Metabolic interactions between coral animal and endolithic bacterial communities.

ABSTRACT: Coral skeletons constitute sources of nutrients and energy for holobiont. Although bacteria predominate in endolithic microbiomes of corals, their ecological functions have long been masked by those of symbiotic microalgae. In the skeleton of Isopora palifera, previous studies showed the absence of microalgae and a green layer dominated by green sulfur bacteria. This system, which excludes a contribution from microalgae, provides a perfect model for studying the role of endolithic bacteria in corals. Using this model, we examined the metabolite profile and translocation of organic matter between coral tissue and skeleton. Chromatography-time-of-flight-mass spectrometry and ultra-high-performance liquid chromatography tandem mass spectrometry revealed distinct metabolic profiles in t
