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.

  • shell overgrown with H. echiniata

Marine Bacteria

  • wild isolates of marine bacteria
  • pure isolates of marine bacteria
  • Pseudoalteromonas sp.

Microorganisms protect and shape the colonial hydroid polyp Hydraktinia
