Polynucleobacter Antarcticus
''Polynucleobacter'' is a genus of bacteria, originally established by Heckmann and Schmidt (1987) to exclusively harbor obligate endosymbionts of ciliates belonging to the genus ''Euplotes''. Recently, several new ''Polynucleobacter'' species were described, which all represent free-living (i.e. not host-associated) planktonic freshwater bacteria. Thus, the genus ''Polynucleobacter'' currently includes one species containing obligate endosymbionts of ciliates and nine species representing free-living planktonic strains. The type strains of the planktonic species were isolated from freshwater systems located in Antarctica, Armenia, Austria, China, Czech Republic, Finland, France, Germany, Norway, Spain, Uganda, and the United States. Currently, the genus harbors 31 species. Free-living ''Poynucleobacter'' bacteria represent important members of bacterioplankton in freshwater systems such as lakes, ponds, and streams.

Bacteria
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria are vital in many stages of the nutrient cycle by recycling nutrients such as the fixation of nitrogen from the atmosphere. The nutrient cycle includes the decomposition of dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulphide and methane, to energy. Bacteria also live in symbiotic and parasitic relationsh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polynucleobacter Paneuropaeus
''Polynucleobacter paneuropaeus'' is an aerobic, facultatively anaerobic, chemo-organotrophic, non-motile, free-living bacterium of the genus ''Polynucleobacter''. The type strain was isolated from a small acidic lake located in Norway. Other strains representing this species were isolated from acidic or circum-neutral lakes and ponds located in Finland, Germany, The Czech Republic, Austria and France. The northernmost observation of this species was reported for the Pasvikdalen valley in the Finnmark, Norway near Kirkenes at a latitude of about 69°N, while the southernmost known occurrence was reported for Lake Creno (Lac de Creno) at the Mediterranean island Corsica, France near the village Soccia at a latitude of about 42°N. The type strain dwells as a free-living, planktonic bacterium in the water column of the lake, thus is part of freshwater bacterioplankton Bacterioplankton refers to the bacterial component of the plankton that drifts in the water column.

Polynucleobacter Necessarius
''Polynucleobacter necessarius'' is a bacterium of the genus ''Polynucleobacter''. Bacteria These bacteria were discovered by the German microbiologist Klaus Heckmann in the cytoplasm of the ciliate ''Euplotes aediculatus'' and designated as ''Omikron'' (''Omicron'' in English literature). In 1987 ''Omikron'' / ''Omicron'' was scientifically described by Klaus Heckmann and Helmut Schmidt as the new species (and genus) ''Polynucleobacter necessarius''. Later free-living ''Polynucleobacter'' bacteria were discovered in the water columns of lakes and ponds. These planktonic, non-endosymbiontic members of the genus ''Polynucleobacter'' were initially assigned to a new subspecies of the species ''P. necessarius'' but later transferred to separate species. Since the last revision of the species, it contains exclusively obligate endosymbionts dwelling in cells of the ciliate ''Euplotes aediculatus'' and related species. This is in contrast to other species of the genus ''Polynucleobacte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polynucleobacter Meluiroseus
''Polynucleobacter meluiroseus'' is an aerobic, chemo-organotrophic, non-motile, free-living bacterium of the genus ''Polynucleobacter''. The type strain was isolated from the mountain lake (1,710 meters) Lac de Melu located in the Restonica Valley on the Mediterranean island Corsica, France near to the commune of Corte. The type strain of ''P. meluiroseus'' is remarkable because of its unusual pigmentation compared to other ''Polynucleobacter'' strains, as well as due to the presence of a Proteorhodopsin gene in the genome of the strain. Furthermore, the 16S rRNA gene of the type strain contains an unusual indel previously only known from uncultured ''Polynucleobacter'' strains detected by cultivation-independent methods in mountain lakes located in the Pyrenees. The type strain dwells as a free-living, planktonic bacterium in the water column of the lake, thus is part of freshwater bacterioplankton Bacterioplankton refers to the bacterial component of the plankton that ...
