in detail, we analyzed nine isolates derived from human patients and their domestic animals applying next generation sequencing and comparative genomics. Results: We provide molecular evidence for zoonotic transmission of C. ulcerans in four cases and demonstrate the superior resolution of next generation sequencing compared to multi-locus sequence typing for epidemiologic research. Additionally, we provide evidence that the virulence of C. ulcerans can change rapidly by acquisition of novel virulence genes. This mechanism is exemplified by an ...

We conducted molecular typing of a Corynebacterium ulcerans isolate from a woman who died in Japan in 2016. Genomic DNA modification might have affected the isolates ribotyping profile. Multilocus sequence typing results (sequence type 337) were more accurate. Whole-genome sequencing had greater ability to discriminate lineages at high resolution.
Corynebacterium jeikeium, a resident of human skin, is often associated with multidrug resistant nosocomial infections in immunodepressed patients. C. jeikeium K411 belongs to mycolic acid-containing actinomycetes, the mycolata and contains a channel-forming protein as judged from reconstitution experiments with artificial lipid bilayer experiments. The channel-forming protein was present in detergent treated cell walls and in extracts of whole cells using organic solvents. A gene coding for a 40 amino acid long polypeptide possibly responsible for the pore-forming activity was identified in the known genome of C. jeikeium by its similar chromosomal localization to known porH and porA genes of other Corynebacterium strains. The gene jk0268 was expressed in a porin deficient Corynebacterium glutamicum strain. For purification temporarily histidine-tailed or with a GST-tag at the N-terminus, the homogeneous protein caused channel-forming activity with an average conductance of 1.25 nS in 1M KCl ...

An attempt was made by the authors to survey the distribution of C. renale in apparently healthy Korean male cattle and dairy cattle, and to determine the types of C. renale isolated in Korea. A total of 153 urine samples and 240 vaginal smears were collected from 253 cows for examination, and 124 urine samples of Korean cattle were investigated. Of them, one case showed cystitis symptoms. The results obtained are summarized as follows: 1. The organism was detected from 8(6.5%) of 124 specimens of Korean cattle. The isolates studied in this survey belonged to type I (4.1%), type III (1.6%) and untypable(0.8%) of C. renale. 2. The rate of isolation of C. renale was 7.5% (19 of 253 individuals) in apparently healthy cow. The 26 strains isolated from the 19 dairy cattle belonged to type I (38.5%), type II (26.9%), type III (24.6%) and untypable(11.5%) in the serological classification. From the cow with clinical cystitis, type III strain was isolated. 3. It appears that the isolation rate depends on

Glycolysis is the process of converting glucose into pyruvate and generating small amounts of ATP (energy) and NADH (reducing power). It is a central pathway that produces important precursor metabolites: six-carbon compounds of glucose-6P and fructose-6P and three-carbon compounds of glycerone-P, glyceraldehyde-3P, glycerate-3P, phosphoenolpyruvate, and pyruvate [MD:M00001]. Acetyl-CoA, another important precursor metabolite, is produced by oxidative decarboxylation of pyruvate [MD:M00307]. When the enzyme genes of this pathway are examined in completely sequenced genomes, the reaction steps of three-carbon compounds from glycerone-P to pyruvate form a conserved core module [MD:M00002], which is found in almost all organisms and which sometimes contains operon structures in bacterial genomes. Gluconeogenesis is a synthesis pathway of glucose from noncarbohydrate precursors. It is essentially a reversal of glycolysis with minor variations of alternative paths [MD:M00003 ...

Sepsis with a previously undescribed species of Corynebacterium was documented in four patients. All patients had predisposing illness at the time of infection, three patients having leukemia in relapse and one having a porencephalic cyst and a ventriculoatrial shunt. The isolates from blood cultures had a characteristic metallic sheen when grown on blood agar. They were resistant to most antibiotics tested, including the penicillins, but were uniformly sensitive to vancomycin. Common biochemical characteristics, the metallic sheen, and the unusual antibiotic sensitivity pattern suggest that these isolates comprise a new species or group of closely related species of Corynebacterium that is capable of infection in man. ...

