Thermotoga subterranea is a thermophilic, anaerobic, non-spore-forming, motile and Gram-negative bacterium, with type strain SL1. [1]
The Thermomicrobia is a group of thermophilic green non-sulfur bacteria. Based on species Thermomicrobium roseum and Sphaerobacter thermophilus, this bacteria class has the following description:
The Thermotogota are a phylum of the domain Bacteria. The phylum Thermotogota is composed of Gram-negative staining, anaerobic, and mostly thermophilic and hyperthermophilic bacteria.
Sulfur-reducing bacteria are microorganisms able to reduce elemental sulfur (S0) to hydrogen sulfide (H2S). These microbes use inorganic sulfur compounds as electron acceptors to sustain several activities such as respiration, conserving energy and growth, in absence of oxygen. The final product or these processes, sulfide, has a considerable influence on the chemistry of the environment and, in addition, is used as electron donor for a large variety of microbial metabolisms. Several types of bacteria and many non-methanogenic archaea can reduce sulfur. Microbial sulfur reduction was already shown in early studies, which highlighted the first proof of S0 reduction in a vibrioid bacterium from mud, with sulfur as electron acceptor and H2 as electron donor. The first pure cultured species of sulfur-reducing bacteria, Desulfuromonas acetoxidans, was discovered in 1976 and described by Pfennig Norbert and Biebel Hanno as an anaerobic sulfur-reducing and acetate-oxidizing bacterium, not able to reduce sulfate. Only few taxa are true sulfur-reducing bacteria, using sulfur reduction as the only or main catabolic reaction. Normally, they couple this reaction with the oxidation of acetate, succinate or other organic compounds. In general, sulfate-reducing bacteria are able to use both sulfate and elemental sulfur as electron acceptors. Thanks to its abundancy and thermodynamic stability, sulfate is the most studied electron acceptor for anaerobic respiration that involves sulfur compounds. Elemental sulfur, however, is very abundant and important, especially in deep-sea hydrothermal vents, hot springs and other extreme environments, making its isolation more difficult. Some bacteria – such as Proteus, Campylobacter, Pseudomonas and Salmonella – have the ability to reduce sulfur, but can also use oxygen and other terminal electron acceptors.
Thermotoga is a genus of the phylum Thermotogota. Members of Thermotoga are hyperthermophilic bacteria whose cell is wrapped in a unique sheath-like outer membrane, called a "toga".
Thermoanaerobacter is a genus in the phylum Bacillota (Bacteria). Members of this genus are thermophilic and anaerobic, several of them were previously described as Clostridium species and members of the now obsolete genera Acetogenium and Thermobacteroides
Thermotoga maritima is a hyperthermophilic, anaerobic organism that is a member of the order Thermotogales. It employs [FeFe]-hydrogenases to produce hydrogen gas (H2) by fermenting many different types of carbohydrates.
Chlorobaculum tepidum, previously known as 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.
Thermotoga neapolitana is a hyperthermophilic organism that is a member of the order Thermotogales.
Thermocrinis minervae is a bacterium. Its cells are gram-negative and are approximately 2.4–3.9 micrometres long and 0.5–0.6 micrometres wide; they are motile rods with polar flagella. It grows in temperatures between 65 °C (149 °F) and 85 °C (185 °F). Its type strain is CR11T.
Thermotoga hypogea is a hyperthermophilic organism that is a member of the order Thermotogales. It is thermophilic, xylanolytic, glucose-fermenting, strictly anaerobic and rod-shaped. The type strain of T. hypogea is SEBR 7054.
Luteimonas composti is a moderately thermophilic, yellow-pigmented bacterium. It is Gram-negative and rod-shaped, with type strain CC-YY255(T).
Thermotoga elfii is a rod-shaped, glucose-fermenting bacterium. The type strain of T. elfii is SEBR 6459T. The genus Thermotoga was originally thought to be strictly found surrounding submarine hydrothermal vents, but this organism was subsequently isolated in African oil wells in 1995. A protective outer sheath allows this microbe to be thermophilic. This organism cannot function in the presence of oxygen making it strictly anaerobic. Some research proposes that the thiosulfate-reducing qualities in this organism could lead to decreased bio-corrosion in oil equipment in industrial settings.
Thermotoga lettingae is a thermophilic, anaerobic, non-spore-forming, motile and Gram-negative bacterium, with type strain TMOT.
Thermotoga petrophila is a hyperthermophilic, anaerobic, non-spore-forming, rod-shaped fermentative heterotroph, with type strain RKU-1T.
Thermotoga naphthophila is a hyperthermophilic, anaerobic, non-spore-forming, rod-shaped fermentative heterotroph, with type strain RKU-10T.
Fervidobacterium gondwanense is a species of thermophilic anaerobic bacteria. It is non-sporulating, motile, gram-negative, and rod-shaped.
Fervidobacterium changbaicum is a species of thermophilic anaerobic bacteria. It is non-sporulating, motile, gram-negative, and rod-shaped. The type strain is CBS-1(T).
Thermococcus stetteri is an extremely thermophilic, marine, sulfur-metabolizing archaebacterium. It is anaerobic, its cells being irregular cocci 1 to 2 μm in diameter. Of the strains first isolated, two were motile due to a tuft of flagella, while the other two strains were nonmotile. Its type strain is K-3. It can grow on starch, pectin, and peptides, but not amino acids.
Desulfotomaculum geothermicum is a thermophilic, fatty acid-degrading, sulfate-reducing bacterium. Its cells are Gram-negative and form gas vacuoles during sporulation. Its type strain is BSD.
