Desulfofrigus fragile is a bacterium. [1] It is a psychrophilic Gram-negative and sulfate-reducing bacteria with type strain Lsv21T.
The Desulfobacteraceae are a family of Thermodesulfobacteriota. They reduce sulfates to sulfides to obtain energy and are strictly anaerobic. They have a respiratory and fermentative type of metabolism. Some species are chemolithotrophic and use inorganic materials to obtain energy and use hydrogen as their electron donor.
Desulfobacter hydrogenophilus is a strictly anaerobic sulfate-reducing bacterium. It was isolated and characterized in 1987 by Friedrich Widdel of the University of Konstanz (Germany). Like most sulfate-reducing bacteria (SRB), D. hydrogenophilus is capable of completely oxidizing organic compounds (specifically acetate, pyruvate and ethanol) to CO2, and therefore plays a key role in biomineralization in anaerobic marine environments. However, unlike many SRB, D. hydrogenophilus is a facultative lithoautotroph, and can grow using H2 as an electron donor and CO2 as a carbon source. D. hydrogenophilus is also unique because it is psychrophilic (and has been shown to grow at temperatures as low as 0 °C or 32 °F). It is also diazotrophic, or capable of fixing nitrogen.
Desulfosporosinus is a genus of strictly anaerobic, sulfate-reducing bacteria, often found in soil.
Desulfofrigus oceanense is a bacterium. It is a psychrophilic Gram-negative and sulfate-reducing bacteria with type strain Asv26T.
Desulfuromusa ferrireducens is a species of psychrophilic, Fe(III)-reducing bacteria. It is Gram-negative, rod-shaped and motile. Its type strain is 102T.
Arthrobacter flavus is a species of psychrophilic bacteria. It is aerobic, gram-positive, non-spore-forming, non-motile, exhibits a rod-coccus growth cycle and produces a yellow pigment. Its type strain is CMS 19YT.
Psychroserpens burtonensis is a species of psychrophilic, yellow-pigmented bacteria. It is non-motile and nutritionally fastidious. Its type strain is ACAM 188.
Gelidibacter algens is a species of psychrophilic, yellow-pigmented bacteria. It is saccharolytic, exhibits rapid gliding motility, and its cells are rod-like to filamentous. Its type strain is ACAM 536.
Thermodesulforhabdus norvegica is a species of thermophilic sulfate-reducing bacteria, the type and only species of its genus. It is gram-negative, acetate-oxidizing, with type strain A8444.
Desulfovibrio bastinii is a moderately halophilic bacteria. It is sulfate-reducing, mesophilic and motile. Its type strain is SRL4225T.
Desulfovibrio gracilis is a moderately halophilic bacteria. It is sulfate-reducing, mesophilic and motile. Its type strain is SRL6146T.
Psychrobacter is a genus of Gram-negative, osmotolerant, oxidase-positive, psychrophilic or psychrotolerant, aerobic bacteria which belong to the family Moraxellaceae and the class Gammaproteobacteria. The shape is typically cocci or coccobacilli. Some of those bacteria were isolated from humans and can cause humans infections such as endocarditis and peritonitis. This genus of bacteria is able to grow at temperatures between −10 and 42 °C. Rudi Rossau found through DNA-rRNA hybridization analysis that Psychrobacter belongs to the Moraxellaceae. The first species was described by Juni and Heym. Psychrobacter occur in wide range of moist, cold saline habitats, but they also occur in warm and slightly saline habitats.
Gracilibacillus halotolerans is a Gram-positive, extremely halotolerant bacteria, the type species of its genus. Its type strain is NNT.
Glaciecola punicea is a psychrophilic bacteria found in Antarctic sea-ice habitats, being the type species of its genus. It is pigmented, psychrophilic, and a strictly aerobic chemoheterotroph. Its type strain is. Its genome has been sequenced.
Glaciecola pallidula is a psychrophilic bacteria found in Antarctic sea-ice habitats, being the type species of its genus. It is pigmented, psychrophilic, and a strictly aerobic chemoheterotroph. Its type strain is.
Desulfacinum infernum is a thermophilic sulfate-reducing bacterium, the type species of its genus. Its cells are oval, 1.5 by 2.5-3μm, non-motile and gram-negative.
Desulfofaba is a Gram-negative, anaerobic, non-spore-forming and motile bacteria genus from the family of Desulfobacteraceae.
Desulfofrigus is a Gram-negative, strictly anaerobic and non-spore-forming bacteria genus from the family of Desulfobacteraceae.
