Bacterioplankton are bacteria and archaea, which play an important role in remineralising organic material down the water column (note that many phytoplankton are also bacterioplankton). Plankton are found throughout the oceans, seas and lakes of Earth.
Bactericidal: able to kill bacteria; e.g., serum has innate ability to kill many microorganisms. Bacteriophage (phage): a virus whose host is a bacterium; infects host bacterial cell resulting in either replication and transmissible lysis (lytic) or lysogeny (lysogenic prophage) Temperate phage: avirulent bacteriophage that rarely causes lysis of host cells; capable of entering into lysogeny.
