A Review of the Biotechnological Potential of Cave Fungi: A Toolbox for the Future

The study of the intersection between biodiversity and biotechnology has revealed a rich source of innovations. Fungi, with their vast range of morphologies and lifestyles, thrive in various habitats, including caves. With impressive metabolic characteristics, they play a key role in producing essential biotechnological compounds for various economic sectors. This paper aims to consolidate evidence on the biotechnological potential of fungi isolated from caves, highlighting the urgency of conserving and exploring these ecosystems. For this purpose, we conducted a comprehensive literature search using scientific databases (SciELO, Medline Complete, Medline/PubMed, Web of Science, Scopus (Elsevier), and Google Scholar). We adopted an interdisciplinary approach by collecting information from 22 papers published between 2013 and 2024. Based on these data, our survey revealed broad potential, including antimicrobial compounds, antioxidants, antitumor agents, enzymes, and organic acids. We emphasize that accurately identifying and depositing fungal isolates in reference collections are crucial for reliable research and effective industrial applications, driving metabolic bioactivity and the production of substances with the potential to inhibit pathogens. Conserving and protecting the cave environment is imperative, considering its continuous potential for discovery and contribution to scientific advancement.
