Abstract: The presently disclosed subject matter concerns a microbial biopolymer comprising fucose in its composition. This biopolymer consists of a polysaccharide comprising fucose, which represents at least 10% of its composition. This fucose-containing polysaccharide also contains non-sugar components, namely, acyl group substituents. This disclosed subject matter also concerns the process for the production of the biopolymer, which is obtained cultivation of the bacterium Enterobacter A47 (DSM 23139), using glycerol or glycerol-rich mixtures as carbon sources. The fucose-containing biopolymer of the presently disclosed subject matter may be used in several industrial applications (e.g. pharmaceutical, cosmetics and agro-food industries) and in the treatment of industrial wastes (e.g. oil and metal recovery).

Abstract: The present invention concerns a natural biocomposite powder prepared from the biomass of yeast Pichia pastoris, comprising chitin-glucan complex (CGC) and mannose-containing polysaccharides. In a second aspect, the invention concerns the method of preparation of the natural biocomposite powder.

Abstract: This invention concerns a biopolymer consisting of a polysaccharide composed of galactose (50-90%), glucose (1-25%), mannose (1-25%) and rhamnose (0.5-20%), which may additionally contain, in trace amounts, xylose, fucose, ribose, arabinose and/or fructose. The galactose-rich polymer also contains non-saccharide components, namely, acyl groups. This invention also concerns a process for the production of the galactose-rich polymer, by microbial fermentation using glycerol or glycerol-rich substrates as carbon source, and recovery of the polymer from the culture broth. From the process for the production of the galactose-rich polymer results the co-production of intracellular biopolymers, namely, polyhydroxyalkanoates.
