One of the most important objectives pursued by BIOLAC through its support of biotechnology in Latin America is the valorization of the extraordinary biodiversity of the region. Beyond its ecological and cultural significance, Latin American biodiversity represents an immense and still largely unexplored reservoir of biochemical innovation. In the global search for new bioactive molecules—particularly urgently needed antimicrobials—humans increasingly look to nature’s own battlefields, where organisms have been refining chemical defense strategies over millions of years. Among these, slow‑growing lichens inhabiting resource‑poor ecosystems such as high‑altitude Páramos stand out as remarkable examples of resilience. These organisms depend on complex symbioses, including associated bacteria, to defend themselves against microbial competitors, predators, and parasites, making them especially promising sources of novel antimicrobial compounds.
In this context, Fellow Emerson Arciniegas' project represents a compelling illustration of how cutting‑edge biotechnology can be rooted in the conservation and study of native ecosystems. The identification of antimicrobial compounds from actinobacteria associated with lichens from Colombian páramos—some of which appear to be previously undescribed—highlights not only the scientific merit of the work, but also the strategic importance of preserving and studying these ecosystems before their biological wealth is irreversibly lost.
Ultimately, this research serves as a powerful reminder that such discoveries are only possible if natural ecosystems are conserved in their full complexity. Páramos are among the ecosystems most vulnerable to global warming and anthropogenic pressure, and their degradation could mean the disappearance of countless microorganisms and chemical entities before we even become aware of their existence. Mr. Arciniegas’ project underscores how biodiversity conservation and biotechnology are deeply interconnected, and how safeguarding ecosystems like the páramos is essential not only for environmental sustainability, but also for future life‑changing scientific and medical breakthroughs.
The successful execution of this fellowship was made possible by the expert mentorship and institutional support provided by Prof. Gilles van Wezel (Leiden University) and Prof. Leonardo Castellanos Hernández (Universidad Nacional de Colombia). Their guidance was instrumental in the application of advanced methodologies in genome mining, metabolomics, and natural product analysis, including the use of the nanoRAPIDS platform for bioactivity‑guided compound identification. The collaboration between Leiden University and the Universidad Nacional de Colombia exemplifies the value of international partnerships in strengthening regional scientific capacity and advancing biodiversity‑based biotechnology research.
