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. [1] Like other members of the class Negativicutes, they are gram-negative, despite being Bacillota, which are normally gram-positive.
The name Acidaminococcus derives from:
Neo-Latin noun acidum (from Latin adjective acidus, sour), an acid; Neo-Latin adjective aminus, amino; Neo-Latin masculine gender noun coccus (from Greek masculine gender noun kokkos (κόκκος), grain, seed), coccus-shaped; Neo-Latin masculine gender noun Acidaminococcus, the amino acid coccus. [1]
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 Bacillota are a phylum of bacteria, most of which have gram-positive cell wall structure. The renaming of phyla such as Firmicutes in 2021 remains controversial among microbiologists, many of whom continue to use the earlier names of long standing in the literature.
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.
Cystobacter is a genus in the phylum Myxococcota (Bacteria).
Acetomicrobium is a genus in the phylum Synergistota (Bacteria). In 2016, the former genus Anaerobaculum was folded into Acetomicrobium.
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
Acrocarpospora is a genus of bacteria in the phylum Actinomycetota. The major respiratory quinone is menaquinone MK-9(H ) and use madurose, an actinomycete whole-cell sugar.
Actinoallomurus is a genus in the phylum Actinomycetota (Bacteria).
Actinocatenispora is a genus in the phylum Actinomycetota (Bacteria).
Actinocorallia is a genus in the phylum Actinomycetota (Bacteria).
Actinopolymorpha is a genus in the phylum Actinomycetota (Bacteria).
Actinospica is a genus in the phylum Actinomycetota (Bacteria).
Deferribacter is a genus in the phylum Deferribacterota (Bacteria).
Dehalogenimonas is a genus in the phylum Chloroflexota (Bacteria). Members of the genus Dehalogenimonas can be referred to as dehalogenimonads.
Akkermansia is a genus in the phylum Verrucomicrobiota (Bacteria). The genus was first proposed by Derrien et al. (2004), with the type species Akkermansia muciniphila.
Cryptosporangium is a genus of bacteria in the phylum Actinomycetota.
Kineococcus is an Actinomycete genus within the family Kineosporiaceae.
Stigmatella is a bacterium genus in the phylum Myxococcota.
The Erysipelotrichia are a class of bacteria of the phylum Bacillota. Species of this class are known to be common in the gut microbiome, as they have been isolated from swine manure and increase in composition of the mouse gut microbiome for mice switched to diets high in fat.
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.
Marinactinospora is a genus in the phylum Actinomycetota (Bacteria). It contains a single species, Marinactinospora thermotolerans. The species has a high tolerance for environmental temperatures, up to 55°C.