Cutaneous microbiota is extremely diverse. Its composition varies according to the cutaneous zone and between individuals, and its imbalance is associated with skin diseases.. Cutaneous microbiota is particularly complex, with extremely significant inter- and intra-individual variations1. It is composed of a set of microorganisms, bacteria, yeasts, viruses, and parasites. At least 19 major families of bacteria have been identified: the primary ones are Actinobacteria (Corynebacterium, etc.), Firmicutes (Staphylococcus, Streptococcus, etc.) and Proteobacteria (Acinetobacter, etc.)1,2. Among the bacterial strains present on healthy skin, the primary ones found are Corynebacterium jeikeium, Pseudomonas aeruginosa, Staphylococcus aureus and Staphylococcus epidermidis3. Microbiota composition varies based on the location, ranging from 100 microorganisms per cm2 on the back or the tips of the fingers to 106 on the forehead or in the armpits2.. This microbiota develops from birth, as a result of the ...
Corynebacterium glutamicum is together with C. callunae and C. efficiens a member of the diverse group of mycolic-acid containing actinomycetes, the mycolata. These bacteria are potent producer of glutamate, lysine and other amino acids on industrial scale. The cell walls of most actinomycetes contain besides an arabinogalactan-peptidoglycan complex large amounts of mycolic acids. This three-layer envelope is called MAP (mycolyl-arabinogalactan-peptidoglycan) complex and it represents a second permeability barrier beside the cytoplasmic membrane similar to the outer membrane of Gram-negative bacteria. In analogy to the situation in the outer membrane of Gram-negative bacteria, channels are present in the mycolic acid layer of the mycobacterial cell wall for the passage of hydrophilic solutes. Molecular studies have provided far-reaching findings on the amino acid flux and its balance in C. glutamicum in general, but the L-glutamate export still remains unknown. The properties of the outer ...

This one came off as Clostridium ...
The antibiotic activity of three kinds of chitosans with different molecular weight(50, 100, 200 kD) and same deacelylated degree(85%), was evaluated against some bacteria(Staphyloccus aurueus, Pseudomonas aeruginosa, Bacillus subtilis, Corynebacterium minutissimum, Escherichia coli, Candida albillus).The growth of all the bacteria tested were inhibited by chitosans treatments, and the inhibiting rate decreased with the rising of chitosans molecular weight. The minimum inhibitory concentration of all the chitosans is above 0.5 g/L. The effects of temperature, metal ions on the antibiotic activity of chitosans were also assessed.
Kata Wikipedia, MSG adalah bentuk garam natrium dari asam glutamat. Asam glutamat sendiri termasuk golongan asam amino nonesensial. US FDA (BPOM-nya Amerika) memasukkan MSG dalam golongan Generally Recognized as Safe (GRAS), sedangkan Uni Eropa menggolongkannya sebagai tambahan makanan alias food additive. Reputasi buruk MSG dimulai sejak tahun 60-an, ketika beberapa artikel dalam berkala ilmiah melaporkan temuan adanya kerusakan otak dan obesitas yang terkait pemberian MSG pada mencit dan monyet. Satu dekade kemudian muncul beberapa laporan yang meng-counter temuan tersebut. Penelitian selanjutnya membuktikan bahwa efek kerusakan otak akibat pemberian MSG hanya terjadi pada kelompok rodensia, seperti tikus dan mencit, saja. Informasi-informasi ini bisa dibaca di laman googlescholar.. Saat ini MSG diproduksi dengan menggunakan teknologi fermentasi, biasanya menggunakan bantuan bakteri Corynebacterium sp dengan substrat berbagai jenis gula, mulai dari gula bit hingga molase tebu sisa produksi ...

