(Translated via Google) A significant part of the world is characterized by low concentrations and chlorophyll concentrations. In these oligotrophic environments, bacteria are very abundant and play a vital role in the remineralization of the dissolved organic matter. Bacteria adapted to oligotrophic waters differ from those adapted to richer environments by some genetic and metabolic characteristics. Culture techniques in bacteriology are based on rich media and do not allow the growth of most marine bacteria. New techniques have been developed for the culture of oligotrophic bacteria, which allow to isolate unknown bacteria. Pelagibacter ubique and Sphingopyxis alaskensis belong to these bacteria recently isolated from the marine environment and their study yielded better understanding of how marine bacteria adapt to oligotrophic conditions.
