Archaeoglobaceae are a family of the Archaeoglobales. All known genera within the Archaeoglobaceae are hyperthermophilic and can be found near undersea hydrothermal vents. Archaeoglobaceae are the only family in the order Archaeoglobales, which is the only order in the class Archaeoglobi.
In the taxonomy of microorganisms, the Methanomicrobia are a class of the Euryarchaeota.
The Nitrobacteraceae are a family of gram-negative, aerobic bacteria. They include plant-associated bacteria such as Bradyrhizobium, a genus of rhizobia associated with some legumes. It also contains animal-associated bacteria such as Afipia felis, formerly thought to cause cat-scratch disease. Others are free-living, such as Rhodopseudomonas, a purple bacterium found in marine water and soils. The strain Rhodopseudomonas palustris DX-1 can generate an electric current with no hydrogen production, a trait being explored in the development of the microbial fuel cell. The genus Afipia has also been found in the atmosphere, where it uses methylsulfonylmethane as a carbon source.
Rhodopseudomonas palustris is a rod-shaped, Gram-negative purple nonsulfur bacterium, notable for its ability to switch between four different modes of metabolism.
Rhodopseudomonas is a genus of bacteria from the family Nitrobacteraceae.
Afifella is a genus in the phylum Pseudomonadota (Bacteria). Afifella are found in marine and estuarine settings, including microbial mats. They are anaerobes, with one cultured representative capable of photosynthesis.
A polar organelle is a structure at a specialised region of the bacterial polar membrane that is associated with the flagellar apparatus. This flagellum-associated structure can easily be distinguished from the other membrane regions in ultrathin sections of embedded bacteria by electron microscopy when the cell membrane is orientated perpendicular to the viewing direction. There, the membrane appears slightly thickened with a finely frilled layer facing the inside of the cell. It is also possible to isolate these polar organelles from the bacterial cells and study them in face view in negatively stained preparations.
Neurosporene is a carotenoid pigment. It is an intermediate in the biosynthesis of lycopene and a variety of bacterial carotenoids.
Rhodopin (1,2-dihydro-ψ,ψ-caroten-1-ol) is a carotenoid. It is a major carotenoid of phototropic bacteria such as Rhodomicrobium vannielii and Rhodopseudomonas acidophila strain 7050.
Rhodovulum sulfidophilum is a purple bacteria. The cells are rod-shaped, 0.6 to 0.9 μ wide and 0.9 to 2.0 μ long, and motile by means of polar flagella. Cell division occurs by binary fission. Its pigments consist of bacteriochlorophyll a and of carotenoids, most probably of the spheroidene group. The new species needs 2.5% (w/v) sodium chloride for optimal growth. The bacteria has a high sulfide tolerance. Sulfide and thiosulfate are oxidized to sulfate without an intermediate accumulation of elemental sulfur. It can either grow photoautotrophically or photoheterotrophically.
Rhodopila globiformis is a species of bacteria, formerly known as Rhodopseudomonas globiformis. It is a motile, spherical organism. Cells can grow between 1.6 and 1.8 μm in diameter. The photopigments consist of bacteriochlorophyll aP and aliphatic methoxylated ketocarotenoids. The organism grows under anaerobic conditions in the light or under microaerophilic conditions in the dark. Biotin, p-aminobenzoic acid and a source of reduced sulfur are required as growth factors in order to cultivate this bacteria. This bacteria possesses a high potential cytochrome c2.
Rhodoplanes elegans is a phototrophic purple nonsulfur bacteria with rod-shaped cells.
Rhodopseudomonas faecalis is a gram-negative, anaerobic, phototroph bacteria from the genus of Rhodopseudomonas with a polar flagella which was isolated from chicken faeces.
Rhodopseudomonas harwoodiae is a bacterium from the genus of Rhodopseudomonas.
Rhodomicrobium vannielii is a Gram-negative, purple non-sulfur, motile, thermophilic photoheterotroph bacterium. Phototrophic bacteria are ubiquitous and have been reportedly found in many marine and terrestrial ecosystems. Additionally, they can use light as an energy source and carbon dioxide as a carbon source. Considering this, R. vannielii is thought to have potential application in anaerobic treatment and bioremediation under high temperature conditions as the bacteria was isolated from water samples from a hot spring in Gadek, Malacca, Malaysia using glutamate-malate medium (GMM) and Pfennig's M2 medium. R. vannielii produces acyclic and aliphatic cyclic carotenoids like anhydrorhodovibrin, rhodovibrin, spirilloxanthin and rhodopin.
Rhodoplanes is a phototrophic genus of bacteria. Rhodoplanes produces hopanoids like diplopterol, tetrahymanol, 2-methyldiplopterol, 2-methyltetrahymanol, bacteriohopanetetrol, bacteriohopaneaminotriol and carotenoids like spirilloxanthin, rhodopin, anhydrorhodovibrin, 1,1′-dihydroxylycopene and 3,4,3′,4′-tetrahydrospirilloxanthin
Rhodoplanes roseus is a phototrophic bacterium from the genus of Rhodoplanes which has been isolated from a duck pond in Cambridge in New Zealand.
Rhodopseudomonas parapalustris is a rod-shaped, budding phototrophic and motile bacterium from the genus of Rhodopseudomonas which has been isolated from soil and freshwater sediments in India.
Julia Shalett Vinograd was a poet. She is well known as "The Bubble Lady" to the Telegraph Avenue community of Berkeley, California, a moniker she gained from blowing bubbles at the People's Park demonstrations in 1969. Vinograd is depicted blowing bubbles in the People's Park Mural off of Telegraph Avenue in Berkeley.
The Propionibacteriales are an order of bacteria.
