Abstract
The present invention is directed to a Sphingomonas bacteria and a method of producing exopolysaccharides by culturing a Shingomonas bacteria in a fermentation broth for a time and temperature effective for providing a sphingan exopolysaccharide in a slime form.
Claims3
An isolated bacterium of a strain of Sphingomonas selected from the group consisting of ATCC PTA-3487, ATCC PTA-3486, ATCC PTA-3485, ATCC PTA-3488, and mutants or derivatives thereof capable of producing an exopolysaccharide in slime form, and mixtures thereof.
An isolated bacterium of a strain of Sphingomonas which produces an exopolysaccharide selected from the group consisting of gellan, welan, rhamsan, S-88, S-7, S-198, NW-11, S-657 in slime form when subjected to submerged fermentation.
