  • Resumen
    • Mediterranean agro-industrial wastes are generated in huge amounts, mainly from olive mills, wineries and breweries. These wastes management poses serious environmental problems to the regions where they are generated. The objective of this work is to use the agro-industrial wastes as sources of phenolic compounds, improving its extraction from mixtures of olive pomace, brewer’s spent grain and vine-shoot trimmings by solid-state fermentation (SSF) with A. niger and to obtain enzymes such as xylanases, cellulases and β-glucosidase. The results allowed to obtain the combination of wastes that maximized enzymes production and increased total phenolic compounds and antioxidant activity by SSF. Therefore, SSF showed to be an interesting valorization strategy to exploit agro-industrial wastes following the concept of circular economy.
