Adsorption and degradation of azo-dye by Mold 7 under open system

The adsorption and degradation of azo dyes by mycelium pellets of Mold 7 were studied in open system,including the conditions such as the cultivation time of mycelia,dosage of carbon and nitrogen,dosage of mycelia,time of adsorption and degradation and reuse of mycelia.The results showed that the mycelia cultivated for 36 h could grow,adsorb and degrade dyes under the conditions of glucose 2.5 g/L,NaNO30.5 g/L,KH2PO4 1.0 g/L,MgSO4 0.5 g/L.The ultraviolet spectrum analysis and experimental observations of culture medium of the dyes after treatment with mycelium pellets of Mold 7 showed that the degradation rate and degradation effect of Acid Purple was better than those of Reactive Brilliant Red.In open system,the mycelia displays better growth vigor,balling ability,recyclability and antimicrobial ability.