We describe the first reported case of Corynebacterium striatum (C. striatum) relapsing bacteraemia in a patient with peripheral arterial disease and proven Corynebacterium species colonization of a chronic foot ulcer, focusing on the difficulties in the management of the patient. We conclude that the optimal duration of the antibiotic treatment for relapsing C. striatum bacteraemia from a chronic ulcer should be 6 weeks together with surgical treatment.. Key words: Corynebacterium striatum, antibiotic treatment, peripheral arterial disease, relapsing bacteraemia, skin infection. Corynebacterium species other than Corynebacterium diphteriae are part of the normal flora of human skin and mucous membranes (Coyle and Lipsky, 1990). Corynebacterium striatum (C. striatum), a gram-positive bacillus, was traditionally regarded to be a colonizer or a contaminant (Watkins et al., 1993). The first published case of C. striatum infection was in 1980 in an immunocompromised patient with pleuropulmonary ...
The surface (S)-layer gene region of the Gram-positive bacterium Corynebacterium glutamicum ATCC 14067 was identified on fosmid clones, sequenced and compared with the genome sequence of C. glutamicum ATCC 13032, whose cell surface is devoid of an ordered S-layer lattice. A 5-97 kb DNA region that is absent from the C. glutamicum ATCC 13032 chromosome was identified. This region includes cspB, the structural gene encoding the S-layer protomer PS2, and six additional coding sequences. PCR experiments demonstrated that the respective DNA region is conserved in different C. glutamicum wild-type strains capable of S-layer formation. The DNA region is flanked by a 7 bp direct repeat, suggesting that illegitimate recombination might be responsible for gene loss in C. glutamicum ATCC 13032. Transfer of the cloned cspB gene restored the PS2(-) phenotype of C. glutamicum ATCC 13032, as confirmed by visualization of the PS2 proteins by SDS-PAGE and imaging of ordered hexagonal S-layer lattices on living ...
Corynebacterium striatum is a member of the non-diphtherial corynebacteria, which are ubiquitous in nature and generally colonize the skin and mucous membranes of humans. Rarely, it causes infective endocarditis (IE). We report a case of rare left atrial bacterial vegetative mass due to C. striatum masquerading as a myxoma identified through a tortuous diagnostic process, and present a brief review of the relevant literature. We present a case of 63-year-old man who presented with progressively worsening dyspnea on exertion and lower leg edema, and was diagnosed with heart failure. Transesophageal echocardiography (TEE) revealed that the left atrium was filled with a 2.7 cm × 2.6 cm mass. The patient, who had no signs of infection or related risk factors, was suspected of having a left atrial myxoma clinically. After excising the mass, the histopathology suggested thrombus with no myxocytes. Postoperatively, a fever appeared and C. striatum was isolated from the blood
Diphtheria toxin (DT) is produced by toxigenic strains of the human pathogen Corynebacterium diphtheriae as well as zoonotic C. ulcerans and C. pseudotuberculosis. Toxigenic strains may cause severe respiratory diphtheria, myocarditis, neurological damage or cutaneous diphtheria. The DT encoding tox gene is located in a mobile genomic region and tox variability between C. diphtheriae and C. ulcerans has been postulated based on sequences of a few isolates. In contrast, species-specific sequence analysis of the diphtheria toxin repressor gene (dtxR), occurring both in toxigenic and non-toxigenic Corynebacterium species, has not been done yet. We used whole genome sequencing data from 91 toxigenic and 46 non-toxigenic isolates of different pathogenic Corynebacterium species of animal or human origin to elucidate differences in extracted DT, DtxR and tox-surrounding genetic elements by a phylogenetic analysis in a large sample set. Sequences of both DT and DtxR, extracted from whole genome sequencing data,
The genus Corynebacterium is composed of Gram-positive bacteria that are widely distributed throughout the environment; these bacteria are also part of the normal microbiota of human skin and mucous membranes. Multiple studies have shown that species of this genus, including C. striatum, become pathogenic to humans under special conditions. Our aim was to determine the characteristics of clinical multiresistant strains of C. striatum that were isolated in our geographical region, to determine their diversity, and to compare them with the type strain and with related species. We studied fifty-two strains of C. striatum isolated from different hospitals from Mallorca, Spain, mainly from the Hospital Joan March in Bunyola, Mallorca. Most of the strains were isolated from sputum cultures of respiratory samples from patients with chronic obstructive pulmonary disease. To gain further insight into the genetic diversity of the strains, we analysed several housekeeping genes and other genes associated with

