Lac de Melu is a lake in Corsica, France. At an elevation of 1,710 metres (5,610 ft), its surface area is 0.065 square kilometres (0.025 sq mi). The lake is the source of the Restonica River.
Polynucleobacter is a genus of Proteobacteria, originally established by Heckmann and Schmidt (1987) to exclusively harbor obligate endosymbionts of ciliates belonging to the genus Euplotes.
Polynucleobacter acidiphobus is an aerobic, chemo-organotrophic, catalase- and oxidase-positive, nonmotile bacterium of the genus Polynucleobacter. The type strain was isolated from a rock pool which was filled with fresh water in a mountain brook in Corsica in France.

Polynucleobacter asymbioticus is an aerobic, catalase- and oxidase-positive, chemo-organotrophic, nonmotile, free-living bacterium of the genus Polynucleobacter. The type strain was isolated from a small pond located in the Austrian Alps in the area of Salzburg and described as a new subspecies of Polynucleobacter necessarius in 2009. The classification of the type strain was hampered by the fact that its closest described relative represented obligate endosymbionts, i.e. P. necessarius, not available as a pure culture suitable for standard tests for delineation of prokaryotic species. Therefore, the strain was preliminarily placed in the subspecies P. necessarius subsp. asymbioticus. Later sequencing of the genome of the type strain revealed that the strain represented a novel species within the genus Polynucleobacter. Therefore, its taxonomic rank was lifted from the subspecies to the species level. Strains of P. asymbioticus dwell as planktonic organisms in acidic, humic-rich freshwater systems. Comparative genome analyses revealed that P. asymbioticus represents an atypical member of the family Burkholderiaceae regarding its small genome size and its passive lifestyle. A recent study used a collection of 37 P. asymbioticus strains isolated from various ponds located in a larger region of the Austrian Alps to gain insights in the evolution of Polynucleobacter bacteria.
Polynucleobacter duraquae is an aerobic, chemo-organotrophic, catalase- and oxidase-positive, sometimes motile, free-living bacterium of the genus Polynucleobacter, isolated from Lake Mondsee in Austria. The species represents planktonic bacteria (bacterioplankton) dwelling in alkaline freshwater systems.
Polynucleobacter wuianus is an aerobic, chemo-organotrophic, catalase- and oxidase-positive, free-living bacterium of the genus Polynucleobacter, isolated from a small pond located in the Austrian Alps in the area of Salzburg. Bacteria affiliated with this species represent planktonic bacteria (bacterioplankton) dwelling in acidic freshwater systems. The species was named after the Chinese limnologist and microbiologist Qinglong L. Wu who isolated the type strain.
Polynucleobacter sinensis is an aerobic, chemo-organotrophic, catalase- and oxidase-positive, free-living bacterium of the genus Polynucleobacter, isolated from a freshwater pond in China. The species represents planktonic bacteria (bacterioplankton) dwelling in non-acidic freshwater systems. The species name refers to the origin of the type strain from China.
Polynucleobacter yangtzensis is an aerobic, chemo-organotrophic, catalase- and oxidase-positive, sometimes motile, free-living bacterium of the genus Polynucleobacter, isolated from Yangtze River in the City of Nanjing (China).

The Silvanigrellales are an order of the phylum Proteobacteria. They include currently only the single family Silvanigrellaceae.
The Silvanigrellaceae are the only family of the order Silvanigrellales, of the class Oligoflexia, of the phylum Proteobacteria. This family currently harbors the two genera Silvanigrella and Fluviispira
Silvanigrella aquatica is a bacterial species., of the phylum Proteobacteria. The type strain was isolated from the small lake Nonnenmattweiher located in the Southern Black Forest in Germany. This species is currently the only species in the genus Silvanigrella, which is the only genus in the family Silvanigrellaceae, which is the only family in the order Silvanigrellales. The order Silvanigrellales is one of only four orders in the class Oligoflexia. The type strain MWH-Nonnen-W8red is remarkable due to its low GC content, its pigmentation and its plastic morphology. Of further interest is the relative close relationship of S. aquatica to "Spirobacillus cienkowskii" known as pathogens of daphnids (Daphnia), which are commonly called water fleas. However, S. aquatica is assumed to be a non-pathogenic free-living species. The genome of the type strain was sequenced,
Silvanigrella is a genus, of the phylum Proteobacteria. The genus currently contains with Silvanigrella aquatic and Silvanigrella paludirubra two taxonomically described species.
Rhodoluna is a Gram-positive, non-spore-forming and non-motile genus of bacteria from the family of Microbacteriaceae. The type strain of the only species Rhodoluna lacicola encodes an actinorhodopsin, which is a light-diven proton pump enabling light energy conversion, potentially resulting in a mixotrophic physiology. The type strain of R. lacicola was isolated from Lake Tai in China. The type strain MWH-Ta8 is remarkable for its very small cell size ultramicrobacterium and its small genome size of only 1.4 Mbp. The type strain has a planktonic lifestyle, that is freely floating the water column of aquatic systems. Currently, the genus Rhodoluna contains two described species.
Polynucleobacter meluiroseus is an aerobic, chemo-organotrophic, non-motile, free-living bacterium of the genus Polynucleobacter.
Polynucleobacter campilacus is an aerobic, catalase- and oxidase-positive, chemo-organotrophic, nonmotile, free-living bacterium of the genus Polynucleobacter., The type strain was isolated from Lake Feldsee located in the Southern Black Forest in Germany. The species epithet "campilacus" refers to the origin of the type strain from this lake. The complete genome sequence of the strain was determined. Among the described Polynucleobacter species, P. campilacus is closest related to P. hirudinilacicola.
