Microbes of the surface ocean release, consume, and exchange labile metabolites at time
scales of minutes to days. The details of this important step in the global carbon cycle remain …

Prokaryotes play a central role in aquatic ecosystems by consuming approximately half of
the organic matter produced by aquatic primary production, of which a fraction is used for …

Photosynthesis in the surface ocean produces approximately 100 gigatonnes of organic
carbon per year, of which 5 to 15 per cent is exported to the deep ocean,. The rate at which …

Bacterioplankton respiration (BR) may represent the largest single sink of organic carbon in
the biosphere and constitutes an important driver of atmospheric carbon dioxide (CO2) …

Proteorhodopsin (PR) is present in half of surface ocean bacterioplankton, where its light-
driven proton pum** provides energy to cells. Indeed, PR promotes growth or survival in …

Human-induced ocean acidification impacts marine life. Marine bacteria are major drivers of
biogeochemical nutrient cycles and energy fluxes; hence, understanding their performance …

Quantifying the contribution of marine microorganisms to carbon and nitrogen cycles and
their response to predicted ocean warming is one of the main challenges of microbial …

The increasing quantity of plastic waste in the ocean is providing a growing and more
widespread novel habitat for microbes. Plastics have taxonomically distinct microbial …

Deep ocean microorganisms consume particulate organic matter that is produced in the
surface ocean and exported to deeper depths. Such consumption not only enriches …

The oceans teem with heterotrophic bacterioplankton that play an appreciable role in the
uptake of dissolved organic carbon (DOC) derived from phytoplankton net primary …