The secondary glycine-betaine transporter BetP is one of four osmoregulated carriers, which mediate the import of compatible solutes in the Gram-positive soil bacterium Corynebacterium glutamicum under hyperosmotic conditions. BetP serves both as an osmosensor and osmoregulator. Thus the protein has the ability to sense osmotic stress and to regulate its catalytic activity in dependence of the given stress situation. Investigations in proteoliposomes had shown that an elevated internal K+ concentration is the specific stimulus for BetP activation in vitro. In this work a stimulus for an osmosensor identified in vitro could be verified in vivo for the first time, as it was shown that BetP activity depends also in living cell on the presence of potassium. However, the in vivo measurements indicated that beyond K+ a second stimulus is required for osmoresponsive BetP-activation in living cells. It was known that the cytoplasmic C-terminal BetP-domain is essential for potassium sensing. Using ...
Background Methanol is present in most ecosystems and may also occur in industrial applications, e.g. as an impurity of carbon sources such as technical glycerol. Methanol often inhibits growth of bacteria, thus, methanol tolerance may limit fermentative production processes. Results The methanol tolerance of the amino acid producing soil bacterium Corynebacterium glutamicum was improved by experimental evolution in the presence of methanol. The resulting strain Tol1 exhibited significantly increased growth rates in the presence of up to 1 M methanol. However, neither transcriptional changes nor increased enzyme activities of the linear methanol oxidation pathway were observed, which was in accordance with the finding that tolerance to the downstream metabolites formaldehyde and formate was not improved. Genome sequence analysis of strain Tol1 revealed two point mutations potentially relevant to enhanced methanol tolerance: one leading to the amino acid exchange A165T of O-acetylhomoserine ...

