The wood decay fungus Cerrena unicolor adjusts its metabolism to grow on various types of wood and light conditions

Cerrena unicolor is a wood-degrading basidiomycete with ecological and biotechnological importance. Comprehensive Biolog-based analysis was performed to assess the metabolic capabilities and ... arbutin. The obtained picture of C. unicolor metabolism showed that the fungus abilities to decompose woody plant material are influenced by various environmental factors. Introduction Wood degrading
