Abstract: Flat sheet membrane ultrafiltration cup with membrane molecular weight of 70,000 was used to concentrate PS-9415 fermentation broth.Increasing the operation pressure could improve the permeation flux,So did better agitation and lower initial concentration.The concentration of exopolysaccharides broth (0.5%) could be increased 2 fold under the condition of 0.15MPa and room temperature.
Key words: flat sheet membrane utrafiltration, exopolysaccharides PS-9415