Trypsin-like activity (TLA), clinical parameters and TLA-postitive bacteria were examined in periodontitis and healthy sites in dogs. TLA was markedly higher in periodontitis than at healthy sites. There was good correlation between TLA positivity and severity of periodontal disease. The proportions of TLA-positive bacteria to total isolates in periodontitis and healthy sites were 21.1% and 2.1%, respectively. Among TLA-positive bacteria in periodontitis sites, 4.4% showed strong TLA activity, 35.3% showed moderate and 60.3% showed weak activity. In the healthy sites, all the TLA-positive bacteria showed weak activity. In all, 90% of the total number of TLA-positve bacteria were identified as belonging to the family Actinomycetaceae; 40% of bacteria belonging to the family Actinomycetaceae were identified as genus Corynebacterium with moderate trypsin-like activity and the remaining 60% were identified as genus Actinomyces with weak activity. Obligately anaerobic bacteria accounted for only 5.9% of the
The function of starch phosphorylase has long been debated on the regulation of starch metabolism during the growth and development of plants. In this study, we isolated starch phosphorylase genes (Pho1 and Pho2) from barley, characterized their gene and protein structures, predicated their promoters cis-elements and analyzed expression patterns. Multiple alignments of these genes showed that (1) both Pho1 and Pho2 genes possess 15 exons and 14 introns in all but three of the species analyzed, Aegilops tauschii (for Pho1 which contains 16 exons and 15 introns), potato (for Pho1b which contains 14 exons and 13 introns), and Triticum uraru (for Pho2 which contains 15 exons and 14 introns); (2) the exon-intron junctions of Pho1 and Pho2 flanking the ligand-binding sites are more conservative than the other regions. Analysis of protein sequences revealed that Pho1 and Pho2 were highly homologous except for two regions, the N terminal domain and the L78 insertion region. The results of real-time ...
Resistance to arsenite (As(III)) by cells is generally accomplished by arsenite efflux permeases from Acr3 or ArsB unrelated families. We analyzed the function of three Acr3 proteins from Corynebacterium glutamicum, CgAcr3-1, CgAcr3-2, and CgAcr3-3. CgAcr3-1 conferred the highest level of As(III) resistance and accumulation in vivo. CgAcr3-1 was also the most active when everted membranes vesicles from Escherichia coli or C. glutamicum mutants were assayed for efflux with different energy sources. As(III) and antimonite (Sb(III)) resistance and accumulation studies using E. coli or C. glutamicum arsenite permease mutants clearly show that CgAcr3-1 is specific for As(III). In everted membrane vesicles expressing CgAcr3-1, dissipation of either the membrane potential or the pH gradient of the proton motive force did not prevent As(III) uptake, whereas dissipation of both components eliminated uptake. Further, a mutagenesis study of CgAcr3-1 suggested that a conserved cysteine and glutamate are ...
The influence of pH and inoculum size on phenol utilization by bacterial isolates from oil refinery effluent was investigated. The substrate used for the assessment was phenol, which formed a model substrate for the experiment. Phenol was progressively degraded at pH range of 6.3 to 8.0. Maximum phenol degradation by Bacillus sp. RBD1 and Corynebacterium sp. RBD2 was obtained at pH value of 7.1. Conversely, utilization of phenol at pH 5.5 was significantly high for both organisms. Phenol was degraded at every cell density (inoculum size) tested with the two organisms but phenol degradation rate increased with increasing inoculum size. Cultures of Bacillus sp. RBD1 and Corynebacterium sp.RBD2 with the lowest cell densities exhibited highest specific rate of utilization of phenol. The results obtained indicated lower phenol utilization rate per colony forming unit at higher cell density. It was also found that pH 6.3 to 8.0 was found to be optimal for phenol degradation by the test organisms ...

With the recent success of the heterologous expression of mycobacterial antigens in corynebacteria, in addition to the importance of these bacteria in biotechnology and medicine, a better understanding of the structure of their cell envelopes was needed. A combination of molecular compositional analysis, ultrastructural appearance and freeze-etch electron microscopy study was used to arrive at a chemical model, unique to corynebacteria but consistent with their phylogenetic relatedness to mycobacteria and other members of the distinctive suprageneric actinomycete taxon. Transmission electron microscopy and chemical analyses showed that the cell envelopes of the representative strains of corynebacteria examined consisted of (i) an outer layer composed of polysaccharides (primarily a high-molecular-mass glucan and arabinomannans), proteins, which include the mycoloyltransferase PS1, and lipids; (ii) a cell wall glycan core of peptidoglycan-arabinogalactan which may contain other sugar residues and was
l-Ornithine, a non-essential amino acid, has enormous industrial applications in food, pharmaceutical, and chemical industries. Currently, l-ornithine production is focused on microorganism fermentation using Escherichia coli or Corynebacterium glutamicum. In C. glutamicum, development of high l-ornithine producing C. glutamicum was achieved by deletion of argF, but was accompanied by growth deficiency and arginine auxotrophy. l-Arginine has been routinely added to solve this problem; however, this increases production cost and causes feedback inhibition of N-acetyl-l-glutamate kinase activity. To avoid the drawbacks of growth disturbance due to disruption of ArgF, strategies were adopted to attenuate its expression. Firstly, ribosome binding site substitution and start codon replacement were introduced to construct recombinant C. glutamiucm strains, which resulted in an undesirable l-ornithine production titer. Then, we inserted a terminator (rrnB) between argD and argF, which significantly improved l

