Biotechnology, 2002, 1(1), 28-33.


Present study shows the complexity of determining the chemical composition of three exopolysaccharides obtained from bacteria associated with plant roots grown under salt stress conditions. Physicochemical analysis indicated that the exopolysaccharides were varying in their chemical composition. Presence of the sugar shows that these were hetero/homo polysaccharides. IR analysis of the crude extracts for the presence of functional groups indicated a need for more purification of exopolysaccharides. Moreover the IR analysis along with histochemical studies showed the presence of hydroxyl, carboxyl and nitro groups. The physicochemical characteristics of the exopolysaccharides showed that the exopolysaccharides would be used in industrial applications. However, a thorough investigation is needed to determine their industrial application.
