Microbial Symbionts of Hydractinia

Microbes associated with marine invertebrates are well-known to harbor an enormous biosynthetic potential. We combine new bioassays, genome sequencing and mining strategies to identify the encoded secondary metabolites with unique chemical scaffolds and potential pharmaceutical application.

Microorganisms protect and shape the colonial hydroid polyp Hydraktinia
