| dc.description |
The extracellular lignocellulolytic enzymes secreted by Porodaedalea pini were investigated for their
ability to degrade the wood of Picea jezoensis over various time periods. In addition, changes in wood
chemical component contents were also investigated. Enzyme production and wood degradation by
P. pini significantly increased starting at 60 days of incubation. The total lignin, holocellulose, and acellulose
contents, as well as pH, decreased during the degradation process, while hot water, 1% NaOH,
and ethanol-toluene extract contents significantly increased. These results indicate that P. pini simultaneously
degraded the lignin and polysaccharides of P. jezoensis wood. Additionally, P. pini continuously
produced xylanase, b-glucosidase, and endoglucanase with higher activities than those of exoglucanase
and cellobiose dehydrogenase. Manganese(II)-dependent peroxidase showed the highest ligninolytic
activity, followed by lignin peroxidase and laccase. These results indicate that P. pini produces a variety of
lignocellulolytic enzymes, and that the produced enzymes contribute to the degradation of P. jezoensis
wood components. |
