Abstract
In this study, we purified and characterized exopolysaccharide (EPS) produced by a high-EPS-producing dairy starter bacterium, Streptococcus thermophilus ASCC 1275. Crude EPS was extracted from S. thermophilus ASCC 1275 and partially purified using dialysis. Further purification and fractionation of exopolysaccharide was conducted using HPLC on a Superose 6 column (Cytiva/Global Life Sciences Solutions, Marlborough, MA). Glycosyl composition analysis, linkage analysis along with 1-dimensional and 2-dimensional nuclear magnetic resonance spectroscopy were performed to deduce the structure of EPS. Three fractions (F) obtained from gel permeation chromatography were termed F1 (2.6%), F2 (45.8%), and F3 (51.6%) with average molecular weights of approximately 511, 40, and 5 kDa, respectively. Monosaccharide composition analysis revealed the dominance of glucose, galactose, and mannose in all 3 fractions. Major linkages observed in F3 were terminal galactopyranosyl (t-Gal), 3-linked glucopyranosyl (3-Glc), 3-linked galactofuranosyl (3-Galf), and 3,6-linked glucopyranosyl (3,6-Glc) and major linkages present in F2 were 4-Glc (48 mol%), followed by terminal mannopyranosyl (t-Man), 2- + 3-linked mannopyranosyl (2-Man+3-Man), and 2,6-linked mannopyranosyl (2,6-Man; total ∼28 mol%). The 1-dimensional and 2-dimensional nuclear magnetic resonance spectroscopy revealed that F2 comprised mannans linked by (1→2) linkages and F3 consisted of linear chains of α-d-glucopyranosyl (α-d-Glcp), β-d-glucopyranosyl (β-d-Glcp), and β-d-galactofuranosyl (β-d-Galf) connected by (1→3) linkages; branching was through (1→6) linkage in F3. A possible structure of EPS in F2 and F3 was proposed.

Abstract
In order to improve the hydrophilicity and immune activity of the polysaccharide from Dendrobium nobile Lindl., non-thermal plasma was used to treat the polysaccharide. It was found that the hydrophilicity of the polysaccharide plasma-treated was significantly enhanced. Infrared spectra showed that the content of OH in the molecule increased significantly, and the monosaccharide ring changed from β-pyran sugar to β-furan sugar. The detection of SEM, AFM and TEM showed that the degree of cross-linking of surface molecules increased, and the arrangement of the polysaccharide was more compact and orderly. In vitro cell tests showed that the polysaccharide plasma-treated significantly improve the phagocytosis ability of RAW264.7, and promote the secretion of cytokines TNF-α, IL-6, IL-1. However, the cell proliferation test indicated that the polysaccharide did not increase the concentration of cytokines by promoting cell proliferation. RT-PCR showed that the polysaccharide plasma-treated could promote the expression of IL-1β at the transcriptional level. These results showed that non-thermal plasma treatment can effectively enhance the hydrophilicity of the polysaccharide and enhance its immune activity in vitro. Therefore, it can be inferred that the non-thermal plasma technology can be applied to the modification of active polysaccharides and will promote active polysaccharides to work better.

Abstract
Bacterial infection is the most common cause of sepsis. In this study, Phascolosoma esculenta oligosaccharides (PEOs) were prepared to evaluate their resistance against E. coli-induced sepsis. HPLC-MS and FT-IR indicated that PEOs were composed of d-glucosyl, d-galactosyl, with small amount of d-mannosyl, d-arabinosyl and residues with α- and β-type linkage. Different dosage administrations of PEOs for 30 days significantly improved ICR mice survival rate and bacterial clearance ability (P < 0.01) after as E. coli injection. Moreover, PEOs significantly reduced the secretion of IL-1β and TNF-α and enhanced that of IL-10 in sepsis mice, enhanced the antioxidant enzyme activities and total antioxidant capacity, decreased MDA level in the serum, and upregulated mRNA expression of Nrf2 (P < 0.01). All these results indicate that PEOs could improve the resistance of ICR mice against E. coli-induced sepsis that attributed to anti-inflammatory and anti-oxidative stress.

