ABSTRACT:
A method of making a wood pulp is disclosed. The method includes chipping wood into wood chips and then inoculating the wood chips with an inoculum of a white rot fungi and a nutrient adjuvant selected from the group consisting of corn steep liquor, molasses and yeast extract. The wood chips are introduced into a bioreactor and incubated. The incubated wood chips are then pulped. A method of pretreating wood including chipping the wood into wood chips and inoculating the wood chips with an inoculant of the white rot fungi and a nutrient adjuvant selected from the group consisting of corn steep liquor, molasses and yeast extract is also disclosed. A method for producing paper from the treated wood chips is also disclosed. The addition of the nutrient adjuvant dramatically reduces the amount of fungal inoculant needed (by multiple orders of magnitude), to achieve similar results.
