Abstract Transparent Exopolymer Particles (TEP) have received considerable attention
since they were first described in the ocean more than 20 years ago. This is because of their …

Heterotrophic bacteria are the most abundant organisms on the planet and dominate
oceanic biogeochemical cycles, including that of carbon. Their role in polar waters has been …

Grazing rate estimates indicate that approximately half of the bacterivory in oligotrophic
oceans is due to mixotrophic flagellates (MFs). However, most estimations have considered …

Microbial plankton respiration is the key determinant in the balance between the storage of
organic carbon in the oceans or its conversion to carbon dioxide with accompanying …

Phytoplankton and heterotrophic prokaryotes are major components of the microbial food
web and interact continuously: heterotrophic prokaryotes utilize the dissolved organic …

Previsions of a warmer ocean as a consequence of climatic change point to a 2–6° C
temperature rise during this century in surface oceanic waters. Heterotrophic bacteria …

The deep chlorophyll maximum (DCM) is a ubiquitous feature of phytoplankton vertical
distribution in stratified waters that is relevant to our understanding of the mechanisms that …

The direct respiration of sinking organic matter by attached bacteria is often invoked as the
dominant sink for settling particles in the mesopelagic ocean. However, other processes …

Marine heterotrophic Bacteria (or referred to as bacteria) play an important role in the ocean
carbon cycle by utilizing, respiring, and remineralizing organic matter exported from the …

Marine microbial communities differ genetically, metabolically, and ecologically according to
their lifestyle, and they may respond differently to environmental changes. In this study, we …
