Extracellular laccase production in brown-rot fungus Coniophora puteana
Kwang-Ho Lee, Seung-Gon Wi, Yoon Soo Kim
Coniophora puteana, one of representing brown-rot fungus, was investigated in terms of extracellular ligninolytic enzyme production. Three fungal strains of C. puteana were inoculated in liquid culture medium with sawdust of pine and oak wood. Extracellular laccase production was observed in some strains of C. puteana in the culture medium with sawdust of oak wood. The highest activity occurred at the beginning stage of cultivation. The present work suggests that some brown-rot fungi may have a greater ligninolytic capacity than previously thought and a reappraisal is necessary for the elucidation of lignin degrading enzyme system(s) in brown-rot fungi.
