Zusammenfassung

Communities of photosynthesising and nutrient-cycling microorganismsare fundamental to life on Earth. They rely on chemical crosstalk viaa range of specific molecules to mediate their interactions,"communicate" and function efficiently. Microalgae-bacteriacommunities in aquatic systems share micro-habitats where abioticconditions fluctuate substantially on a diurnal time scale, becausethe interplay of photosynthesis and respiration causes steep gradientsof pH and oxygen. Such abiotic conditions have the potential toinactivate "communication chemicals" by altering the molecules andthereby disru...
