This study highlights the importance of discovering new therapeutic alternatives, especially natural compounds that can be used to treat multiresistant pathogens and emerging diseases. The research finds that volatile compounds (VOCs) have the ability to activate biosynthetic pathways of bioactive compounds in Actinomycetes, leading to increased antibiotic production and synthesis of new VOCs. The results demonstrate a novel strategy to exploit the metabolic potential of Actinomycetes and emphasize the significance of studying interactions between different microorganisms sharing the same ecological niche.
The increasing appearance of multiresistant pathogens, as well as emerging diseases, has highlighted the need for new strategies to discover natural compounds that can be used as therapeutic alternatives, especially in the genus Streptomyces, which is one of the largest producers of bioactive metabolites. In recent years, the study of volatile compounds (VOCs) has raised interest because of the variety of their biological properties in addition to their involvement in cell communication. In this work, we analyze the implications of VOCs as mediating molecules capable of inducing the activation of biosynthetic pathways of bioactive compounds in surrounding Actinomycetes. For this purpose, several strains of Streptomyces were co-cultured in chamber devices that allowed VOC exchange while avoiding physical contact. In several of those strains, secondary metabolism was activated by VOCs emitted by companion strains, resulting in increased antibiotic production and synthesis of new VOCs. This study shows a novel strategy to exploit the metabolic potential of Actinomycetes as well as emphasizes the importance of studying the interactions between different microorganisms sharing the same ecological niche.
