Termine Fungiculture – A Hidden Treasure Trove
Termites and their symbionts
Studying the microbiome of social insects, such as termites, helps to identify new aspects of small-molecule mediated symbiotic relations. At the same time it serves platform to identify new antibacterial and antifungal agents.
The fungus-growing termite system is a prime example of multilateral symbiosis. The ancient farming symbiosis involves a termite host (Macrotermitinae), a specialized fungal mutualist (Termitomyces) maintained in an optimized fungal garden system (fungus comb), the presence of complex and highly adapted bacterial communities within the insect gut and fungus comb, and the co-evolved garden weed (Pseudoxylaria).
Natural Products from protective symbionts
Within this project, we aim to isolate, characterize and understand the role of natural products produced by microorganisms associated with fungus-growing termites. We used various different culturing techniques to isolate termite-associated microbes and pursued the whole genome sequence of several key isolates. Subsequent chemical analysis of our isolates in axenic and co-cultures revealed several new natural product classes showing a diverse set of biological activities.
Biosynthetic pathway analysis
We have sequenced the genomes of selected new microbial species to analyze their biosynthetic potential and potentially detect new natural products. The comparative analysis of the acquired genomic information likely reveals new biosynthetic enzymes and new biochemical transformations.
