ABSTRACT
For the first time, properties and structural peculiarities of exopolysaccharides produced by phototrophic bacteria Rhodobacter sphaeroides isolated from hydrocarbonate mineral waters in Armenia with a degree of mineralization in limits of 3.5-5.0g/l, pH 7.2 have been studied. It is noteworthy that despite membership of the isolated strains in one and the same genus, these strains are significantly different by the nature of the produced exooligosaccharide. The studies implemented show that phototrophic bacteria are able to synthesize exopolysaccharides with different compositions and structures: cyclic and linear, depending on the cultivation conditions.
