Comamonas is a genus of Proteobacteria . Like all Proteobacteria, they are Gram-negative bacteria. Comamonas species are aerobic organisms and motile using bipolar or polar tufts of one to five flagella.
Comamonas testosteroni is a Gram-negative soil bacterium. Strain I2gfp has been used in bioaugmentation trials, in attempts to treat the industrial byproduct 3-chloroaniline.
Comamonas acidovorans is a Gram-negative, non-spore-forming, aerobic, rod-shaped bacterium from the genus Comamonas and family Comamonadaceae. C. acidovorans occur in soil, mud, and water in Japan, the Netherlands, Great Britain, the US, Spain, and Sweden. It has a major role in natural biodegradation.
Comamonas composti is an aerobic, Gram-negative, rod-shaped, non-spore-forming, weak oxidase-positive, catalase-positive, motile bacterium from the genus Comamonas and family Comamonadaceae, which was isolated from food waste compost.
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.
Comamonas granuli is a Gram-negative, catalase-positive, oxidase-positive, non-spore-forming, motile, rod-shaped bacterium from the genus Comamonas and family Comamonadaceae, which was isolated from microbial granules.
Comamonas guangdongensis is a Gram-negative, anaerobic, motile bacterium from the genus Comamonas and family Comamonadaceae, which was isolated from subterranean forest sediment in Guangdong Province in China.
Comamonas kerstersii is a Gram-negative, oxidase- and catalase-positive, motile bacterium with multitrichous polar flagella from the genus Comamonas and family Comamonadaceae. C. kerstersii is a subgroup of Comamonas terrigena, and has been linked to cases of perforated appendices.
Comamonas koreensis is a Gram-negative, aerobic, oxidase- and catalase-positive, nonfermentative bacterium with no flagella from the genus Comamonas, which was isolated from a wetland sample in Woopo in the Republic of Korea.
Comamonas nitrativorans is a Gram-negative, oxidase- and catalase-positive bacterium from the genus Comamonas, which was isolated from a denitrifying reactor treating landfill leachate. C. nitrativorans has the ability to perform anoxic-reduction of nitrate, nitrite, and nitrous oxide to nitrogen.
Comamonas odontotermitis is a Gram-negative, aerobic, weak oxidase- and catalase-positive, non-spore-forming, rod-shaped, motile bacterium from the genus of Comamonas, which was isolated from the gut of the termite Coptotermes formosanus.
Comamonas terrae is a bacterium from the genus Comamonas, which was isolated from agricultural soil in Thailand. C. terrae has an arsenite-oxidizing ability.
Comamonas terrigena is a Gram-negative, rod-shaped bacterium from the genus Comamonas and the family of Comamonadaceae, which was isolated from contaminated soil in Slovakia. C. terrigena has the ability to degrade phenols.
Comamonas thiooxydans is a Gram-negative, rod-shaped bacterium from the genus Comamonas and family Comamonadaceae, which was isolated from a sulfur spring. C. thiooxydans has the ability to oxidize thiosulfate.
Comamonas zonglianii is a Gram-negative, aerobic, oxidase- and catalase-positive, nonmotile bacterium from the genus Comamonas and family Comamonadaceae, which was isolated from a phenol-contaminated soil. Colonies of C. zonglianii are pale yellow in color.
Pelomonas aquatica is a Gram-negative, rod-shaped, non-spore-forming bacterium from the genus Pelomonas in the family Comamonadaceae. Colonies of P. aquatica are yellowish in color and dark and opaque.
Polaromonas aquatica is a Gram-negative, oxidase- and catalase-positive, rod-shaped, non-spore-forming bacterium from the genus Polaromonas, which was isolated from tap water.
Tepidimonas aquatica is a gram-negative, aerobic, oxidase and catalase-positive thermophilic, rod-shaped, motile bacterium, with one polar flagellum from the genus Tepidimonas, which was isolated from a domestic water tank in Coimbra.
Comamonas phosphati is a Gram-negative, rod-shaped, facultatively anaerobic and non-spore-forming bacterium from the genus Comamonas which has been isolated from a phosphate mine in Yunnan in China.
