The Burkholderiales are an order of Betaproteobacteria in the phylum Pseudomonadota. Like all Pseudomonadota, they are Gram-negative. They include several pathogenic bacteria, including species of Burkholderia, Bordetella, and Ralstonia. They also include Oxalobacter and related genera, which are unusual in using oxalic acid as their source of carbon. Other well-studied genera include Alcaligenes, Cupriavidus, Achromobacter, Comamonas, Delftia, Massilia, Duganella, Janthinobacterium, Polynucleobacter, non-pathogenic Paraburkholderia, Caballeronia, Polaromonas, Thiomonas, Collimonas, Hydrogenophaga, Sphaerotilus, Variovorax, Acidovorax, Rubrivivax and Rhodoferax, and Herbaspirillum.
Mycobacterium chubuense is a species of the phylum Actinomycetota, belonging to the genus Mycobacterium.
Mycobacterium monacense is a yellow-pigmented, non-photochromogenic species of mycobacterium named after Monacum, the Latin name of the German city Munich where the first strain was isolated. It grows in less than a week on solid medium.
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.
Polynucleobacter necessarius is a bacterium of the genus Polynucleobacter.
Polynucleobacter cosmopolitanus is an aerobic, catalase- and oxidase-positive, chemo-organotrophic, nonmotile bacterium of the genus Polynucleobacter, isolated from freshwater habitats in Eurasia, South America, North America, Africa, Oceania, the Hawaiian Archipelago, in lakes located in Japan, and a river estuary of northern Taiwan. The type strain of the species was isolated from Lake Mondsee in Austria.
Polynucleobacter difficilis is an aerobic, catalase- and oxidase-positive, chemo-organotrophic, nonmotile, freshwater bacterium of the genus Polynucleobacter, isolated from the Lake Sevan from a depth of 60 m in Armenia.
Polynucleobacter rarus is an aerobic, chemo-organotrophic, catalase- and oxidase-positive, nonmotile bacterium of the genus Polynucleobacter, isolated from an acidic lake in Wisconsin.
The Feldsee is a lake in southern Baden-Württemberg at the foot of the Feldberg east of Freiburg im Breisgau in Germany. It is part of the Southern Black Forest Nature Park.
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 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 species represents planktonic bacteria (bacterioplankton) dwelling in alkaline freshwater systems. The species name refers to the origin of the type strain.
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.
Polynucleobacter victoriensis is an aerobic, chemo-organotrophic, non-motile, free-living bacterium of the genus Polynucleobacter.
