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).
