Several release experiments in which the release of Cand. Endoriftia persephone from the trophosome of Riftia pachyptila and their ability to “escape” back into the environment conducted with high-pressure vessels. To investigate how this microbe manages to escape I incubated with 13C glycine and 13C glucose for further analyses with NanoSIMS. To investigate how Endoriftia responses to an uncooperative host not providing sulfide to the symbiont I incubated tubeworms under oxic conditions for 2 days. The molecular response will be studied with transcriptomics.
