Microorganisms inhabiting saline environments can produce compounds unique in structure and properties. This ability recently prompted researchers to study the biotechnological potential of halophiles. This work aimed at screening the exopolysaccharideproducing halophilic and halotolerant microorganisms of two saline lakes, one in in Egypt and the other in Russia. For strain isolation and characterization, we used microbiological and physico-chemical methods, as well as light and transmission electron microscopy.
