Acidobacteria is a phylum of bacteria. Its members are physiologically diverse and ubiquitous, especially in soils, but are under-represented in culture.
The Burkholderiales are an order of Proteobacteria. Like all Proteobacteria, they are Gram-negative. They include several pathogenic bacteria, including species of Burkholderia, Bordetella, and Ralstonia. They also include Oxalobacter and related genera, which are unusual in using oxalic acid as their source of carbon. Other well-studied genera include Alcaligenes, Cupriavidus, Achromobacter, Comamonas, Delftia, Massilia, Duganella, Janthinobacterium, Polynucleobacter, non-pathogenic Paraburkholderia, Caballeronia, Polaromonas, Thiomonas, Collimonas, Hydrogenophaga, Sphaerotilus, Variovorax, Acidovorax, Rubrivivax and Rhodoferax, and Herbaspirillum.
Myriophyllum aquaticum is a flowering plant, a vascular dicot, commonly called parrot's-feather and parrot feather watermilfoil.
Eriocaulon is a genus of about 400 species commonly known as pipeworts, of monocotyledonous flowering plants in the family Eriocaulaceae. The genus is widely distributed, with the centers of diversity for the group occurring in tropical regions, particularly southern Asia and the Americas. A few species extend to temperate regions, with ca. 10 species in the United States, mostly in the southern states from California to Florida, and only two species in Canada; China has 35 species, also mostly southern. Only one species occurs in Europe, where it is confined to the Atlantic Ocean coasts of Scotland and Ireland; this species also occurs in eastern North America and is thought to be a relatively recent natural colonist in Europe. In the Americas, Eriocaulon is the only genus in its family that occurs north of Florida. They tend to be associated with wet soils, many growing in shallow water, in wetlands, or in wet savannas like flatwoods. In wet soils, their abundance appears to be related to water levels, fire frequency, and competition from other plants such as grasses. Experiments have shown that they are weak competitors compared to many other wetland plant species. Some species can persist as buried seeds during unfavorable conditions. The scientific name is derived from Ancient Greek εριον, erion, meaning 'wool', and καυλός, caulos, meaning 'stalk'.
Cronobacter is a genus of Gram-negative, facultatively anaerobic, oxidase-negative, catalase-positive, rod-shaped bacteria of the family Enterobacteriaceae. They are generally motile, reduce nitrate, use citrate, hydrolyze esculin and arginine, and are positive for L-ornithine decarboxylation. Acid is produced from D-glucose, D-sucrose, D-raffinose, D-melibiose, D-cellobiose, D-mannitol, D-mannose, L-rhamnose, L-arabinose, D-trehalose, galacturonate and D-maltose. Cronobacter spp. are also generally positive for acetoin production and negative for the methyl red test, indicating 2,3-butanediol rather than mixed acid fermentation. The type species of the genus Cronobacter is Cronobacter sakazakii comb. nov.
The Chloroflexi or Chlorobacteria are a phylum of bacteria containing isolates with a diversity of phenotypes, including members that are aerobic thermophiles, which use oxygen and grow well in high temperatures; anoxygenic phototrophs, which use light for photosynthesis ; and anaerobic halorespirers, which uses halogenated organics as electron acceptors.
Orontium aquaticum, sometimes called golden-club, floating arum, never-wets or tawkin, is a species of flowering plants in the family Araceae. It is the single living species in the genus Orontium, which also contains several extinct species described from fossils. O. aquaticum is endemic to the eastern United States and is found growing in ponds, streams, and shallow lakes. It prefers an acidic environment. The leaves are pointed and oval with a water repellent surface. The inflorescence is most notable for having an extremely small almost indistinguishable sheath surrounding the spadix. Very early in the flowering this green sheath withers away leaving only the spadix.
Janthinobacterium lividum is an aerobic, Gram-negative, soil-dwelling bacterium that has a distinctive dark-violet color, due to a compound called violacein, which is produced when glycerol is metabolized as a carbon source. Violacein has antibacterial, antiviral, and antifungal properties. Its antifungal properties are of particular interest, since J. lividum is found on the skin of certain amphibians, including the red-backed salamander, where it prevents infection by the devastating chytrid fungus.
Orontium, sometimes called golden-club, is a genus of flowering plants in the family Araceae. The single living species in the genus is Orontium aquaticum, while the two other described species, Orontium mackii and Orontium wolfei, are known from fossils.
Herbaspirillum aquaticum is a bacterium of the genus Herbaspirillum.
Janthinobacterium agaricidamnosum is a bacterium of the family Oxalobacteraceae and the genus Janthinobacterium that causes a soft rot disease of Agaricus bisporus. Because of this ability, it could help treating diseases caused by fungi in humans. Analyses have shown that jagaricin, a substance which is produced by J. agaricidamnosum, could have a major part for its antimycotic activity.
Exiguobacterium is a genus of bacilli and a member of the low GC phyla of Firmicutes. Collins et al. first described the genus Exiguobacterium with the characterization of E. aurantiacum strain DSM6208T from an alkaline potato processing plant. It has been found in areas covering a wide range of temperatures (-12 °C—55 °C) including glaciers in Greenland and hot springs in Yellowstone, and has been isolated from ancient permafrost in Siberia. This ability to survive in varying temperature extremes makes them an important area of study. Some strains in addition to dynamic thermal adaption are also halotolerant, can grow within a wide range of pH values (5-11), tolerate high levels of UV radiation, and heavy metal stress.
Methylobacterium aquaticum is a bacterium from the genus of Methylobacterium which has been isolated from drinking water in Seville in Spain.
Methylobacterium hispanicum is a bacterium from the genus of Methylobacterium which has been isolated from drinking water in Seville in Spain.
Chryseobacterium aquaticum is a Gram-negative, non-spore-forming and non-motile bacteria from the genus of Chryseobacterium.
Novosphingobium aquaticum is a Gram-negative, rod-shaped, strictly aerobic and non-motile bacterium from the genus of Novosphingobium which has been isolated from lake water in Suwon in Korea.
Brachybacterium is a genus of Gram positive, nonmotile bacteria. The cells are coccoid during the stationary phase, and irregular rods during the exponential phase. The genus name comes from Greek word brachy, meaning short, and Latin bacterium, meaning rods, referencing the short rods noted during the exponential phase.
Brachybacterium aquaticum is a species of Gram positive, strictly aerobic, pale yellow-pigmented bacterium. The cells are coccoid during the stationary phase, and irregular rods during the exponential phase. It was first isolated from a seawater sample collected from the coastal region of Kovalam, India off the Indian Ocean. The name is derived from Latin aquaticum.
Flavobacterium aquaticum is a Gram-negative bacterium from the genus of Flavobacterium which has been isolated from water from a rice field from Jamdih in India.
Phenylobacterium aquaticum is a Gram negative, strictly aerobic, non-spore-forming and non-motile bacterium from the genus of Phenylobacterium which has been isolated from a reservoir of a water purifier.
