Extracellular and membrane polysaccharides of halophilic bacteria arouse the interest of researchers as promising biopolymers involved in adaptation and maintenance of normal physiology of microorganisms in saline environments that accompany many biotechnological processes. This work aimed at structural characteristic of surface glycopolymers of halophilic Gram-negative bacteria isolated from the salt samples of the lakes Qarun (Egypt) and Elton (Russia) – strains Chromohalobacter salexigens EG1QL3 and Halomonas ventosae RU5S2EL, respectively.
