In the last two decades, a significant amount of work aimed at studying the ability of the whiterotfungus Coriolopsis rigida (Berk. & Mont.) Murrill to degrade lignocellulose, wood extractives,as well as several hazardous pollutants like dyes and aliphatic and aromatic fractions of crudeoil, including polycyclic aromatic hydrocarbons, has been performed. Additionally, C. rigidain association with arbuscular mycorrhizal fungi appears to enhance plant growth, albeit thephysiological and molecular bases of this effect remain to be elucidated. The ability of C. rigidato degrade lignin and lignin-related compounds and the capacity to transform the aromaticfraction of crude oil in the soil might be partially ascribed to its ligninolytic enzyme system.Two extracellular laccases are the only enzymatic components of its lignin-degrading system. Wereviewed the most relevant findings regarding the activity and role of C. rigida LPSC N.º 232 andits laccases and discussed the work that remains to be done in order to assess, more precisely, thepotential use of this fungus and its extracellular enzymes as a model in several applied processes.
