Cyanobacterial Natural Products

The Cyanobacterial Natural Products research team studies the fascinating secondary metabolism of an important group of photosynthetic microbes: Cyanobacteria. Using a highly multidisciplinary approach, ranging from NMR spectroscopy to genome sequencing, and a blend of discovery- and hypothesis-based science, lab members investigate the chemistry, biosynthesis and ecology of cyanobacterial secondary metabolites. The team is particularly focused on studying compounds that contain fatty-acid residues and on the unusual enzymes that modify them, and on the discovery of secondary metabolites using genome-informed strategies.

The novel compounds unearthed by the Cyanobacterial Natural Products team are evaluated in terms of biological activity, in particular their pharmacologically- and ecologically-relevant properties. These efforts are part of CIIMAR’s Blue Biotechnology effort to add value to the biological diversity found in our oceans.
