Complexes of Cu-Polysaccharide of a Marine Red Microalga Produce Spikes with Antimicrobial Activity.

Metal-polysaccharides have recently raised significant interest due to their multifunctional bioactivities. The antimicrobial activity of a complex of CuO with the sulfated polysaccharide (PS) of the marine red microalga sp. was previously attributed to spikes formed on the complex surface (roughness).

Red Microalgal Sulfated Polysaccharide-CuO Complexes: Characterization and Bioactivity.

The anion-exchange capacity of the cell-wall sulfated polysaccharide of the red microalga sp. can be exploited for the complexation of metal ions (e.g.
