This study showed that cultivation conditions (medium composition, initial medium pH, aeration rate, inoculum density) affect biomass and polysaccharide production in Ganoderma lucidum strain HAI 447. The synthetic medium (pH 5.5) with maltose at the concentration of 65.0 g L-1, peptone of 0.2%, as well as in the presence of K, Na, and Mg at concentrations of 6.0, 3.0, and 2.0 mM, respectively, presented the best conditions for biomass (29.2 g L-1) and extra- and intracellular polysaccharide (2.9 mg mL(-1) and 73.3 mg g(-1), respectively) production in the analyzed strain. Constant aeration was optimal for biomass and extracellular polysaccharide production, whereas cultivation under stationary conditions was the best for intracellular polysaccharide production. A peak in biomass and polysaccharide production was observed at an inoculum density of 20.0 mL ...
The genomic organization of the chromosomal cps region that is responsible for capsular polysaccharide synthesis in Klebsiella pneumoniae Chedid (O1:K2) was investigated. Deletion analyses and Southern hybridization studies suggested that the central region of the cloned 29-kb BamHI fragment is indispensable for K2 capsular polysaccharide synthesis. The 24,329-bp nucleotide sequence of the Klebsiella cps region was determined and deposited in the EMBL and GenBank databases through DDBJ and assigned accession number D21242. Nineteen possible open reading frames (ORFs) were identified in the sequenced area. Among them, 13 ORFs are very close to each other. Six of the 19 ORFs show considerable nucleotide sequence similarities to Salmonella typhimurium cpsG, cpsB, rfbP, and orf2.8, Escherichia coli gnd, and Haemophilus influenzae bexD, respectively. Moreover, the deduced amino acid sequence of the ORF10 product demonstrated a highly hydrophobic profile and showed putative membrane topology ...
Anti-polysaccharide immunity is a key facet of protection against several bacterial pathogens. Problems exist with current polysaccharide vaccines and alternative strategies that deliver a protective response are needed. We have identified immunological peptide mimics of type 6B and 9V pneumococcal capsular polysaccharides that could be used as vaccine antigens. Peptides mimicking antigenic properties of serotype 6B capsular polysaccharide were obtained from a phage-displayed peptide library expressing dodecameric peptides, using a human monoclonal antibody (Db3G9). A murine monoclonal antibody (206, F-5) against the serotype 9V capsular polysaccharide identified three peptide mimotopes from the dodecameric peptide library and one from a random pentadecameric peptide library. In ELISA, binding of 206, F-5 and Db3G9 to phage displaying the selected mimotopes was significantly inhibited by type-specific pneumococcal polysaccharide. Peptides were conjugated to keyhole limpet haemocyanin and were ...
Abs to a number of polysaccharide Ags have several common attributes: CDR-H3 is implicated in binding to Ag (28, 29), its length is strictly maintained (20, 30), and its sequence is almost invariably characterized by the presence of hydrophilic tyrosine residues (21, 31, 32). Xu and Davis (9) showed that, in VH-restricted mice, CDR-H3 diversity was sufficient for the development of specific Ab responses to a variety of hapten and protein Ags but not for two bacterial polysaccharide Ags. The latter finding was attributed to the failure of the single VH gene in their mouse model to accommodate the polysaccharide-specific response, which suggested VH dependency. Work by Nakouzi and Casadevall (33) showed that, in addition to CDR-H3, CDR-H2 encoded amino acids critical for the generation of Abs specific for the polysaccharide galactoxylomannan. These studies highlighted the significant roles that both the VH, as a whole, and the CDR component of the VH, as a part, can play in the generation of ...
Tumor cells that acquire metastatic potential have developed resistance to anoikis, a cell death process, after detachment from their primary site to the second organ. In this study, we investigated the molecular mechanisms of a novel marine bacterial polysaccharide EPS11 which exerts its cytotoxic effects through affecting cancer cell adhesion and anoikis. Firstly, we found that EPS11 could significantly affect cell proliferation and block cell adhesion in A549 cells. We further demonstrated that the expression of several cell adhesion associated proteins is downregulated and the filiform structures of cancer cells are destroyed after EPS11 treatment. Interestingly, the destruction of filiform structures in A549 cells by EPS11 is in a dose-dependent manner, and the inhibitory tendency is very consistent with that observed in the cell adhesion assay, which confirms that filiform structures play important roles in modulating cell adhesion. Moreover, we showed that EPS11 induces apoptosis of A549 ...

