The extracellular polymeric substance produced by dry soil isolate Pseudomonas putida CMGl447mp was characterized for hydrophilic and halophilic activities. CMG1447mp was found to produce a similar polymer from either fructose or glucose or sucrose and polymer from each carbon source was an anionic heteropolysaccharide containing glucuronic acid, D- glucose with higher concentration, D-mannose and L-rhamnose. The polymer produced from different carbon sources was found to express high hydrophilic and halophilic activities in both hot and cold environments. Bacterial origin polymer was hygroscopic, heat stable and can function as water reservoir.
