Title
(EN) FUCOSE-CONTAINING BACTERIAL BIOPOLYMER
(FR) BIOPOLYMÈRE BACTÉRIEN CONTENANT DU FUCOSE
Abstract
(EN)
The present invention 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 invention 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 present invention 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).
(FR)
La présente invention porte sur un biopolymère microbien comprenant du fucose dans sa composition. Ce biopolymère est constitué d'un polysaccharide comprenant du fucose, qui représente au moins 10 % de sa composition. Ce polysaccharide contenant du fucose contient également des composants qui ne sont pas des sucres, à savoir des substituants de type groupes acyles. Cette invention porte également sur le procédé pour la production du biopolymère, qui est obtenu par culture de la bactérie Enterobacter A47 (DSM 23139), à l'aide de glycérol ou de mélanges riches en glycérol en tant que sources de carbone. Le biopolymère contenant du fucose de la présente invention peut être utilisé dans plusieurs applications industrielles (par exemple les industries pharmaceutiques, cosmétiques et agroalimentaires) et dans le traitement de déchets industriels (par exemple la récupération d'huile et de métaux).