Abstract
Lactic acid bacteria are fully recognized for their industrial applications among which the production and release of exopolysaccharides. In the present investigation, we screened fifteen Lactobacilli in order to find ropy strains, quantify exopolysaccharides and detect proteins specifically associated with the ropy-exopolysaccharide production. The highest ropy-exopolysaccharide producer (L. helveticus 6E8), was grown in stimulating and basal condition (10% and 2% lactose) and subjected to comparative proteomic analysis. The levels of 4 proteins were found significantly increased in the membrane fraction under stimulating conditions: a specific exopolysaccharide biosynthetic protein, a stress-induced protein, a protein involved in secretion and an ATP-synthase subunit. Conversely, several enzymes involved in anabolism and protein synthesis were decreased. These results suggest a general shift from growth to exopolysaccharide-mediated protection from the hyperosmotic environment. Due to the great interest in exopolysaccharides with novel features, the identification of these proteins could have implications for future improvements of industrial strains.

Abstract
Background: Oligosaccharides are composed of a variable number of monosaccharide units and very important in the biologically diverse of biological systems. Materials and Methods: Crude water-soluble oligosaccharide was extracted from the fruiting bodies with water and then successively purified by DEAE–cellulose 52 and Sephadex G-100 column chromatography, yielding one major oligosaccharides fractions: LES-A. Structural features of Lactarius deliciosus (L. ex Fr.) Gray oligosaccharide (LDGO-A) were investigated by a combination of monosaccharide component analysis by thin layer chromatography, infrared spectra, nuclear magnetic resonance spectroscopy, scanning electron microscopy, and high-performance gel permeation chromatography analysis. Result: The results indicated that LDGO-A was composed of D-glucose and D-xylose, and the average molecular sizes was approximately 945 Da. The anti-tumor activity of LDGO-A was evaluated in vivo. The inhibitory rate in mice treated with 40 mg/kg LDGO-A can reach 40.02%, being the highest in the three doses, which may be comparable to mannatide. Histology of immune organs shows that the tissues arranged more regular and firmer, but the tumor tissue arranged looser in LDGO-A group than those in the control group. Meanwhile, there is no obvious damage to other organs, such as heart. The anti-tumor activity of the LDGO-A was usually believed to be a consequence of the stimulation of the cell-mediated immune response because it can significantly promote the lymphocyte and macrophage cells in the dose range of 100–400 μg/mL in vitro. LDGO-A also effected the expression of some housekeeping genes mRNA in S180 tumor. Conclusion: Accordingly, the LDGO-A might serve as an effective healthcare food and source of natural anti-tumor compounds.

Abstract
A novel heteropolysaccharide from the fruiting bodies of Gomphus clavatus Gray was isolated through Sephadex G-200 and DEAE-cellulose columns. The Gomphus clavatus Gray polysaccharide (GCG-1) was mainly composed of β-D-glucosepyranose (β-D-Glu) and α-D-galactopyranose (α-D-Gal) in a ratio of 3:2 and had a molecular weight of ~50,000 Da. The structure of GCG-1 was investigated by a combination of total hydrolysis, gas chromatography-mass spectrometry, methylation analysis, nuclear magnetic resonance spectroscopy and infrared spectra. The results indicated that GCG-1 had a backbone of (1 → 4)-β-D-glucosepyranose residues with branches at O-6 and the branches consisted of two with (1 → 3)-α-D-galactopyranose residue. Antioxidation test in vitro showed that it possessed strong free radical scavenging activity, which may be comparable to vitamin C and butylated hydroxytoluene. GCG-1 also induced the apoptosis of HepG-2 cells and affected the mRNA expression of various housekeeping genes in the HepG-2 cells. The results indicated that Gomphus clavatus Gray may be an ideal sources for antioxidant and anticancer agents.

