Abstract: Four Polystictus versicolor strains such as PVC0‚PVC1‚PVC2and PVC3were examined for their ability to decolorize refinery effluent‚which contains Melanoidin‚HADP’S and Caramel.The preparation ability of the four strains for mycelium polysaccarride was also studied.The results show that Polystictus versicolor has high decolorization ability on effluent‚and can produce mycelium PSK and extracellular PSK at the same time.Colorants will not cause the change of PSK structure‚and PVC0 is the best strain for decolorization and PSK preparation.

Key words: refinery effluent, Polystictus versicolor, decolorization, polysaccharide
