Abstract: A method for degrading and/or bioremediating waste wood containing pentachlorephenol (penta) using a fungal inoculum is disclosed. The fungal inoculum comprises of at least one penta-tolerant fungi, a lignocellulosic substrate and a nutrient supplement. The fungal inoculum is applied to the waste wood and maintained in an aerated and hydrated environment having temperature conditions sufficient to allow the inoculum to grow and metabolize the pentachlorophenol. The inoculum and the waste wood are combined until an end product is achieved that is at least partially remediated or of a reduced volume.
