Patent

CA 2048047

The invention concerns a compound comprising a polysaccharide obtained through succinoglycan-based microbial fermentation and a natural polysaccharide or one of its derivatives; the mass ratio between the succinoglycan and the natural polysaccharide or one of its derivatives ranges from 5:95 to 95:5. The invention also concerns a process for producing this compound; more specifically, it is a process for precipitating dissipated particles in an aqueous medium, the concentration of the compound in the aqueous medium ranging from 0.001 and 0.5% in weight. The invention also concerns the use of such a compound for wastewater treatment.