Abstract
A polysaccharide DOTP-80 from Dioscorea opposita Thunb was obtained by using the method of acid water-extraction and ethanol-precipitation. After being purified by chromatography, the structure characteristics of DOTP-80 were established. Based on the calibration curve obtained with standard dextrans, the molecular weight of the polysaccharide fraction DOTP-80 was calculated to be 123 kDa. The results of Infrared spectrum (FT-IR) indicated that the polysaccharide contained the α-configuration of sugar units. GC-MS analysis revealed that DOTP-80 was mainly composed of mannose and glucose. Alloxan-induced diabetic rats and mice models were developed to evaluate the in vivo hypoglycemic activity of the polysaccharide. The results indicated that a high dose DOTP-80 (400 mg/kg) had strong hypoglycemic activity. Moreover, DOTP-80 could increase the level of antioxidant enzymes (SOD) activity in alloxan-induced diabetic mice and stimulate an increase in glucose disposal in diabetic rats. Therefore, the polysaccharide DOTP-80 should be evaluated as a candidate for future studies on diabetes mellitus.

Abstract
A water-soluble polysaccharide from Sarcodia ceylonensis was obtained by using the method of water-extraction and ethanol-precipitation. The polysaccharide was further purified by chromatography on AB-8 and ADS-7 columns, yielding a pure polysaccharide termed SCP-60. The molecular weight (Mw) of SCP-60 was calculated to be 50.0 kDa, based on the calibration curve obtained with a series of Dextran T standards. The results of FT-IR indicated that the polysaccharide contains the α-configuration of sugar units. GC-MS analysis revealed that SCP-60 was mainly composed of galactose and glucose. NMR spectroscopy revealed SCP-60 had the backbone consisting of → 6)-α-Manp-(1 →, α-D-Glcp-(1 →, → 6)-α-D-Glcp-(1 → and → 6)-α-Galp-(1 →. In order to evaluate the antitumor activity in vivo of the polysaccharide, a sarcoma 180 model was used. The results showed SCP-60 had strong antitumor ability, meanwhile, SCP-60 at a high dose (100 mg/kg) could significantly increase the thymic and splenic indices of S180 mice, and strongly promote the secretion of IL-2, TNF-α and IFN-γ, increase the SOD activities and reduce the concentrations of MDA in blood. Therefore the polysaccharide SCP-60 should be explored as a novel potential antitumor drug.

Abstract
In this study, we purified and characterized a polysaccharide (SMP-W1) from Salvia miltiorrhiza and investigated its anticancer and immunoregulatory potential in vitro and in vivo. The monosaccharide composition, protein content, uronic acid content, total carbohydrate content, viscosity and molecular weight of SMP-W1 were analyzed. In vitro, SMP-W1 had an antiproliferative effect on hepatocellular carcinoma H22 cells, especially at the high concentration of 400 μg/ml. Simultaneously the polysaccharide SMP-W1 significantly inhibited tumor growth and increased serum superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px) activities in rats, as well as the secretion of TNF-α. In addition, the body weight, spleen index and thymus index in tumor-bearing mice were significantly improved by SMP-W1 treatment. Taken together, these results indicated that SMP-W1 possessed strong in vivo and in vitro anti-tumor activity and improves the immune response in tumor-bearing mice. Therefore, it could be developed as an anti-tumor agent with immunomodulatory activity.

Abstract
A water-soluble polysaccharide (BEBP) was extracted from Boletus edulis Bull using hot water extraction followed by ethanol precipitation. The polysaccharide BEBP was further purified by chromatography on a DEAE-cellulose column, giving three major polysaccharide fractions termed BEBP-1, BEBP-2 and BEBP-3. In the next experiment, the average molecular weight (Mw), IR and monosaccharide compositional analysis of the three polysaccharide fractions were determined. The evaluation of antioxidant activities both in vitro and in vivo suggested that BEBP-3 had good potential antioxidant activity, and should be explored as a novel potential antioxidant.

