Polysaccharides have a general formula of Cx(H2O)ywherexis usually a large number between 200 and 2500. Considering that the repeating units in the polymer backbone are often six-carbon monosaccharides, the general formula can also be represented as (C6H10O5)nwhere where 40<n<3000.. WHAT IS ...
Polysaccharides, which are the principal constituents of dietary fibre, show a wide spectrum of physical properties, reflecting the nature and extent of intermolecular association. At one extreme, the polymer chains may be packed together into ordered assemblies, such as cellulose fibrils, which are ...

The levels of Ca(2+) and Mg(2+) ions bound by whole Proteus cells were measured, as well as the chemical nature of isolated LPS polysaccharides, and the intensity of the in vitro crystallization process was compared in a synthetic urine. The results suggest that the sugar composition of ...
Genome-guided isolation of the hyperthermophilic aerobeFervidibacter saccharireveals conserved polysaccharide metabolism in theArmatimonadota Few aerobic hyperthermophilic microorganisms are known to degrade polysaccharides. Here, Nou et al. use genomic information to enrich and optical tweezers to isolate an ...
Pyrolysis data revealed chromatographic peaks related to polysaccharides-, proteins- and lignin-derived compounds. Both pyrolysis and TMAH thermochemolysis data show degradation of lignin structures during the growth period. Lignin alteration primarily involved a preferential degradation of syringyl units and...

Colonic bacteria, exemplified by Bacteroides thetaiotaomicron, play a key role in maintaining human health by harnessing large families of glycoside hydrolases (GHs) to exploit dietary polysaccharides and host glycans as nutrients. Such GH family expansion is exemplified by the 23 family GH92 glycosidase...
Although LPMO-type activity of X325 members was initially expected, we demonstrated that X325 members do not perform oxidative cleavage of polysaccharides, establishing that X325s are not LPMOs. Investigations of the biological role of X325 in the ectomycorrhizal fungus Laccaria bicolor revealed ...
