Emiliania huxleyi-Bacteria Interactions under Increasing CO₂ Concentrations.

ABSTRACT: The interactions established between marine microbes, namely phytoplankton-bacteria, are key to the balance of organic matter export to depth and recycling in the surface ocean. Still, their role in the response of phytoplankton to rising CO₂ concentrations is poorly understood. Here, we show that the response of the cosmopolitan Emiliania huxleyi (E. huxleyi) to increasing CO₂ is affected by the coexistence with bacteria. Specifically, decreased growth rate of E. huxleyi at enhanced CO₂ concentrations was amplified in the bloom phase (potentially also related to nutrient concentrations) and with the coexistence with Idiomarina abyssalis (I. abyssalis) and Brachybacterium sp. In addition, enhanced CO₂ con
