This study investigated the bioremediation of wood treated with copper–chromium– arsenic (CCA-C), alkaline copper quat (ACQ), and micronized copper quat (MCQ) using two Phanerochaete chrysosporium fungal strains. Wood flour samples were incubated in fungal liquid cultures over 1 to 10 days. Fungal treatments removed substantially more copper than distilled water controls across all preservative types. Lower preservative loadings yielded copper extraction rates exceeding 90–95% for ACQ and MCQ, whereas higher loadings reduced efficiency. The P. chrysosporium Me strain demonstrated superior performance during later remediation stages. These findings confirm that P. chrysosporium effectively mobilizes copper from soluble and micronized formulations, offering a viable strategy for detoxifying waste wood and enabling resource recovery.
