In this study, the nutritional and environmental conditions of a laccase produce strain, Pycnoporus sp. SYBC-L1, were investigated and optimiz ed though single factor experiments and orthogonal experiments. The optimum conditions described as follows: wheat bran cooking liquor 60 g/L, glucose 60 g/L, soybean powder 15 g/L and CuSO_·5H_2O 1.0 mmol/L, pH 3. 0, temperature 30 ℃, and culture volumn 50 mL/250 mL, respectively. With those optimum conditions, the laccase activity reached at 24. 95 U/mL after 13 days culture.