Erythrocytes coated with bacterial capsular polysaccharides, notably the Vi antigen, were no longer agglutinated by antibodies directed against the various antigens native to the red cell surface. These effects could not be attributed to prevention of antibody uptake even though in some systems the uptake of antibody was diminished. In fact, agglutination by Rh-incomplete antibody was brought back to the original titer only after the sensitized Vi-coated cells had been subjected to ten alternating exposures to globulin and antiglobulin. Hemagglutination by Newcastle, mumps, and influenza viruses was also suppressed. Erythrocytes coated with Vi polysaccharide assumed the distinctive physicochemical attributes of this acidic polymer which results in a stabilization of the erythrocyte suspension as manifested by increased electrophoretic mobility and a striking decrease in the rate of sedimentation. Among the possible models for explaining the nature of the Vi effect on immune agglutination, the ...
Polysaccharide antigens are T cell-independent antigens, and do not induce immune B cell memory. Consequently, vaccines based on polysaccharides have limited clinical usefulness and induce short-lasting antibody responses in adults. Their immunogenicity can be enhanced by conjugation to an immunogenic carrier protein, generating T cell-dependent glycoconjugate antigens able to induce immunological memory. However, these glycoconjugates suffer from some problems. Recent investigations have found a group of structurally distinct bacterial polysaccharides able to activate T cells in vivo and in vitro. They present a zwitterionic charge motif distributed along the chain and, for this reason, they are called zwitterionic polysaccharides (ZPSs). This zwitterionic charge motif is believed to be responsible for their particular immunological behavior. The integrity of the zwitterionic motif is essential for the biological activity of ZPS. However, it must be clarified if the introduction of the ...
The capsular polysaccharide (SIII) of type III pneumococci was removed enzymatically, and the cells thus deprived of preformed SIII were washed and examined for capacity to synthesize SIII anew. The washed, decapsulated cocci lost their capacity to be agglutinated in type-specific antiserum but again became agglutinable and formed readily measurable amounts of SIII, after suspension in a solution containing only glucose and salts.. Maximal SIII synthesis required the presence of glucose, magnesium, potassium and phosphate ions, and oxygen. Other fermentable sugars could be substituted for glucose but then the yield of SIII was reduced. Synthesis of SIII occurred anaerobically but was increased four- to fivefold by oxygenation of the suspension. The effects of pH and of enzyme poisons on the capacity of the cocci to form SIII are described.. ...
Bacterioides fragilis is a gram-negative anaerobe and a prototypic gut commensal organism. B. fragilis is able to produce eight different capsular polysaccharides, which envelope the organism and form its protective capsule. Polysaccharide A (PSA) is one of these polysaccharides and, interestingly, has a unique zwitterionic motif that includes alternating positively and negatively charged sugar residues. PSA consists of a tetrasaccharide repeat unit that forms a polymer of between 30-300 repeats.. Such bacterial capsular polysaccharides are well known to industry, and are the basis of polysaccharide conjugate vaccines used successfully for decades in millions of people. The specific zwitterionic polysaccharide PSA was shown, in a series of landmark papers by our companys scientific founders that overturned established immunologic paradigms, to be processed via the endosomal pathway in antigen-presenting cells, depolymerized by NO-dependent deamination, and presented to CD4+ T-cells by MHC class ...
Totally, 142 HF patients with midrange ejection fraction (HFmrEF) and reduced ejection fraction (HFrEF) were enrolled in the study. There was a significantly correlation both between the EF and the EPSS and between the EF and the LVIDd/EPSS (P,0.001). In both HFmrEF and HFrEF groups, the correlation between the LVIDd/EPSS and the EF was more significant than was the correlation between the EPSS and the EF (P,0.001). The results of the linear regression analysis indicated that the LVIDd/EPSS was an independent predictor of the HFmrEF and the HFrEF (P,0.001). In the patients with EPSS≤12, there was a significant association between the EF and the LVIDd/EPSS (P,0.001) but not between the EF and the EPSS(P,0.05). The receiver operating characteristic curve analysis showed that the LVIDd/EPSS predicted advanced HF with 87% sensitivity and 72% specificity, using a cutoff value of 3.35,and it predicted the HFrEF (EF,40%) with 84% sensitivity and 81% specificity, using a cutoff value of 3.75.. ...

