Abstract

Phanerochaete chrysosporium is the white rot fungi which can degrade lignin of wood. The result of studying enzyme lignin peroxidase activity of the strain P.36201 of this fungi by oxidation veratryl alcohol to veratryl aldehyd shows that: the rate of veratryl aldehyde formation on liquid medium increases to the sixth day then decreases gradually. This is the suitable period to receive enzyme. On acisia sawdust, the enzyme which has the highest activity is received from 40% (NH4)2SO4 segment.
