Abstract
A method for degrading and/or bioremediating waste wood containing ammoniacal copper quat (ACQ) using a fungal inoculum is disclosed. The fungal inoculum comprises of at least one ACQ-tolerant fungus 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 ACQ. 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.
Claims15
A method for bioremediating wood containing ammoniacal copper quat (ACQ) comprising the steps of:
- inoculating wood containing ACQ with a fungal inoculum comprising at least one ACQ-tolerant fungus, at least one lignocellulosic substrate and at least one nutrient supplement, the lignocellulosic substrate and the nutrient supplement in an amount sufficient to produce a biomass of the fungal inoculum sufficient to at least partially remediate the ACQ;
- and
- aerating and hydrating the inoculated wood for a time and under conditions sufficient to allow the fungal inoculum to remediate the ACQ.
A method for degrading wood containing ammoniacal copper quat (ACQ) comprising the steps of:
- inoculating wood containing ACQ with a fungal inoculum comprising at least one ACQ-tolerant fungus, at least one lignocellulosic substrate and at least one nutrient supplement, the lignocellulosic substrate and nutrient supplement in an amount sufficient to produce a biomass of the fungal inoculum sufficient to degrade the wood;
- and
- aerating and hydrating the inoculated wood for a time and under conditions sufficient to allow the fungal inoculum to degrade the wood to reach a degradation product.