Abstract
Crude water-soluble Chinese truffle Tuber indicum polysaccharide (TIP) was extracted from the fruiting bodies with water and then successively purified by DEAE-cellulose 52 and Sephadex G-100 column chromatography, yielding two major polysaccharide fractions: TIP1-1 and TIP2-1. High-performance gel permeation chromatography analysis showed that the average molecular sizes of TIP1-1 and TIP2-1 were approximately 1.75×10(4) Da and 5.73×10(3) Da, respectively. Monosaccharide component analysis by gas chromatography indicated that TIP1-1 was composed of mannose, glucose, galactose, and rhamannose in the respective molar ratio of 3.93:1.24:0.75:1.26 and that TIP2-1 contained mannose, glucose, and arabinose in the respective molar ratio of 5.27:1.44:0.43. The antioxidant activity analyses revealed that TIP1-1 and TIP2-1 possessed considerable antioxidant activity. Compared with TIP1-1, which has a higher molecular weight and contains no uronic acid, TIP2-1 exhibited a protective effect on PC12 cells injured by H(2)O(2) and a higher scavenging activity against free radicals. The relative effects of the lower molecular size, the presence of uronic acid, and the antioxidant activity of TIP2-1 appear to be significant. Accordingly, the Chinese truffle T. indicum might serve as an effective antioxidative healthcare food and source of natural antioxidants.

Abstract
A novel structure of exopolysaccharide from the lactic acid bacteria (LAB) Lactobacillus rhamnosus KL37B, from the human intestinal flora, is described. During the structural investigation of the exopolysaccharide it was found that the repeating unit is a nonasaccharide, which is the largest repeating unit found in LAB exopolysaccharides to date. The polysaccharide material was prepared by TCA extraction of a bacterial cell mass, purified by anion-exchange and gel permeation chromatography and characterized using chemical and enzymatic methods. On the basis of monosaccharide and methylation analysis and also 1D and 2D (1)H and (13)C NMR spectroscopy the exopolysaccharide was shown to be composed of the following nonasaccharide repeating unit: The physicochemical cell surface study and adhesive properties indicated distinct surface properties of Lactobacillus rhamnosus strain KL37B with high adhesive abilities to Caco-2 cells, hydrophobicity and slime production, in comparison to other Lactobacillus strains used as controls.

Abstract
Sulphated galactan (SFA) containing alpha (α), iota (í) and pyruvated α-carrageenans (17.6:18.8:25.3 mol %) was extracted and characterized from Sarconema filiforme of Indian waters. The SFA and its alkali modified derivative (SFAM) were composed of D-galactose, 3, 6-anhydro-D-galactose, 6- O-methylated-D-galactose (64.5:23.0:9.8 and 59.6:29.8:7.6 mol %) respectively. The linkage analysis, physicochemical analysis, infra red and 13C nuclear magnetic resonance spectra of SFA along with linkage analysis of the desulphated derivative (SFD) of SFA, reveals that it was a hybrid/combination of α/í carrageenan as well as 3-linked 4′,6 ‘-O-(1-carboxyethylidene)-galactose (pyruvated α carrageenan) and 6 -O-methylated α-carrageenan. The flow behavior of SFA obtained from rheological measurements suggested strong network formation in presence of 1% aqueous KCl and CaCl2 solutions.

Abstract
In this study, the complex kappa-ca3000+CP combined collagen peptide with kappa-carrageenan oligosaccharide was tested for its ability to moderate UV-induced damage and investigated for its protective mechanism against UV radiation. Human keratinocytes (HaCaT) and mouse embryonic fibroblasts (MEF) were used to monitor the effects of kappa-ca3000+CP on cell viability, apoptosis, level of collagen I and MMP-1, MAPKs activation and intracellular ROS production after UV-irradiation. The results indicated that application of the kappa-ca3000+CP (100 microg/ml) could significantly attenuate UV-induced HaCaT and MEF death, as well as inhibit the UV-induced apoptosis of HaCaT cells. The decreased collagen I synthesis and the increased MMP-1 expression of MEF by UV radiation were almost restored back to normal level after treatment with kappa-ca3000+CP. Moreover, kappa-ca3000+CP could significantly suppress UV-induced MAPKs activation and intracellular ROS production. Taken together, these results showed that antioxidant property of kappa-ca3000+CP can effectively attenuate UV-caused cell damage and skin photoaging by suppressing cell apoptosis and expression of MMP-1 through the MAPKs signaling pathways. Thus, kappa-ca3000+CP has potential antiaging effects and prominent protective effects on UV-induced skin cell damages, which might be used in pharmaceutical and cosmetic industries.

