Disclosed herein is a sphingan oligosaccharide composition, its uses, and a process for preparing the same.

The present invention discloses a matrix comprising a modified polysaccharide consisting of repeating disaccharide units whereby in at least 11% of the disaccharide units one primary alcohol group is oxidized into a carboxylic acid group.

Described herein are methods of producing prebiotic compositions that are made up of oligosaccharide compositions, as well as methods of using such prebiotic compositions in nutritional compositions and methods of producing such oligosaccharide and nutritional compositions.

Aspects of the disclosure relate to oligosaccharide compositions and methods of making the same. Also provided are methods of using oligosaccharide compositions as microbiome metabolic therapies for reducing ammonia levels and for the treatment of related diseases.

Disclosed herein is an ingestible composition comprising a sphingan and its use as a prebiotic.

The present invention provides capsular polysaccharides from Streptococcus pneumoniae serotypes identified using NMR. The present invention further provides polysaccharide-protein conjugates in which capsular polysaccharides from one or more of these serotypes are conjugated to a carrier protein such as CRM197. Polysaccharide-protein conjugates from one or more of these serotypes may be included in multivalent pneumococcal conjugate vaccines having polysaccharides from multiple additional Streptococcus pneumoniae serotypes.

A fabrication method for a water-absorbent filter includes obtaining a homogenized tragacanth suspension by dissolving tragacanth in a solvent, where the solvent may include distilled water, ethyl acetate, acetic acid, and formic acid, obtaining a support layer by coating a stainless steel mesh with a thin layer of a hydrophobic polymer, coating a stainless steel mesh with the thin layer of the hydrophobic polymer comprising electrospinning a hydrophobic polymer solution onto the stainless steel mesh, forming a tragacanth nanofibrous web on the support layer by electrospinning the homogenized tragacanth suspension onto the support layer, and cross-linking the tragacanth nanofibrous web by exposing the tragacanth nanofibrous web to a saturated vapor of a cross-linking agent.

The present invention relates to process for preparing partially deacylated gellan gum, the process comprising subjecting native or high acyl gellan gum to treatment with an esterase capable of partially deacylating gellan gum.
