The Nocardiaceae are a family of aerobic, non-fastidious, high G+C, Gram-positive actinomycetes that are commonly found in soil and water. Members of this family have been isolated from Antarctic soils. Nocardiaceae present coccobacilli, filamentous or, rarely, fragmented and palisading forms, and filamentous species grow in a branching morphological pattern similar to fungal hyphae.
Acidovorax caeni is a gram-negative, catalase- and oxidase-positive, rod-shaped bacterium from the Comamonadaceae family that was isolated from the activated sludge of a wastewater treatment plant in Belgium. Colonies are yellow–brown.
Neomegalonema perideroedes is a filamentous bacterium from the genus of Neomegalonema which has been isolated from activated bulking sludge from industrial wastewater in Grindsted in Denmark.
Gordonia defluvii is a Gram-positive and non-motile bacterium from the genus Gordonia which has been isolated from activated sludge foams in Australia.
Tsukamurella pseudospumae is a bacterium from the genus Tsukamurella which has been isolated from activated sludge foam from an activated sludge treatment plant in England.
Chryseomicrobium is a bacteria genus from the family of Planococcaceae.
Novosphingobium chloroacetimidivorans is a Gram-negative, chloroacetamide-degrading and non-spore-forming bacterium from the genus Novosphingobium which has been isolated from activated sludge from a wastewater treatment plant in Kunshan City in China.
Sphingobacterium caeni is a gram-negative, non-spore-forming, rod-shaped and non-motile bacterium from the genus of Sphingobacterium which has been isolated from activated sludge.
Roseomonas eburnea is a species of Gram negative, strictly aerobic, coccobacilli-shaped, ivory-colored bacterium. It was first isolated from activated sludge from an herbicide-manufacturing wastewater treatment facility in Jiangsu province, China, and the species was first proposed in 2016. R. eburnea, unlike most species of Roseomonas which are pink or light red, is ivory-pigmented. The species name comes from Latin eburnea. R. chloroacetimidivorans was isolated at the same time as R. eburnea.
Janibacter is a genus of Gram positive, nonmotile, non-sporeforming bacteria. The genus name is derived from the two-faced Roman god Janus, referring to the fact that the cells of the original strain could be rod-shaped or coccoid.
Ornithinimicrobium pekingense is a Gram-positive bacterium species from the genus Ornithinimicrobium which has been isolated from activated sludge.
Ottowia is a genus of bacteria from the family of Comamonadaceae.
Ottowia thiooxydans is a Gram-staining, facultatively anaerobic, N2O-producing and non-motile bacterium from the genus Ottowia which has been isolated from activated sludge from Munich in Germany.
Kineosphaera is a Gram-positive, strictly aerobic non-spore-forming and motile genus of bacteria from the family of Dermatophilaceae. Kineosphaera limosa has been isolated from activated sludge from Ibaraki Prefecture in Japan.
Dokdonella is a genus of bacteria from the family of Rhodanobacteraceae. Dokdonella is named after the island Dokdo.
Dokdonella kunshanensis is a Gram-negative, aerobic, non-spore-formin and non-motile bacterium from the genus of Dokdonella which has been isolated from activated sludge from a wastewater treatment plant in China.
Tahibacter is a genus of Pseudomonadota from the family of Rhodanobacteraceae.
Pseudoclavibacter chungangensis is a Gram-positive and non-spore-forming bacterium from the genus Pseudoclavibacter which has been isolated from activated sludge from Cheonan in Korea.
Flexivirga caeni is a Gram-positive, strictly aerobic, non-spore-forming and non-motile bacterium from the genus Flexivirga which has been isolated from activated sludge.
Prosthecobacter algae is a Gram-negative, facultatively anaerobic and fusiform-shaped bacterium from the genus Prosthecobacter which has been isolated from activated sludge.
