Developing experimentally tractable models for sponge-microbe symbioses

My laboratory has a long-term commitment to develop new technologies and procedures towards developing an experimental model for sponge-microbe symbioses. In this context, we have made considerable efforts to increase access and tractability of sponge symbioses. Marine gnotobiotic biosafety S1 animal housing facilities allow experimentation in a germ-free laboratory environment. Experiments are being run (Lara Schmittmann) to determine the ideal antibiotic cocktail composition and concentration to effectively remove bacteria without causing harm to the sponges. We are further making increasingly use of sponge genomic and transcriptomic resources. Our overarching aim is to move sponge symbioses from an exploratory type of research into the arena of experimental models for host-microbe interactions.
