[Decolorization conditions for reactive brilliant blue KN-R by three fungi].
Seventeen strains with wideranging decolorization ability were screened from contaminated soil and were applied on the decoloring of dye wastewater. Three strains were selected due to their high decolorization capacity on azo dyes, anthraquinone dyes and triphenylmethane dyes. The three strains were named as Strain I, Strain II, Strain III. This three superior strains were identified as penicillium link (Strain I & strain II) and Cephalosporium corda (strain III). Using aqueous samples, the influences of several factors on decolorization were reported, such as pH, carbon source, temperature and so on. And then applying of these strains for treatment of actual wastewater have also been done. The results showed that the optimal pH, temperature and carbon source were 5-9, 18-37 degrees C and 0.5% respectively, under those conditions the decolorization removal rate was 70%. And these fungi have a good prospect for the treatment of dye wastewater.
