Abstract
|
|
|
|
Veratryl alcohol which has been reported as an inducer for lignin peroxidase showed different effects on the enzyme biosynthesis in Phanerochaete chrysosporium depending on the addition time. Enzyme expression was optimally induced by adding veratryl alcohol when the carbon source began to be depleted. Hydrogen peroxide, to some extent, stimulated production of lignin peroxidase, but beyond a certain concentration, inactivated lignin peroxidase. Tween 80 induced the formation of small pellets, which were resistant to the deactivation by shear stress. Lignin peroxidase production was increased twice compared with that of the control by adopting all the optimal factors in the culture system.
