Erythrobacter longus is a species of bacteria, the genus' type species. It contains bacteriochlorophyll a. It is motile by means of subpolar flagella. Its type strain is OCh101 (= IFO 14126). [1]
Aerobic anoxygenic phototrophic bacteria (AAPBs) are alphaproteobacteria and gammaproteobacteria that are obligate aerobes that capture energy from light by anoxygenic photosynthesis. Anoxygenic photosynthesis is the phototrophic process where light energy is captured and stored as ATP. The production of oxygen is non-existent and, therefore, water is not used as an electron donor. They are widely distributed marine plankton that may constitute over 10% of the open ocean microbial community. They can be particularly abundant in oligotrophic conditions where they were found to be 24% of the community. Aerobic anoxygenic phototrophic bacteria are photoheterotrophic (phototroph)microbes that exist in a variety of aquatic environments. Photoheterotrophs, are heterotrophic organisms that use light to produce energy, but are unable to utilize carbon dioxide as their primary carbon source. Most are obligately aerobic, meaning they require oxygen to grow. One remarkable aspect of these novel bacteria is that they, unlike other similar bacteria, are unable to utilize BChl (bacteriochlorophyll) for anaerobic growth. The only photosynthetic pigment that exists in AAPB is BChl a. Anaerobic phototrophic bacteria, on the contrary, can contain numerous species of photosynthetic pigments like bacteriochlorophyll a, b, c, d, e, f, etc. There is still a large void in the areas regarding the abundance and genetic diversity of the AAPB, as well as the environmental variables that regulate these properties.
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.
Rhodoblastus acidophilus, formerly known as Rhodopseudomonas acidophila, is a gram-negative purple non-sulfur bacteria. The cells are rod-shaped or ovoid, 1.0 to 1.3 μm wide and 2 to 5 μm long. They are motile by means of polar flagella, and they multiply by budding. The photopigments consist of bacteriochlorophyll a and carotenoids of the spirilloxanthin series. All strains can grow either under anaerobic conditions in the light or under microaerophilic to aerobic conditions in the dark.
Desulfuromonas acetoxidans is a species of bacteria. It is strictly anaerobic, rod-shaped, laterally flagellated and Gram-negative. It is unable to ferment organic substances; it obtains energy for growth by anaerobic sulfur respiration.
Chlorobium tepidum is an anaerobic, thermophilic green sulfur bacteria first isolated from New Zealand. Cells are gram-negative and non-motile rods of variable length. They contain bacteriochlorophyll c and chlorosomes.
Roseiflexus castenholzii is a thermophilic, filamentous, photosynthetic bacterium that lacks chlorosomes.
Synergistes jonesii is a species of bacteria, the type species of its genus. It is a rumen bacterium that degrades toxic pyridinediols including mimosine. It is obligately anaerobic, gram-negative and rod-shaped.
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.
Roseococcus thiosulfatophilus is a species of bacterium, the type species of its genus.
Erythromicrobium ramosum is a species of bacterium, the type species of its genus.
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.
Actinopolyspora halophila is a bacterium. It differs from its cogenerate bacteria in the make-up of its cell wall. Like all Actinopolyspora, A. halophila requires saline conditions for survival, however wild types generally require more than 12% salt concentration to grow, and can grow in concentrations of up to 30%.
Pectinatus frisingensis is a species of anaerobic, Gram-negative, rod-shaped bacteria first isolated from spoilt beer.
Heliothrix oregonensis is a phototrophic filamentous, gliding bacterium containing bacteriochlorophyll a that is aerotolerant and photoheterotrophic.
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.
Chloroflexus aggregans is a thermophilic, filamentous, phototrophic bacterium that forms dense cell aggregates. Its type strain is strain MD-66.
Thiorhodovibrio winogradskyi is a purple sulfur bacteria, the type species of its genus. Its cells are vibrioid-to spirilloid-shaped and motile by means of single polar flagella. It is moderately halophilic, with type strain SSP1.
Roseivivax halotolerans is a species of bacteria. It is aerobic and bacteriochlorophyll-containing, first isolated from the epiphytes on the stromatolites of a saline lake located on the west coast of Australia. It is chemoheterotrophic, Gram-negative, motile, rod-shaped and with subpolar flagella. Its type strain is OCh 210T.