Author Summary Streptococcus pneumoniae, or pneumococcus, is an important pathogen worldwide and causes a wide range of diseases, mostly in young children and the elderly. There are 91 serotypes of pneumococcus, each of which produces a unique polysaccharide, called the capsule, that attaches to the bacterial surface and prevents it from being cleared by the host. The serotypes differ greatly in their prevalence in the human population. There is currently a vaccine, effective in infancy, which targets seven clinically important serotypes, but several types not covered by the vaccine are beginning to increase in carriage frequency. As a result, it is critical to understand why some serotypes are frequently carried in the human population while others are not. In this study, we find that the high-prevalence serotypes tend to be more heavily encapsulated and more resistant to killing by neutrophils. Significantly, we find that the biochemical properties of the different polysaccharides can be used to
High-throughput sequencing allows detailed study of the BCR repertoire postimmunization, but it remains unclear to what extent the de novo identification of Ag-specific sequences from the total BCR repertoire is possible. A conjugate vaccine containing Haemophilus influenzae type b (Hib) and group C meningococcal polysaccharides, as well as tetanus toxoid (TT), was used to investigate the BCR repertoire of adult humans following immunization and to test the hypothesis that public or convergent repertoire analysis could identify Ag-specific sequences. A number of Ag-specific BCR sequences have been reported for Hib and TT, which made a vaccine containing these two Ags an ideal immunological stimulus. Analysis of identical CDR3 amino acid sequences that were shared by individuals in the postvaccine repertoire identified a number of known Hib-specific sequences but only one previously described TT sequence. The extension of this analysis to nonidentical, but highly similar, CDR3 amino acid ...

TY - JOUR. T1 - Molecular architectures and functional properties of gellan gum and related polysaccharides. AU - Chandrasekaran, R.. AU - Radha, A.. PY - 1995/5. Y1 - 1995/5. N2 - Certain linear and branched polysaccharides produced by unrelated species of bacteria are grouped in the gellan gum family because of their conserved backbone structures. All have excellent rheological properties and, thus, are useful in industrial applications. Physicochemical investigations of these polysaccharides in solution and structural studies of them in the solid state using X-ray diffraction have provided mutually complementary results. The study double-helix morphology that is characteristic of gellan gum prevails in other members of the gum family in spite of the presence of substituents and side chains. Association between double helices is facilitated by ions and water molecules. The observed physical properties of solutions and gels made with members of the gellan gum family can be directly rationalized ...
Bacterial polysaccharides and lipopolysaccharides of Porphyromonas gingivalis. Bacterial virulence may be enhanced by the presence of a polysaccharide capsule or by lipopolysaccharide. The polysaccharide capsules often act to inhibit phagocytosis, allowing for evasion of host defense mechanisms. Our laboratory is engaged in the study of polysaccharide and lipopolysaccharide of P. gingivalis. Polysaccharide and lipoplysaccharide are released from the bacterial cell surface and purified by a variety of techniques. The purified components are then characterized chemically and immunologically. The ability of these components to function as immunogens and as activators of the serum complement system is under investigation. Current investigations are also evaluating the association to periodontal disease and the capsular polysaccharide serotype. ...

Polysaccharides are also abundant in plant and marine sources and these are an as yet relatively untapped resource for these molecules. Isolated polysaccharides have been shown to have potent biological activities in a range of cell types and as such are a focus of identification of novel bioactive compounds for therapeutic use. Polysaccharides are under investigation for the modulation of the immune system that can be used to both reduce inflammation in certain diseases but also to potentiate inflammation which has been shown to be beneficial post-surgery. Using a range of high throughput strategies were are examining the biological roles of naturally derived polysaccharides, with a particular focus on seaweed-derived polysaccharides.. ...

The formation of heparin-precursor polysaccharide (N-acetylheparosan) was studied with a mouse mastocytoma microsomal fraction. Incubation of this fraction with UDP-[3H]GlcA and UDP-GlcNAc yielded labelled macromolecules that could be depolymerized, apparently to single polysaccharide chains, by alkali treatment, and thus were assumed to be proteoglycans. Label from UDP-[3H]GlcA (approx. 3 microM) is transiently incorporated into microsomal polysaccharide even in the absence of added UDP-GlcNAc, probably owing to the presence of endogenous sugar nucleotide. When the concentration of exogenous UDP-GlcNAc was increased to 25 microM the rate of incorporation of 3H increased and proteoglycans carrying polysaccharide chains with an Mr of approx. 110,000 were produced. Increasing the UDP-GlcNAc concentration to 5 mM led to an approx. 4-fold decrease in the rate of 3H incorporation and a decrease in the Mr of the resulting polysaccharide chains to approx. 6000 (predominant component). When both ...
The polysaccharide hydration phenomenon is nowadays the subject of intense research. The interaction of native and modified polysaccharides and polysaccharides-based bioconjugates with water has an important influence on their functional behaviour. Notwithstanding that the hydration phenomenon has been studied for decades, there is still a lack of awareness about the influence of hydration water on the polysaccharide´s structure and consequences for industrial or medicinal applications. The hydration of polysaccharides is often described by the existence of water layers differing in their physical properties depending on the distance from the polysaccharide. Using the differential scanning calorimetry (DSC) such water layers were categorized according their properties upon cooling in hyaluronan (HYA, sodium salt of ß-1,4-linked units of ß-1,3-linked D-glucuronic acid and N-acetyl-D-glucosamine), a model polysaccharide in the present work.

