Laccases have been paid much attention both from researchers and from industries in recent decades due to their possible involvement in the transformation of a wide phenolic and non-phenolic compounds and lignin, as well as bioremediation of highly recalcitrant aromatic environmental pollulants. In nature, there are several symbioses, synergies or competitions between or among various microorganisms, and interestingly, the secretion of fungal laccase is also involved in the biocontrol phenomenon. It is found that some fungi can promote the production of laccase during interactions with other organisms. This leads us to a possible way to upgrade laccase production to solve environmental problems, and to make or improve pretreatment processes of lignocellulosics such as by interspecies interactions. Therefore, the aim of this study was to screen out the active lignolytic fungi and laccase-promoting interspecies interactions among white-rot fungi and its application to the pretreatment process of lignocellulosic biomass.
