Physiological Regulation of Edible and Medicinal Higher Basidiomycetes Lignocellulolytic Enzyme Activity
摘要
The biosynthesis of cellulases and xylanases in all white-rot higher Basidiomycetes is inducible by addition of cellulose as a carbon source. The characteristic feature of brown-rot fungi is constitutive synthesis of enzymes even in the presence of glucose as carbon source. However, cellulases and xylanases of Piptoporus betulinus are inducible enzymes in the presence of cellobiose as the sole carbon source. Catabolite repression of cellulase and xylanase synthesis in the presence of an easily metabolizable carbon source is widespread in all fungi with inducible enzymes synthesis. The role of an easily metabolizable carbon source in regulation of laccase production is established. The use of cellobiose instead of avicel as a carbon source results in a 20-fold increase of Cerrena unicolor laccase activity. Mannitol was the best carbon source for Pleurotus ostreatus and Phlebia radiata, whereas xylan ensured the highest laccase activity of Coriolus pubescens. Addition of 2,5-xylidine enhanced laccase production 4- to 10-fold by Cerrena unicolor, Coriolus pubescens, Panus tigrinus, and Pleurotus ostreatus.
