GALACTOSE-RICH POLYSACCHARIDE, PROCESS FOR THE PRODUCTION OFTHE POLYMER AND ITS APPLICATIONS

This invention concerns a biopolymer consisting of a polysaccharide compo sed of galactose (50-90%), glucose (1- 25%), mannose (1-25%) and rhamnose (0 .5-20%), which may additionally contain, in trace amounts, xylose, fucose, r ibose, arabinose and/or fructose. The galactose-rich polymer also contai...

Zusammenfassung:	This invention concerns a biopolymer consisting of a polysaccharide compo sed of galactose (50-90%), glucose (1- 25%), mannose (1-25%) and rhamnose (0 .5-20%), which may additionally contain, in trace amounts, xylose, fucose, r ibose, arabinose and/or fructose. The galactose-rich polymer also contains n on-saccharide components, namely, acyl groups. This invention also concerns a process for the production of the galactose-rich polymer, by microbial fer mentation using glycerol or glycerol-rich substrates as carbon source, and r ecovery of the polymer from the culture broth. From the process for the prod uction of the galactose-rich polymer results the co-production of intracellu lar biopolymers, namely, polyhydroxyalkanoates. This invention also concerns to the application of the galactose-rich polymer and the products of its pa rtial or complete degradation and/or derivatization, namely, galacto- oligos accharides, galactose, rhamnose and others, by physical, chemical and/or bio logical methods, in food, agricultural, textile and paper industries, pharma ceutical and cosmetic products, oil and metal recovery in mining industry, i ndustrial waste treatment and wastewater treatment, among others.
