Zusammenfassung

Communities of photosynthesising and nutrient-cycling microorganisms are fundamental to life on Earth. They rely on chemical crosstalk via a range of specific molecules to mediate their interactions, "communicate" and function efficiently. Microalgae-bacteria communities in aquatic systems share micro-habitats where abiotic conditions fluctuate substantially on a diurnal time scale, because the interplay of photosynthesis and respiration causes steep gradients of pH and oxygen. Such abiotic conditions have the potential to inactivate "communication chemicals" by altering the molecules and ther...
