Effect of salted whey medium after optimization as culture medium on the chemical composition and Functional properties of exopolysaccharide produced by Halomonas eurihalina F2-7and Xanthomonas campestrispv. campestris was studied . All polymers (EPSs) extracted from optimized reconstituted salted whey medium (ORSW) had lower contents of carbohydrates (29.34– 23.72%) but, were highly proteins (8.79–12.15%) than synthetic media-EPSs. Considerable quantities of uronic acid and sulfates were detected in Halomonas-EPSs (4.7 - 3.8% and 8.33–17.11%, respectively). All polymers produced viscous solutions with pseudoplastic behavior and emulsified sunflower oil. Aqueous solutions (1%, w/v) of Xanthomonas-EPS, especially, collected from synthetic medium(MM) were highly viscous (97.7cPs) at pH 7 and also were of the highest viscosity (122.4cPs), when heated at 70ºC. The polymers extracted from ORSW medium, especially, Halomonas-EPS had the highest emulsifying activity at pH 3 and 7(80 and 71.25 – E96 respectively) .The most interesting EPSs, was Halomonas-EPS which extracted from ORSW medium, where produced viscous solutions, their viscosity increased from 15.4 to 82.7cPs at pH 3 and also produced stable emulsion (80-E240) till 240 hr at the same pH. These properties makes it potentially useful for various industrial applications.
