摘要：

Hyphomonas MHS-3 is a biphasic, marine bacterium that synthesizes an exopolysaccharide (EPS) capsule, which has a role in attaching the adherent, prosthecate developmental stages to solid substrata. To correlate structure with function, we characterized this integral EPS. It has a relatively homogeneous molecular weight of approximately 60 000 daltons, is acidic, and putatively contains large concentrations of N-acetylgalactosamine (GaINAc). The theoretical identity of the anionic component of the polymer, and the similarities between Hyphomonas MHS-3 EPS and other adhesive marine/aquatic bacterial EPS are discussed.
