Production of Exopolysaccharide by An Indigenous Soil Isolate

An indigenous soil isolate identified as Pseudomonas aeruginosa produces exopolysaccharide. The organism is multiple antibiotic and multiple metal resistant. It shows resistance to ampicillin, chloramphenicol, kanamycin, copper, zinc, lead and nickel. Polysaccharide consists of glucose and unidentified pentose and its production is increased by the addition of sodium chloride. The isolate accumulates nickel from the medium.
