The induction and measurement of cytochrome P450 in white rot fungus Phanerochaete chrysosporium were studied in this work.The spectrophotometric results demonstrated that n-hexane was able to induce the fungal P450 to high level,which facilitated isolation and measurement of microsomal P450.The highest concentration of microsomal P450 could reach 140~160(pmol/mg) after 6-h-induction by addition of 2(μL/mL) hexane each hour,and the concentration of hexane and incubation time had significant effect on the in...
