Acidobacteria are a newly devised phylum of Bacteria, whose members are physiologically diverse and ubiquitous, especially in soils, but are under-represented in culture.^[1][2][3]

Members of this phylum are physiologically diverse, some being acidophilic, and were first recognized as a novel division in 1997.^[4] The first species, Acidobacterium capsulatum, of this phylum was discovered in 1991.^[5] Other notable species are Holophaga foetida,^[6] Geothrix fermentans,^[7] Acanthopleuribacter pedis^[8] and Bryobacter aggregatus.^[9] Since they have only recently been discovered and the large majority have not been cultured, the ecology and metabolism of these bacteria is not well understood.^[2] However, these bacteria may be an important contributor to ecosystems, since they are particularly abundant within soils.^[10]

As well as their natural soil habitat, unclassified group II Acidobacteria have also been identified as a contaminant of DNA extraction kit reagents, which may lead to their erroneous appearance in microbiota or metagenomic datasets.^[11]

Phylogeny

The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) ^{[12] [13]} and the phylogeny is based on 16S rRNA-based LTP release 111 by The All-Species Living Tree Project ^[14]

Notes:
♠ Strains found at the National Center for Biotechnology Information (NCBI) but not listed in the List of Prokaryotic names with Standing in Nomenclature (LSPN)
