Production of non-native bacterial exopolysaccharide in a recombinant bacterial host

摘要

A new recombinant bacteria for the production of exopolysaccharides is disclosed as well as a method for making the recombinant bacteria and making an exopolysaccharide from the bacteria by submerged aerobic fermentation of the bacteria utilizing a sugar substrate. The exopolysaccharides obtained from the inventive bacteria exhibit improved, more desirable or different properties from the exopolysaccharide produced by the non-recombinant bacteria from which the recombinant bacteria was derived. In addition, the present invention provides a method of producing bacterial exopolysaccharides by fermentation from sugar substrates that the bacteria which the exopolysaccharides are native to cannot utilize.