Abstract
The neutral exopolysaccharide produced by Lactobacillus delbrueckii ssp. bulgaricus LBB.B26 in skimmed milk was found to be composed of d-glucose and d-galactose in a molar ratio of 2:3. Linkage analysis and 1D/2D NMR ((1)H and (13)C) studies performed on the native polysaccharide, and on an oligosaccharide obtained from a partial acid hydrolysate of the native polysaccharide, showed the polysaccharide to consist of branched pentasaccharide repeating units with the following structure.

Effective cellulose production by a coculture of Gluconacetobacter xylinus and Lactobacillus mali. Appl Microbiol Biotechnol 2006; 73:915-21.

Abstract
A microbial colony that contained a marked amount of cellulose was isolated from vineyard soil. The colony was formed by the associated growth of two bacterial strains: a cellulose-producing acetic acid bacterium (st-60-12) and a lactic acid bacterium (st-20). The 16S rDNA-based taxonomy indicated that st-60-12 belonged to Gluconacetobacter xylinus and st-20 was closely related to Lactobacillus mali. Cocultivation of the two organisms in corn steep liquor/sucrose liquid medium resulted in a threefold higher cellulose yield when compared to the st-60-12 monoculture. A similar enhancement was observed in a coculture with various L. mali strains but not with other Lactobacillus spp. The enhancement of cellulose production was most remarkable when sucrose was supplied as the substrate. L. mali mutants for exocellular polysaccharide (EPS) production were defective in promoting cellulose production, but the addition of EPS to the monoculture of st-60-12 did not affect cellulose productivity. Scanning electron microscopic observation of the coculture revealed frequent association between the st-60-12 and L. mali cells. These results indicate that cell-cell interaction assisted by the EPS-producing L. mali promotes cellulose production in st-60-12.

Carbohydr Res 2006; 341:634-8. [PMID: 16442509 DOI: 10.1016/j.carres.2006.01.004] [Citation(s) in RCA: 125] [Impact Index Per Article: 6.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2005] [Revised: 12/17/2005] [Accepted: 01/05/2006] [Indexed: 11/18/2022]
Abstract
A large number of polysaccharides are present in the pericarp tissues of harvested litchi fruits. A DEAE Sepharose fast-flow anion-exchange column and a Sephadex G-50 gel-permeation column were used to isolate and purify the major polysaccharides from litchi fruit pericarp tissues. Antioxidant activities of these major polysaccharide components were also evaluated. An aqueous extract of the polysaccharides from litchi fruit pericarp tissues was chromatographed on a DEAE anion-exchange column to yield two fractions. The largest amount of the polysaccharide fraction was subjected to further purification by gel filtration on Sephadex G-50. The purified product was a neutral polysaccharide, with a molecular weight of 14 kDa, comprised mainly of 65.6% mannose, 33.0% galactose and 1.4% arabinose. Analysis by Smith degradation indicated that there were 8.7% of (1-->2)-glycosidic linkages, 83.3% of (1-->3)-glycosidic linkages and 8.0% of (1-->6)-glycosidic linkages in the polysaccharide. Furthermore, different polysaccharide fractions extracted and purified from litchi fruit pericarp tissues exhibited strong antioxidant activities. Among these fractions, the purified polysaccharide had the highest antioxidant activity and should be explored as a novel potential antioxidant.
