Abstract

The wood-degrading fungus Trichophyton sp. LKY-7 (T. LKY-7) was immobilized in ca-alginate beads for laccase production and PCP bioremediation. The immobilized T. LKY-7 enabled the repeated use of this fungus for laccase production and produced high amount of laccase throughout 5 cycles incubation. As a laccase inducer. oak wood meal (Quercus variabilis) seemed to be effective laccase inducer for T. LKY-7, and the optimum addition amount was 1％ (W/W) in glucose-peptone medium. Bioremediation of pentachlorophenol by the immobilized T. LKY-7 reached an efficency of up to 90％ without toxic inhibition. The immobilized T. LKY-7 might thus be applicable for semicontinuous laccase production and bioremediation to serve inoculum for reactor system.
