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.
A bacteriophage is a virus that infects bacteria. Bacteriophages, first discovered around 1915, have played a unique role in viral biology. They are perhaps the best understood viruses, yet at the same time, their structure can be extraordinarily complex.emperate viruses are those that reproduce without killing their host cell. Typically they reproduce in two ways: through the lytic cycle and the lysogenic cycle. In the lysogenic cycle, the phage's DNA recombines with the bacterial chromosome. Once it has inserted itself, it is known as a prophage.
