The Gemmatimonadota are a phylum of bacteria established in 2003. The phylum contains two classes Gemmatimonadetes and Longimicrobia.
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.
Comamonas denitrificans is a Gram-negative, oxidase- and catalase-positive, motile bacterium with a polar flagellum from the genus Comamonas and family Comamonadaceae, which was isolated from an activated sludge. Its colonies are yellow-white colored. Unlike other species of Comamonas, C. denitrificans can reduce nitrate to nitrogen gas.
Hydrogenophaga bisanensis is a Gram-negative, non-spore-forming, rod-shaped bacterium from the Comamonadaceae family, which was isolated from wastewater from a textile dye works in Korea. Colonies of H. bisanensis are moderate yellow in color.
Hydrogenophaga caeni is a Gram-negative, anaerobic, catalase- and oxidase-positive, motile bacterium from the Comamonadaceae family, with a single polar flagellum, which was isolated from an activated sludge. Colonies of H. caeni are white colored.
Hydrogenophaga defluvii is a Gram-negative, oxidase-positive, rod-shaped, motile bacterium from the Comamonadaceae family, which was isolated from wastewater. Colonies of H. defluvii are pale yellow in color.
Chelativorans multitrophicus is a Gram-negative, aerobic, non-motile bacteria from the genus of Chelativorans which was isolated from soil of activated sludge from industrial wastewater treatment plants in Switzerland. Chelativorans multitrophicus has the ability to degrade EDTA.
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.
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.
Millisia brevis is a mycolic acid producing bacterium from the family Nocardiaceae which has been isolated from activated sludge in Australia.
Xenophilus azovorans is a bacterium from the genus Xenophilus which has been isolated from soil in Switzerland.
Caenibius tardaugens is an oestradiol-degrading bacterium from the family Hyphomicrobiaceae which has been isolated from activated sludge from a sewage treatment plant in Japan.
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.
Ornithinimicrobium pekingense is a Gram-positive bacterium species from the genus Ornithinimicrobium which has been isolated from activated sludge.
Diaphorobacter nitroreducens is a Gram-negative bacterium from the genus of Diaphorobacter which has been isolated from activated sludge in Japan.
Hydrogenophaga aquatica is a Gram-negative, rod-shaped and aerobic bacterium from the genus of Hydrogenophaga which has been isolated from a hot spring.
Hydrogenophaga crassostreae is a Gram-negative, rod-shaped, aerobic and motile bacterium from the genus of Hydrogenophaga which has been isolated from the oyster Crassostrea gigas.
Hydrogenophaga soli is a Gram-negative, rod-shaped, strictly aerobic and motile bacterium from the genus of Hydrogenophaga which has been isolated from soil from a rice field from Goyang in Korea.
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.
