NOVELTY - Method for bioremediating wood containing chromated pentachlorophenol comprises inoculating the wood with a fungal inoculum and aerating and hydrating the inoculated wood. The fungal inoculum comprises penta-tolerant fungus, lignocellulosic substrate, and nutrient supplement.    USE - The method is for bioremediating or degrading wood containing chromated pentachlorophenol (claimed).    ADVANTAGE - The inventive method provides product having reduced volume and/or capacity to be reused as a wood fiber resource. The penta-tolerant fungi used do not require genetic alteration to grow in the presence of pentachlorophenol, thus the introduction of the fungi into the environment provides no new, non-naturally occurring organisms. The use of fungal inoculum is simple and utilizes agricultural waste products and waste products from saw mills and urban chipping. These products provide quick and low cost food source for the fungus, while having the added effect of stimulating rapid and extensive fungal growth, and provides a storable and transportable solid matrix.    DETAILED DESCRIPTION - Method for the bioremediation of wood containing chromated pentachlorophenol (penta) comprises:    (a) inoculating the wood containing chromated pentachlorophenol with a fungal inoculum; and    (b) aerating and hydrating the inoculated wood to allow fungal inoculum to remediate the pentachlorophenol.    The fungal inoculum comprises penta-tolerant fungus, lignocellulosic substrate, and nutrient supplement. The substrate and the nutrient supplement produce a biomass of the fungal inoculum that partially remediates the pentachlorophenol.    INDEPENDENT CLAIMS are also included for:    (1) a method for preparing a fungal inoculum comprising combining a penta-tolerant fungus with a matrix comprising lignocellulosic substrate, nutrient supplement, sterile, and water, and growing the penta-tolerant fungus and matrix combination in dark, aerobic conditions, at 70 % relative humidity (RH) and 20-35 degrees C; and    (2) a method for degrading wood.