N2 - The contribution of activated macrophages to protection against Escherichia coli was studied in mice treated intravenously with Corynebacterium parvum 7 days before infection. C. parvum‐treated mice showed increased phagocytic activity and enhanced resistance to Listeria infection. In contrast, these mice showed increased susceptibility to a subsequent challenge with E. coli that correlated closely with a reduction in the LD50 of lipopolysaccharide (LPS) in these mice. The peritoneal macrophages obtained from C. parvum‐treated mice had a strong ability to phagocytize and kill E. coli in in vitro experiments. A rapid decline in the number of bacteria in the liver of C. parvum‐treated mice was observed in the early period of infection. However, the number ...

As the criteria for patient selection and drugs used were similar, we have pooled the data to analyze the effects of these two treatments. Both studies used BCG (Tice, Chicago, IL) 3 x 108 live organisms per treatment by Tine technique and C parvum (Burroughs-Wellcome, Triangle Park, NC) subcutaneous at a dose of 4 mg/m2 (SECSG) or 5 μg/m2 (Hershey) per treatment. The only difference in these studies was the frequency of immunization, ...
The construction of microbial cell factories requires cost-effective and rapid strain development through metabolic engineering. Recently, RNA-guided CRISPR technologies have been developed for metabolic engineering of industrially-relevant host. To demonstrate the application of the CRISPR interference (CRISPRi), we developed two-plasmid CRISPRi vectors and applied the CRISPRi in Corynebacterium glutamicum to repress single target genes and double target genes simultaneously. Four-different single genes (the pyc, gltA, idsA, and glgC genes) repressions were successfully performed using the CRISPRi vectors, resulting significant mRNA reductions of the targets compared to a control. Subsequently, the phenotypes for the target gene-repressed strains were analyzed, showing the expected cell growth behaviors with different carbon sources. In addition, double gene repression (the idsA and glgC genes in a different order) by the CRISPRi resulted in an independent gene repression to each target gene

Previously, we showed that C. glutamicum mycothiol peroxidase MPx, similar to the glutathione peroxidase (Gpx), was resistant to and induced by organic and inorganic peroxides [55]. Moreover, E. faecium gpx is regulated by MarR-type AsrR [44]. Thus, we suggested C. glutamicum MPx was regulated by CosR. The lacZ activity of Pmpx::lacZ chromosomal promoter fusion reporter in relevant C. glutamicum strains and quantitative real-time PCR (qRT-PCR) profiling of mpx expression were quantitatively measured in bacterial cells either untreated or treated with different toxic agents of various concentrations (Figure 5A,B). Concentrations of CHP applied were able to reduce the growth rate but under sub-lethal concentrations (Supplementary Figure S5). As expected, high levels of the promoter lacZ activity of mpx were detected in the ΔcosR strain, regardless of whether or not CHP was present. Under normal conditions (without CHP treatment), the promoter lacZ activity of mpx in ΔcosR strain was 6.5 times ...

As a gram-positive bacterium with good genomic stability, C. glutamicum is more difficult to engineer than genetically tractable hosts such as E. coli [40, 48]. CRISPR/Cas9-mediated ssDNA recombineering was developed for deleting 400 bp chromosomal fragment in C. glutamicum in the time this manuscript was being prepared [35]. However, gene deletion and insertion with plasmid-borne editing templates that are key enabling techniques for reconstruction and integration of metabolic pathways are still in demand. In this study, a tailor-made CRISPR/Cas9 toolbox was developed for efficient and comprehensive engineering of C. glutamicum. Notably, gene deletion and insertion with plasmid-borne editing templates were efficiently implemented. Moreover, single-nucleotide editing and double-locus editing were achieved at efficiencies of 90.0 and 40.0%, respectively, which will considerably accelerate precise genome editing of C. glutamicum.. S. pyogenes Cas9 is suggested to be toxic to C. glutamicum and ...
