Alicyclobacillus cycloheptanicus is a species of Gram positive, strictly aerobic, bacterium. The bacteria are acidophilic and produce endospores. It was first isolated from soil. The species was originally classified as Bacillus cycloheptanicus in 1987, but further 16S rRNA studies found that the species belonged in the newly created genus Alicyclobacillus. The species name refers ω-cycloheptane fatty acids in the cell membrane.
Alicyclobacillus acidocaldarius is a species of Gram positive, strictly aerobic, bacterium. The bacteria are acidophilic, thermophilic, and produce endospores. The first identified strains of A. acidocaldarius were from geysers in Yellowstone National Park and fumerole soil in Hawaii Volcano National Park. The species was originally classified as Bacillus acidocaldarius in 1971, but further 16S rRNA studies found that the species belonged in the newly created genus Alicyclobacillus. The species name is derived from the Latin acidum (acid) and caldarius, referring to the acidic and high temperature environments from which it was first isolated. Thomas D. Brock was one of the researchers who first categorized the species; his discovery of Thermus aquaticus allowed for other researchers to discover Taq polymerase and polyermase chain reaction (PCR).
Alicyclobacillus dauci is a species of Gram positive, strictly aerobic, bacterium. The bacteria are acidophilic and produced endospores. It was first isolated from spoiled mixed vegetable and fruit juice. The species was first described in 2015, and the name is derived from the Latin dauci.
Alicyclobacillus disulfidooxidans a species of Gram positive, strictly aerobic, bacterium. The bacteria are acidophilic and produced endospores. It was first isolated from waterwater sludge in Blake Lake City, Quebec, Canada. The species was first identified in 1996, but was classified as Sulfobacillus disulfidooxidansis. It was reclassified as Alicyclobacillus in 2005. The name is derived from the Latin duplus (double), sulfur (sulfur), and oxido (oxidize), referring to the bacterium's ability to oxidize disulfide.
Alicyclobacillus tolerans is a species of Gram positive, strictly aerobic, bacterium. The bacteria are acidophilic and produced endospores. It was first isolated from oxidizable lead–zinc ores in Uzbekistan. The strain was first identified in 1983, but was classified as Sulfobacillus thermosulfidooxidans subsp. thermotolerans strain K1. It was reclassified as Alicyclobacillus in 2005. The species name refers to the ability to tolerate changes in temperature and pH.
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.
Alicyclobacillus fodiniaquatilis is a species of Gram positive, strictly aerobic, bacterium. The bacteria are acidophilic and produced endospores. It was first isolated from acid mine water from a copper mine in Fujian Province, Republic of China. The species was first described in 2015, and the name is derived from Latin fodina (mine) and aqua water, referring to the original isolation location.
Alicyclobacillus herbarius is a species of Gram positive, strictly aerobic, bacterium. The bacteria are acidophilic and produced endospores. It was first isolated from a hibiscus-based herbal tea. The species was first described in 2002, and the name refers to the herbal tea from which it was first isolated.
Alicyclobacillus pomorum is a species of Gram positive, strictly aerobic, bacterium. The bacteria are acidophilic and produced endospores. It was first isolated from spoiled mixed fruit juice (containing fresh orange, apple, mango, pineapple, and raspberry juice). The species was first described in 2003, and the name is derived from Latin pomorum.
