|Abstract: ||Enterobacter strain A47 (DSM 23139) was found to produce a fucose-containing exopolysaccharide (EPS).
The EPS is composed of fucose, galactose, glucose, pyruvate, succinate and acetate in the molar ratios
1.6:1.3:1.1:1.2:0.7:1.5. It is a high molecular weight (5.8×106) homogeneous biopolymer, as indicated
by the low polydispersity value (1.3). The steady shear flow properties of the EPS aqueous solutions are
similar to guar gum and fucogel, and its viscoelastic properties indicate the formation of viscous aqueous
solutions with entangled polymer chains. Additionally, the EPS has demonstrated good flocculating and
emulsion stabilizing capacities, comparable to some commercially available products. These functional
propertiesmakethe fucose-containing EPS a good alternative tomanysynthetic polymers, as well as other
natural polysaccharides, in several applications in the food, pharmaceutical, cosmetic, textile, paper and
