Fungal degradation of lignocellulose in coffee waste

Every year, 10 billion kilograms of coffee are produced, which then end up as waste after consumption. Coffee is a lignocellulosic biomass that could be a potential source of biofuel, but to process it, it is necessary to rid it of the lignin. In this study, we analysed the biodegradation potential of coffee waste with the white rot fungi Trametes versicolor, Pleurotus dryinus, Irpex lacteus and Bjerkandera adusta and the brown rot fungus Fomitopsis pinicola, in addition to evaluating their biological activity and enzyme release efficiency through the analysis of the concentrations of laccase, cellulase, reducing sugars and carbohydrates in the collected samples. The data obtained in the study examines the effectiveness of different species of fungi on coffee as the substrate used.
