Bioeconomy is a way to reduce the carbon footprint of human activities by utilizing enzymes as biocatalysts, with fungal secretomes playing a crucial role in providing services and goods. The complex enzyme sets secreted by filamentous fungi can be utilized as enzyme cocktails to enhance the value of various bioresources.
Bioeconomy is seen as a way to mitigate the carbon footprint of human activities by reducing at least part of the fossil resources-based economy. In this new paradigm of sustainable development, the use of enzymes as biocatalysts will play an increasing role to provide services and goods. In industry, most of multicomponent enzyme cocktails are of fungal origin. Filamentous fungi secrete complex enzyme sets called secretomes that can be utilized as enzyme cocktails to valorize different types of bioresources. In this review, we highlight recent advances in the study of fungal secretomes using improved computational and experimental secretomics methods, the progress in the understanding of industrially important fungi, and the discovery of new enzymatic mechanisms and interplays to degrade renewable resources rich in polysaccharides (e.g. cellulose). We review current biotechnological applications focusing on the benefits and challenges of fungal secretomes for industrial applications with some examples of commercial cocktails of fungal origin containing carbohydrate-active enzymes (CAZymes) and we discuss future trends.
