Bacterial component of the plankton that drifts in the water column of both seawater and freshwater ecosystems.
The name bacterioplankton comes from the association of the Greek word πλαγκτος “planktós,” meaning “wanderer” or “drifter,” and bacterium, a word coined in the nineteenth century by Christian Gottfried Ehrenberg (Thurman, 1997). In contrast to land, microbes drive the ecology of the aquatic environments both as producers and consumers of fixed carbon. Their colossal biomass vastly outreaches the ones of all other members of the oceanic and freshwaters biota. Considering its size, the Ocean encompasses more bacteria than the count of known stars (estimated to 1021) in the Universe. Though its role in aquatic ecosystems was for long eluded, the bacterioplankton carries out the largest fraction of the biological activity and occupies a range of ecological niches.
