Undibacterium is a genus of Gram-negative, oxidase- and catalase-positive Betaproteobacteria in the Oxalobacteraceae family. Undibacterium bacteria occurs in drinking water.
Undibacterium oligocarboniphilum is a Gram-negative, oxidase positive, catalase positive, flagellated, rod-shaped bacterium of the genus Undibacterium which was isolated from purified water. Its 16S rRNA gene sequence analysis has shown that it belongs to the family Oxalobacteraceae.
Undibacterium parvum is a Gram-negative, rod-shaped, oxidase positive, non-spore-forming, and low nutrient-loving bacterium of the genus Undibacterium and family Oxalobacteraceae which was found in drinking water.
Undibacterium pigrum is a Gram-negative, rod-shaped, oxidase positive, non-spore-forming, and nonmotile bacterium of the genus Undibacterium, which was found in drinking water.
The species of the genus Aquabacterium are motile, rod-shaped, Gram-negative, oxidase-positive, catalase-negative bacteria which were isolated from drinking water biofilms in Berlin. Identified species include Aquabacterium citratiphilum, Aquabacterium parvum, and Aquabacterium commune. Three bacterial strains isolated from biofilms of the Berlin drinking water system were characterized with respect to their morphological and physiological properties and their taxonomic position. Phenotypically, the bacteria investigated were motile, Gram-negative rods, oxidase-positive and catalase-negative, and contained polyalkanoates and polyphosphate as storage polymers. They displayed a microaerophilic growth behaviour and used oxygen and nitrate as electron acceptors, but not nitrite, chlorate, sulfate, or ferric iron. The substrates metabolized included a broad range of organic acids, but no carbohydrates at all. The three species can be distinguished from each other by their substrate use, ability to hydrolyse urea and casein, cellular protein patterns, and growth on nutrient-rich media, as well as their temperature, pH, and NaCl tolerances. Phylogenetic analysis, based on 16S rRNA gene sequence comparison, revealed that the isolates are affiliated to the beta 1-subclass of Proteobacteria. The isolates constitute three new species with internal levels of DNA relatedness ranging from 44.9 to 51.3%. It is proposed that a new genus, Aquabacterium gen. nov., should be created, including Aquabacterium citratiphilum sp. nov., Aquabacterium parvum sp. nov., and Aquabacterium commune sp. nov. The type species of the new genus is Aquabacterium commune.
Aquabacterium commune is a Gram-negative, catalase-negative bacterium of the genus Aquabacterium in the family Comamonadaceae, which was isolated with Aquabacterium citratiphilum and Aquabacterium parvum from biofilms of drinking water in Berlin. Aquabacterium commune has got a single polar flagellum and its colonies are transparent.
Aquabacterium fontiphilum is a Gram-negative non-spore-forming, motile bacterium of the genus Aquabacterium in the family Comamonadaceae, which was isolated from a water sample from the Nature Valley in Hsinchu County in Taiwan. Aquabacterium fontiphilum has a single polar flagellum and its colonies are semitransparent.
Aquabacterium parvum is a Gram-negative, oxidase-positive, catalase-negative bacterium of the genus Aquabacterium in the family Comamonadaceae which was isolated with Aquabacterium commune and Aquabacterium citratiphilum from biofilms of Berlins drinking water.
Curvibacter delicatus is a Gram-negative bacterium from the genus Curvibacter and family Comamonadaceae, which was isolated from well water.
Curvibacter gracilis is a Gram-negative bacterium from the genus Curvibacter and family Comamonadaceae, which was isolated from well 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.
Thiomonas arsenitoxydans is a Gram-negative, moderately acidophilic, non-spore-forming, rod-shaped, motile bacterium from the genus Thiomonas, which has the ability to use arsenite as an energy source by oxidizing it.
Streptomyces angustmyceticus is a bacterium species from the genus Streptomyces. Streptomyces angustmyceticus produces angustmycin.
