The communities of marine bacteria that assemble around living microphytoplankton are predictably dominated by three taxonomic groups, each of which specializes in the use or transport of different components of the available metabolite pool: Rhodobacterales transport small and polar metabolites,...
The marine labile dissolved organic carbon (DOC) pool is a dynamic reservoir of thousands of molecules. After excretion or release by phytoplankton and other microbes, metabolites are rapidly consumed, resulting in very low standing concentrations (picomolar to low nanomolar). To date, marine phy...
The communities of marine bacteria that assemble around living microphytoplankton are predictably dominated by three taxonomic groups, each of which specializes in different components of the available metabolite pool: Rhodobacterales transport small and polar metabolites, Flavobacteriia use carb...
In annually reoccurring patterns, microalgae form blooms that persist and decline thereby contributing massively to global biogeochemical cycles. The decline of blooms is mainly caused by nutrient limitation and goes ahead with the aging of individual algal cells. Nutrient intake can re-initiate ...
The viral shunt is a fundamental ecosystem process which diverts the flux of organic carbon fixed through photosynthesis during algal bloom events from heterotrophic grazers to bacteria. Through the extracellular release of metabolites, lytic viral infections supply 2-10% of photosynthetically fi...
