Genera | |
The Alicyclobacillaceae are a family of Gram-positive bacteria. All members of this family are aerobic and form endospores. [2]
The family contains four genera: Alicyclobacillus , Effusibacillus , Kyrpidia , and Tumebacillus . [2] When originally created in 2009, Alicyclobacillaceae was a monophyletic family, only including genus Alicyclobacillus. In 2011, the novel genus Kyrpidia was proposed and placed in family Alicyclobacillaceae, and Tumebacillus was placed into the family as well. [3] In 2014, the novel genus Effusibacillus was proposed and added as the fourth member of Alicyclobacillaceae. [2]
Alicyclobacillus is the largest genus in Alicyclobacillaceae, with over 20 validly published species. The species are all acidophilic and have thermally resistant endospores. Many species are common soil organisms. Certain Alicyclobacillus species (especially A. acidoterrestris ) have been implicated in spoilage of pasteurized fruit juice. [4]
Effusibacillus contains three species (as of 2019). Members of this genus have been isolated from a lake in Japan, a lake in Antarctica, and from the blood of a woman. E. lacus and E. pohliae are both thermophiles, with optimum growth temperatures above 50 °C, while the optimum growth temperature for E. consociatus is 30 °C. [2] [5] [6]
Kyrpidia contains two species (as of 2019). Both species of Kyrpidia have been isolated from areas of high volcanic activity in Tuscany, Italy, and the Azores. The optimum temperature for growth for both members of the genus is approximately 55 °C. [7] [8]
Tumebacillus contains 8 species. Members of this genus have been isolated from arctic permafrost, soil samples, cassava wastewater, decomposing algal scum, river water, and the gut of a vulture. [9] Tumebacillus was found during surveys of nasal airways of infants, an underground subway in Norway, and a mountain observatory in Austria. [10] [11] [12]
No member of Alicyclobacillaceae has been found to be infectious. Effusibacillus consociatus was isolated from human blood and Tumebacillus was found during a survey of nasal airways of infants, but in neither instance were the bacteria found to be the cause of infection. [10] [6]
The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) [13] and National Center for Biotechnology Information (NCBI) [14]

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:
Thermus is a genus of thermophilic bacteria. It is one of several bacteria belonging to the Deinococcota phylum. Thermus species can be distinguished from other genera in the family Thermaceae as well as all other bacteria by the presence of eight conserved signature indels (CSIs) found in proteins such as adenylate kinase and replicative DNA helicase as well as 14 conserved signature proteins (CSPs) that are exclusively shared by members of this genus.
Alicyclobacillus is a genus of Gram-variable, rod-shaped, spore-forming bacteria. The bacteria are able to grow in acidic conditions, while the spores are able to survive typical pasteurization procedures.
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
Armatimonadota is a phylum of gram-negative bacteria.
Desulfosporosinus is a genus of strictly anaerobic, sulfate-reducing bacteria, often found in soil.
Laceyella is a Gram-positive, thermophilic, spore-forming and aerobic bacterial genus from the family of Thermoactinomycetaceae. The genus Laceyella is namened after the English microbiologist John Lacey.
Caldibacillus is a facultative anaerobe genus of bacteria that stains Gram-positive from the family of Bacillaceae. The type species of this genus is Caldibacillus debilis.
Alicyclobacillus contaminans is a species of Gram positive, strictly aerobic, bacterium. The bacteria are acidophilic and produce endospores. It was first isolated during a survey from both orange juice, and soil in Fuji City, Japan. The species was first described in 2007, and the name is derived from the Latin contaminans (contaminating).
Alicyclobacillus fastidiosus is a species of Gram positive, strictly aerobic, bacterium. The bacteria are acidophilic and produce endospores. It was first isolated from apple juice. The species was first described in 2007, and the name refers to the fastidious nature of the organism; the bacteria would start to die off after 7 days when plated on typical agar for isolating Alicyclobacillus. Additionally, the species produced fewer spores than other members of its genus, and took much longer to produce the spores.
Alicyclobacillus kakegawensis is a species of Gram positive, strictly aerobic, bacterium. The bacteria are acidophilic and produce endospores. It was first isolated from soil in Kakegawa, Japan. The species was first described in 2007, and the named after the city from which it was first isolated.
Alicyclobacillus macrosporangiidus is a species of Gram positive, strictly aerobic, bacterium. The bacteria are acidophilic and produce endospores. It was first isolated from soil in a crop field in Fujieda, Japan. The species was first described in 2007, and the name is derived from the Latin macros (big) and sporangium (sporangia), referring to the large spores produced by the organism.
Alicyclobacillus sacchari is a species of Gram positive, strictly aerobic, bacterium. The bacteria are acidophilic and produce endospores. It was first isolated from liquid sugar. The species was first described in 2007, and the name is derived from the Latin sacchari.
Alicyclobacillus shizuokensis is a species of Gram positive, strictly aerobic, bacterium. The bacteria are acidophilic and produce endospores. It was first isolated from soil in a crop field in Shizuoka, Japan. The species was first described in 2007, and the name refers to the city from which it was first isolated.
Alkalitalea is a genus of bacteria from the family of Blastocatellaceae.
Kyrpidia is a genus of Gram-positive, rod-shaped, thermophilic, spore-forming bacteria.
Kyrpidia tusciae is a species of Gram positive, facultatively anaerobic, thermophilic bacterium. The cells are rod-shaped and form spores.
Effusibacillus is a genus of Gram-positive, rod-shaped, aerobic, spore-forming bacteria.
Effusibacillus pohliae is a species of Gram positive, aerobic, thermophilic bacterium. The cells are rod-shaped and form spores. It was first isolated from Mount Melbourne, Antarctica. The species is named after the genus of Pohlia nutans, a species of moss that was colonizing the area where the type strain was isolated. E. pohliae has also been isolated from a geothermal heat pump in South Korea.
Rhodothermus is a genus of bacteria.
