NOVELTY - Wood containing chromated copper arsenate is bioremediated or degraded by inoculating wood with a fungal inoculum comprising chromated copper arsenate-tolerant fungus, lignocellulosic substrate and/or nutrient supplement.    USE - The method is used for bioremediating or degrading wood containing CCA, for use in decks, docks and buildings or as utility poles and railroad ties.    ADVANTAGE - The CCA-tolerant fungi utilized does not require genetic alteration to grow in the presence CCA, thus introduction of the fungi into the environment provides no new, non-naturally occurring organisms. The preparation and use of the fungal inoculum is simple. The products obtained provide a quick and low cost food source for the fungus while added effect of stimulating rapid and extensive fungal growth as well as providing a readily storable and transportable solid matrix. The solid matrix of the fungal growth which is similar to that of the waste wood, thus the fungal strain can be readily adapted to the waste wood environment upon inoculation and does not require a period adjustment before degradation and bioremediation begins.    DETAILED DESCRIPTION - Bioremediation of degradation of wood containing chromated copper arsenate (CCA) involves:    (1) inoculating wood containing CCA with a fungal inoculum comprising CCA-tolerant fungus, lignocellulosic substrate and/or nutrient supplement; and    (2) aerating and hydrating the inoculated wood for a time to allow the fungal inoculum to remediate or degrade the wood to reach a degradation product.    The lignocellulosic substrate and the nutrient supplement produce a biomass of the fungal inoculum to at least partially remediate the CCA or degrade the wood.    An INDEPENDENT CLAIM is also included for a method for preparing a fungal inoculum for degrading or bioremediating wood containing CCA comprising:    (1) combining a CCA-tolerant fungus with a matrix comprising lignocellulosic substrate, nutrient supplement and/or sterile water; and    (2) growing the CCA-tolerant fungus and matrix combination in dark, aerobic conditions at a relative humidity of 70% at 20-35 degrees C.
