RESUMO
Four Polystictus Versicolor PVC0? PVC1? PVC2 ?PVC3 were examined for their decolorization ability to simulative refinery effluents and biodegradation ability to HADP'S, Melanoidin, Caramel The effect of effluent colorants on the yield of four Polystictus Versicolor biomass and mycelium polysaccarride(PSK) was also studied PVC0 showed the best decolorization ability and the high biomass; although the PSK content of PVC0 is less than PVC1, its yield of mycelium PSK is the highest Chosen PVC0 as the research strain The result showed that the rate of decolorization of PVC0 to 75% concentration real refinery effluents is 53% Which is less than to the simulative refinery effluent decolorization rate 71% Real refinery effluents and simulative refinery effluent has the same PVC0 biomass and PSK yield
