The effects of Trichoderma spp. on wood degradation with Fomitopsis palustris and Trametes versicolor were examined. Japanese white birch (Betula platyphylla var. japonica) blocks were covered with four Trichoderma spp. immobilized on charcoalparticles (pH≒8), and exposed to the two basidiomycetes at 25 oC for 12 weeks to measure block mass losses. ANCT-05013 of Trichoderma spp. gave the strongest wood degradation inhibition. The decrease in mass losses without Trichoderma spp. was 51 - 80 %, while with the strain, it was only 3 - 6%.
