Acidobacteriota is a phylum of Gram-negative bacteria. Its members are physiologically diverse and ubiquitous, especially in soils, but are under-represented in culture.
Acinetobacter is a genus of gram-negative bacteria belonging to the wider class of Gammaproteobacteria. Acinetobacter species are oxidase-negative, exhibit twitching motility, and occur in pairs under magnification.
The bacteria capsule is a large structure common to many bacteria. It is a polysaccharide layer that lies outside the cell envelope, and is thus deemed part of the outer envelope of a bacterial cell. It is a well-organized layer, not easily washed off, and it can be the cause of various diseases.
Nitrosomonas is a genus of Gram-negative bacteria, belonging to the Betaproteobacteria. It is one of the five genera of ammonia-oxidizing bacteria and, as an obligate chemolithoautotroph, uses ammonia as an energy source and carbon dioxide as a carbon source in presence of oxygen. Nitrosomonas are important in the global biogeochemical nitrogen cycle, since they increase the bioavailability of nitrogen to plants and in the denitrification, which is important for the release of nitrous oxide, a powerful greenhouse gas. This microbe is photophobic, and usually generate a biofilm matrix, or form clumps with other microbes, to avoid light. Nitrosomonas can be divided into six lineages: the first one includes the species Nitrosomonas europea, Nitrosomonas eutropha, Nitrosomonas halophila, and Nitrosomonas mobilis. The second lineage presents the species Nitrosomonas communis, N. sp. I and N. sp. II, meanwhile the third lineage includes only Nitrosomonas nitrosa. The fourth lineage includes the species Nitrosomonas ureae and Nitrosomonas oligotropha and the fifth and sixth lineages include the species Nitrosomonas marina, N. sp. III, Nitrosomonas estuarii and Nitrosomonas cryotolerans.
Acinetobacter calcoaceticus is a bacterial species of the genus Acinetobacter. It is a nonmotile, Gram-negative coccobacillus. It grows under aerobic conditions, is catalase positive and oxidase negative. A. calcoaceticus is a part of the A. calcoaceticus-A. baumannii complex together with Acinetobacter baumannii, Acinetobacter nosocomialis, Acinetobacter pitti and Acinetobacter seifertii.
Acinetobacter baumannii is a typically short, almost round, rod-shaped (coccobacillus) Gram-negative bacterium. It is named after the bacteriologist Paul Baumann. It can be an opportunistic pathogen in humans, affecting people with compromised immune systems, and is becoming increasingly important as a hospital-derived (nosocomial) infection. While other species of the genus Acinetobacter are often found in soil samples, it is almost exclusively isolated from hospital environments. Although occasionally it has been found in environmental soil and water samples, its natural habitat is still not known.
Cupriavidus metallidurans is a non-spore-forming, Gram-negative bacterium which is adapted to survive several forms of heavy metal stress.
Aerobic denitrification or co-respiration the simultaneous use of both oxygen (O2) and nitrate (NO3−) as oxidizing agents, performed by various genera of microorganisms. This process differs from anaerobic denitrification not only in its insensitivity to the presence of oxygen, but also in that it has a higher potential to create the harmful byproduct nitrous oxide.
Acinetobacter junii is a species of bacteria. Its type strain is ATCC 17908. It can be pathogenic. This bacterium has been linked to nosocomial infections including catheter-related blood stream infections and cellulitis.
Roseobacter litoralis is a species of aerobic pink-pigmented bacteria. It contains Bacteriochlorophyll a. It contains spheroidenone, does not synthesize bacteriochlorophyll anaerobically, but shows aerobic phototrophic activity. It is also considered a photosynthetic marine bacterium. Cells are ovoid or rod-shaped and motile by subpolar flagella. R. litoralis does not reduce nitrate, while R. dentrificans does. R. litoralis can be found in marine seaweed.
Azoarcus evansii is a species of bacteria. Its type strain is KB 740T.
Acinetobacter ursingii is a species of potentially pathogenic bacteria. Its type strain is LUH 3792T.
Acinetobacter schindleri is a species of bacteria. It is potentially pathogenic. Its type strain is LUH 5832T.
Desulfovibrio oxyclinae is a bacterium. It is sulfate-reducing, and was first isolated from the upper 3mm layer of a hypersaline cyanobacterial mat in Sinai.
Acinetobacter brisouii is a gram-negative, strictly aerobic, non-spore-forming, nonmotile bacterium from the genus Acinetobacter isolated from a peat layer on Yongneup in South Korea.
Acinetobacter nosocomialis is a gram-negative, strictly aerobic bacterium from the genus Acinetobacter isolated from a patient at MetroHealth in Cleveland, Ohio. Acinetobacter nosocomialis belongs to the Acinetobacter calcoaceticus-baumannii complex.
Acinetobacter pittii is a Gram-negative, oxidase-negative, catalase-positive, strictly aerobic, nonmotile, diplococcoid rod bacterium from the genus Acinetobacter. DNA-DNA hybridization studies have been used to identify DNA groups within the genus Acinetobacter and A. pittii belongs to the Acinetobacter calcoaceticus-baumannii complex. The specific epithet pittii is named after the British microbiologist Tyrone Pitt.
Acinetobacter soli is a Gram-negative, catalase-positive, oxidase-negative, strictly aerobic rod-shaped, nonmotile bacterium from the genus Acinetobacter isolated from forest soil at Mt. Baekwoon in the Republic of Korea. . Acinetobacter soli can cause bloodstream infection in neonates.
Erythrobacter litoralis is a species of bacterium. E. litoralis strain HTCC2594 was first sequenced in 2009. Erythrobacter litoralis strain DSM 8509 was developed as a comparative genetic model system to investigate the role of visible light in regulation of the general stress response in Alphaproteobacteria. The complete genome sequence of E. litoralis DSM 8509 has been published.
Thermoleophilum album is a bacterium obligate for thermophily and n-alkane substrates, the type species of its genus. It is Gram-negative, aerobic, small, and rod-shaped. It lacks pigmentation, motility, and the ability to form endospores, with type strain ATCC 35263.
