The invention relates to an exopolysaccharide (EPS), compositions comprising EPS and methods of use, including for treating and preventing disorders, such as inflammatory disorders.

The present disclosure provides methods of improving the resolution of labeled glycans in capillary electrophoresis techniques using a gel as a sieving matrix, by incorporating polyamines in the gel.

A composition of chemically purified soluble mannans from legumes' seeds (e.g. Ceratonia siliqua, Csalpinia spinosa Trigonelle foenum-graecum, and Cyamopsis tetragonolobus) and their use in the assembly of palatable dietary supplements is disclosed herein. The fractionation process provides high-quality physiologically soluble, chemically modified and purified homogeneous size polysaccharide fibers, devoid of natural impurities, for example proteins, alkaloids, glycoalkaloids, and/or environmental impurities including heavy metals, agricultural residues and microbial toxins. This process provides hypoallergenic dietary fibers devoid of any potential allergens, cytotoxins, and gastrointestinal toxins. A sequential process for assembly of the soluble fibers with plurality of molecular weights to create a time controlled dissolution of the functional high and low molecular weight fibers for improving solubility and palatability with improved dietary performance in the oral and gastro-intestinal system is also disclosed herein.

Provided is a method to increase the growth of a plant by coating a seed of said plant with a composition comprising at least one of various cationic compounds; notably permitting to develop its biomass and reach its maturity. Provided also is a seed coating composition used in such a method.

The present invention describes a method for preparing a polymannan extract from freeze-dried aloe powder. The polymannan extract of the present invention is further used to formulate a sterile injectable formulation for the treatment of one or more cancers, leukemias and lymphomas, prostate cancer, breast cancer, and colon cancer, immune diseases, particularly immune related neoplasms, acquired immune deficiency syndrome, and hepatitis C.

An anti-accretion drilling fluid additive comprising at least one of a hydrophobically modified natural polysaccharide and hydrophobically modified and chemically derivatized polysaccharide; and whereby said additive acts as a bitumen encapsulant to provide a barrier against bitumen accretion during drilling in steam assisted gravity drainage (SAG) operations.

Methods or preparing para-xylene from biomass by carrying out a Diels-Alder cycloaddition at controlled temperatures and activity ratios. Methods of preparing bio-terephthalic acid and bio-poly(ethylene terephthalate (bio-PET) are also disclosed, as well as products formed from bio-PET.

Chlorella mannogalactan (CM) or a sulfated Chlorella mannogalactan (SCM) compound and application of the SCM compound are disclosed. The CM is obtained by extracting total polysaccharides from Chlorella dry powder before performing separation and purification. The SCM compound is obtained by sulfation modification of the CM. The CM and the SCM compound both consist of mannose, 3-O-methyl-mannose, and galactose. The SCM compound and an excipient thereof form a pharmaceutical composition that can be used as a lyophilized powder injection or an aqueous solution for injection for prevention and/or treatment of thrombotic cardiovascular diseases. The CM or the SCM compound and the application of the SCM compound are adopted. The SCM has good water solubility and strong anticoagulant activity, which can be comparable to enoxaparin sodium.

A composition contains a silylated polysaccharide, where the silylated polysaccharide is characterized by: (a) having linked fructose, galactose, anhydrogalactose, or glucose saccharide units provided that glycosidic linkages of glucose are alpha linkages and that the silylated polysaccharide is other than a silylated starch; and (b) on average 1 to 100 mole-percent of the hydroxyl groups on the polysaccharide have been silylated with a silyl group having the structure SiR.sub.3 linked to the polysaccharide through a COSi bond where each R is independently selected from hydrocarbyl radicals having from one to 12 carbon atoms, provided that on average at least one R per polysaccharide has a terminally unsaturated carbon-carbon double bond.

The present invention relates to new methods for crosslinking a polysaccharide with a bifunctional poly(ethylene glycol). The invention further includes the polymer hydrogels which can be produced using these methods, compositions comprising the polymer hydrogels and methods of use thereof.
