“…BSSH showed a depleted concentration of hemicelluloses due to the activity of the mushroom (Sitarza et al, 2013). The amount of lignin was also decreased (approximately 30%) by G. lucidum enzymatic activity, as could be expected considering that the mushroom is a white rot fungus (Postemsky et al, 2014).…”

Abstract:The continuous increase in the world energy and chemicals demand requires the development of sustainable alternatives to non-renewable sources of energy. Biomass facilities and biorefineries represent interesting options to gradually replace the present industry based on fossil fuels. Lignocellulose is the most promising feedstock to be used in biorefineries. From a sugar platform perspective, a wide range of fuels and chemicals can be obtained via microbial fermentation processes, being ethanol the most significant lignocellulose-derived fuel. Before fermentation, lignocellulose must be pretreated to overcome its inherent recalcitrant structure and obtain the fermentable sugars. Usually, harsh conditions are required for pretreatment of lignocellulose, producing biomass degradation and releasing different compounds that are inhibitors of the hydrolytic enzymes and fermenting microorganisms. Moreover, the lignin polymer that remains in pretreated materials also affects biomass conversion by limiting the enzymatic hydrolysis. The use of laccases has been considered as a very powerful tool for delignification and detoxification of pretreated lignocellulosic materials, boosting subsequent saccharification and fermentation processes. This review compiles the latest studies about the application of laccases as useful and environmentally friendly delignification and detoxification technology, highlighting the main challenges and possible ways to make possible the integration of these enzymes in future lignocellulose-based industries.

“…The expression system of oxidative enzymes of white-rot fungi is highly regulated by the nutrients that the fungi are exposed to, so that if a fungus can grow on a medium supplemented with lignin, it may produce extracellular enzyme(s) that can promote degradation/ modification of lignin or ligninderived components. Secondly, if such enzyme activity would be supplemented to a lignocellulosic substrate undergoing cellulolytic hydrolysis, then the added enzyme activity might boost the conversion of the cellulose (Sitarz et al, 2013 …”