Linear polysaccharides are typically composed of repeating mono- or disaccharide units and are ubiquitous among living organisms. Polysaccharide diversity arises from chain-length variation, branching, and additional modifications. Structural diversity is associated with various physiological functions, which are often regulated by cognate polysaccharide-binding proteins. Proteins that interact with linear polysaccharides have been identified or developed, such as galectins and polysaccharide-specific antibodies, respectively. Currently, data is accumulating on the three-dimensional structure of polysaccharide-binding proteins. These proteins are classified into two types: exo-type and endo-type. The former group specifically interacts with the terminal units of polysaccharides, whereas the latter with internal units. In this review, we describe the structural aspects of exo-type and endo-type protein-polysaccharide interactions. Further, we discuss the structural basis for affinity and specificity
Group II K antigens such as the K5 are associated with Escherichia coli causing serious extraintestinal infections. Genes for the production of group II capsules (kps) are organised into three functional regions 1, 2 and 3. The central region 2 encodes proteins involved in the biosynthesis of type specific polysaccharide. Proteins encoded by the flanking regions 1 and 3 are involved in the export of polysaccharide across the bacterial membranes unto the cell surface. Translocation of polysaccharide across the inner membrane is mediated by two region 3 encoded proteins, KpsM and KpsT which belong to the ATP-binding cassette (ABC) superfamily of transporters. Region 1 encodes six proteins, KpsF-E-D-U-C-S. The KpsE protein was shown to localise in the inner membrane and mutants lacking the encoded protein were unable to export polysaccharide to the cell surface. To understand the export role of the KpsE, its membrane topology was determined using TnphoA mutagenesis and beta-lactamase fusions. The ...

N2 - Heterotrophic microbial communities process much of the carbon fixed by phytoplankton in the ocean, thus having a critical role in the global carbon cycle. A major fraction of the phytoplankton-derived substrates are high-molecular-weight (HMW) polysaccharides. For bacterial uptake, these substrates must initially be hydrolysed to smaller sizes by extracellular enzymes. We investigated polysaccharide hydrolysis by microbial communities during a transect of the Atlantic Ocean, and serendipitously discovered - using super-resolution structured illumination microscopy - that up to 26% of total cells showed uptake of fluorescently labelled polysaccharides (FLA-PS). Fluorescence in situ hybridisation identified these organisms as members of the bacterial phyla Bacteroidetes and Planctomycetes and the ...

Covalently modified polysaccharides are routinely used in tissue engineering due to their tailored biofunctionality. Understanding the effect of single-chain level modification on the solution conformation of the single chain, and more importantly on the self-assembly and aggregation of the ensemble of chains is expected to improve our ability to control network topology and the properties of the resulting gels. Attaching an RGD peptide to a polysaccharide backbone is a common procedure used to promote cell adhesion in hydrogel scaffolds. Recently it has been shown that the spatial presentation of the RGD sequences affects the cell behavior; thus, understanding the effects of grafted RGD on the conformational properties of the solvated polysaccharide chains is a prerequisite for rational design of polysaccharide-peptide based biomaterials. Here we investigate the effect of covalently linked G4RGDS on the conformational state of the individual chain and chain assemblies of alginate, chitosan, and ...

An amino derivative of the natural glucuronide, euxanthic acid, was prepared and coupled by the azo-link to proteins. These azo-proteins gave precipitates with type II pneumococcus antiserum, which were inhibited by glucuronides. The effect of varying azoprotein/serum ratio on the amount and com position of the precipitate was similar to the effect of varying polysaccharide/serum ratio on the precipitate form ed when the specific polysaccharide is added to the serum. Attempts to immunize rabbits and mice with a ino-euxanthic acid azoprotein were not successful. Chemical estimations and animal protection experiments indicated that the material precipitated by the azo-protein from the serum was part of the antibody to type II pneumococcus. These results support the view that at any rate part of the specificity of type II serum for the type polysaccharide is due to glucuronic acid or some closely similar grouping. ...

A broad variety of bacteria including the Rhizobiaceae are able to secrete polysaccharides. Sugar polymers that form an adherent cohesive layer on the cell surface are designated capsular polysacharides (CPS), whereas the term exopolysaccharide (EPS) is used for polysaccharides with little or no cell association. Due to the variation of monosaccharide sequences, condensation linkages and non-carbohydrate decorations, an infinite array of structures can be provided by this class of macromolecules. Different rheological properties depend on the structure and the molecular weight of EPS. These properties and the location of EPS, forming the outer layer of the cell surface, contribute to the cell protection against environmental influences, attachment to surfaces, nutrient gathering and to antigenicity (Costerton et al., 1987, Sutherland 1988, Whitfield 1988, Beveridge and Graham 1991). The structural diversity of oligosaccharides derived from EPS enables them to function additionally as ...
