Fifteen Cyanothece strains isolated from saline environments have been characterized with regard to exopolysaccharide (EPS) production. The polymers contained six to eight monosaccharides, with one or two acidic sugars. In some EPS samples, the additional presence of acetyl, pyruvyl, and/or sulfate groups was also detected.
