Thermicanus aegyptius is a microaerophile and thermophilic bacterium from the genus Thermicanus , which has been isolated from oxic soil in Egypt. [1] [3] [4] [5] [6]
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:
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 H
2 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.
In taxonomy, Methanomethylovorans is a genus of microorganisms with the family Methanosarcinaceae. This genus was first described in 1999. The species within it generally live in freshwater environments, including rice paddies, freshwater sediments and contaminated soil. They produce methane from methanol, methylamines, dimethyl sulfide and methanethiol. With the exception of M. thermophila, which has an optimal growth temperature of 50 °C, these species are mesophiles and do not tend to grow at temperatures above 40 °C.
Bacterial phyla constitute the major lineages of the domain Bacteria. While the exact definition of a bacterial phylum is debated, a popular definition is that a bacterial phylum is a monophyletic lineage of bacteria whose 16S rRNA genes share a pairwise sequence identity of ~75% or less with those of the members of other bacterial phyla.
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
Thermoanaerobacter acetoethylicus, formerly called Thermobacteroides acetoethylicus, is a species of thermophilic, nonspore-forming bacteria.
Coprothermobacter proteolyticus, formerly Thermobacteroides proteolyticus, is a thermophilic, non-spore-forming bacteria.
Acidobacterium capsulatum is a bacterium. It is an acidophilic chemoorganotrophic bacterium containing menaquinone. It is gram-negative, facultative anaerobic, mesophilic, non-spore-forming, capsulated, saccharolytic and rod-shaped. It is also motile by peritrichous flagella. Its type strain is JCM 7670.
Dechloromonas denitrificans is a gram negative, N2O-producing motile bacterium with a polar flagellum from the genus of Dechloromonas which was isolated from the earthworm Aporrectodea caliginosa. Colonies of Dechloromonas denitrificans are yellowish colored.
Acidiphilium cryptum is a species of heterotrophic bacteria, the type species of its genus. It is gram-negative, aerobic, mesophilic and rod-shaped. It does not form endospores and some cells are motile by means of one polar flagellum or two lateral flagella Lhet2 is the type strain.
Thermotoga lettingae is a thermophilic, anaerobic, non-spore-forming, motile and Gram-negative bacterium, with type strain TMOT.
Gordonia is a genus of gram-positive, aerobic, catalase-positive bacterium in the Actinomycetota, closely related to the Rhodococcus, Mycobacterium, and Nocardia genera. It is from the same lineage that includes Mycobacterium tuberculosis. The genus was discovered by Tsukamura in 1971 and named after American bacteriologist Ruth Gordon.. Many species are often found in the soil and are rarely known to cause infections in humans. Some investigations have found that 28 °C is the ideal temperature for the growth of Gordonia bacteria. Some species of Gordonia, such as Gordonia rubripertincta, produce colonies that have a bright orange or orange-red color.
Roseivivax halodurans is a species of bacteria, the type species of its genus. It is aerobic and bacteriochlorophyll-containing, first isolated from the charophytes 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 239T.
Tepidibacter is a genus of Gram-positive bacteria in the family Clostridiaceae.
Thermicanus is a genus of bacteria from the order Bacillales. Up to now, only one species of this genus is known.
Lactovum is a genus of bacteria within the family Streptococcaceae. The genus contains a single species, Lactovum miscens, an aerotolerant, anaerobic species originally isolated from soil from the Stiegerwald forest in Germany.
Clostridium acidisoli is a nitrogen-fixing bacterium from the genus of Clostridium which has been isolated from acidic peat bog soil from the Fichtel Mountains in Germany.
Clostridium akagii is a nitrogen-fixing and anaerobic bacterium from the genus Clostridium which has been isolated from the Fichtel Mountains in Germany.
Caloranaerobacter is a Gram-negative, thermophilic, anaerobic and chemoorganotrophic bacterial genus from the family of Clostridiaceae.
Albidovulum inexpectatum is a thermophilic and strictly aerobic bacteria from the genus of Albidovulum which has been isolated from a marine hot spring from the Island of San Miquel.
