Abstract

A fucoidan-utilizing marine bacterium, Fucophilus fucoidanolyticus, was cultivated in medium containing fucoidan from Cladosiphon okamuranus. The C. okamuranus fucoidan was digested into oligosaccharides with the intracellular enzymes of F. fucoidanolyticus, and their structures were determined by nuclear magnetic resonance analyses. Some of their structures are represented by one general structural formula, (-3 L-Fuc palpha1-3 L-Fuc p(4- O-sulfate)alpha1-3 L-Fuc p(4- O-sulfate)alpha1-3( D-Glc pUAalpha1-2) L-Fuc palpha1)(m)-3 L-Fuc palpha1-3 L-Fuc p(4- O-sulfate)alpha1-3 L-Fuc p(4- O-sulfate) alpha1-3 L-Fuc p ( m = 0, 1, 2, or 3). We concluded that all oligosaccharides obtained were derived from a sulfated-fucose-containing polysaccharide of C. okamuranus, which has a repeating unit of (-3 L-Fuc palpha1-3 L-Fuc p(4- O-sulfate)alpha1-3 L-Fuc p(4- O-sulfate)alpha1-3( D-Glc pUAalpha1-2) L-Fuc palpha1-).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
