Caldicellulosiruptor is a genus of thermophilic, anaerobic, Gram-positive, non-spore forming bacteria. Originally placed within the highly polyphyletic class Clostridia, order Thermoanaerobacterales and family Thermoanaerobacterales Family III according to the NCBI and LPSN, it is now thought to lie outside of the Bacillota. Caldicellulosiruptor is known to degrade and ferment complex carbohydrates from plant matter, such as cellulose and hemicellulose (hence its name), and certain species in the genus have been identified as potential candidates for biofuel production.
The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) [1] and National Center for Biotechnology Information (NCBI) [2]

The Erysipelotrichaceae are a family of Gram-positive bacteria.
The Halanaerobiales are an order of bacteria placed within the class Clostridia, and encompassing two families, the Halanaerobiaceae and the Halobacteroidaceae. Originally placed within the highly polyphyletic class Clostridia, according to the NCBI and LPSN, it is now thought to lie outside the Bacillota. Halanaerobiales are halophilic obligate anaerobes with a fermentative or homoacetogenic metabolism.
The Thermoanaerobacterales is a polyphyletic order of bacteria placed within the polyphyletic class Clostridia, and encompassing four families: the Thermoanaerobacteraceae, the Thermodesulfobiaceae, the Thermoanaerobacterales Family III. Incertae Sedis, and the Thermoanaerobacterales Family IV. Incertae Sedis, and various unplaced genera.
Acidaminococcus is a genus in the phylum Bacillota (Bacteria), whose members are anaerobic diplococci that can use amino acids as the sole energy source for growth. Like other members of the class Negativicutes, they are gram-negative, despite being Bacillota, which are normally gram-positive.
Dehalogenimonas is a genus in the phylum Chloroflexota (Bacteria). Members of the genus Dehalogenimonas can be referred to as dehalogenimonads.
Pectinatus is a genus of Bacillota bacteria classified within the class Negativicutes.
Sporomusa is a genus of Bacillota bacteria classified within the class Negativicutes.
Megamonas is a genus of Bacillota bacteria classified within the class Negativicutes.
Megasphaera is a genus of Bacillota bacteria classified within the class Negativicutes.
Dialister is a genus of Bacillota bacteria classified within the class Negativicutes.
The Selenomonadales are an order of bacteria within the class Negativicutes; unlike most other members of Bacillota, they are Gram-negative. The phylogeny of this order was initially determined by 16S rRNA comparisons. More recently, molecular markers in the form of conserved signature indels (CSIs) have been found specific for all Selenomonadales species. On the basis of these markers, the Selenomonadales are inclusive of two distinct families, and are no longer the sole order within the Negativicutes. Several CSIs have also been found specific for both families, Sporomusaceae and Selenomonadceae. Samples of bacterial strains within this order have been isolated from the root canals of healthy human teeth.
Moorella is a genus of bacteria belonging to the phylum Bacillota.
Pelosinus is a genus of Bacillota bacteria classified within the class Negativicutes.
Halobellus is a genus of halophilic archaea.
Halorientalis is a genus of archaea in the family of Haloarculaceae.
Hydrogenobacter is a genus of bacteria, one of the few in the phylum Aquificota. Type species is H. thermophilus. This genus belongs to Bacteria as opposed to the other inhabitants of extreme environments, the Archaea.
Orenia is a genus of bacteria from the family of Halobacteroidaceae. Orenia bacteria occurs in saline environments.
Halanaerobium is a gram-negative, non-endospore-forming, rod-shaped, and strictly anaerobic genus of bacteria from the family Halanaerobiaceae.
The Thermodesulfobacteriaceae are a family of sulfate-reducing bacteria.
Tepidanaerobacteraceae is a family of Gram positive bacteria in the class Clostridia.
