Anaerolineaceae

Anaerolineaceae is a family of bacteria from the order of Anaerolineales.^[1][4][5][6] Anaerolineaceae bacteria occur in marine sediments.^[7] There are a total of twelve genera in this family, most of which only encompass one species.^[8] All known members of the family are Gram-negative and non-motile. They also do not form bacterial spores and are either mesophilic or thermophilic obligate anaerobes. It is also known that all species in this family are chemoheterotrophs.^[9]

History

The first species discovered in the family Anaerolineaceae was the species Anaerolinea thermophila, with a report on the matter written by Yuji Sekiguchi et. al. in 2003.^[10] It was isolated alongside the bacterial species Caldilinea aerophila, a facultative anaerobe. The discovery of these two specimens prompted the addition of a new subphylum in bacterial taxonomy.^[10]

Phylogeny

The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN)^[2] and National Center for Biotechnology Information (NCBI).^[11]
