Decolorization of high concentrations of synthetic dyes by the white rot fungus Bjerkandera adusta strain CCBAS 232

摘要

Among thirty different basidiomycetes screened,Bjerkandera adusta strain CCBAS 232,Phanerochaete chrysosporium strain CCBAS 571 and Pleurotus ostreatus strain CCBAS 473 showed the best decolorization properties.B.adusta strain CCBAS 232 was able to decolorize a number of chemically different synthetic dyes(Orange G,Amaranth,Remazol Brilliant Blue R,Cu-phthalocyanine and Poly R-478)at relatively high concentrations of 2-4 g L~(-1)both on solid and in liquid medium.This strain also grew easily and produced biomass under these conditions.Unlike P.chrysosporium and P.ostreatus,B.adusta was able to efficiently decolorize all tested dyes.These properties and also a good ligni-nolytic enzyme production predetermine B.adusta strain CCBAS 232 for biotechnological applications.
