This patent describes the polyvalent metal ion complex of a fungal polysaccharide wherein the polyvalent metal ion is a member selected from the group consisting of titanium ion and chromium ion. The polysaccharide is a scleroglucan having a linear chain of anhydroglucose units linked beta 1,3 with 30-35% of the linear chain units bearing single appended anhydroglucose units linked beta 1,6. The complex is prepared by forming a water solution of the polysaccharide and adding thereto a water soluble reducing agent and a water soluble member selected from the group consisting of titanium compounds and chromium dichloride to form the complex.
