Biology:Auribacterota
Auribacterota is a candidate bacterial phylum of uncultured anaerobes first found in gold mine fluids. The name comes from Latin aurum (gold). It is known only from metagenomes.[1][2]
These bacteria are strict fermenters. They eat sugars and amino acids, and make H2 and H2S. No oxygen is used. Some of these bacteria have gas vesicles or pili.[2]
The bacteria live in anoxic water columns, sediments, and subsurface. They are common in Ace Lake, Antarctica (up to 4% of microbes).[2] They help break down dead stuff and cycle sulfur.[3]
There are four candidate classes. Type species: "Candidatus Auribacter fodinae".
Phylogeny
The phylum Auribacterota is not validly published and remains a candidate phylum. It was proposed by Williams et al. (2022) based on metagenome-assembled genomes (MAGs) from Ace Lake, a meromictic lake in Antarctica. The taxonomy includes four candidate classes, each containing novel genera and species identified from high-quality MAGs. Phylogenetic analyses place Auribacterota among the "microbial dark matter" phyla, distinct from well-characterized bacterial lineages.
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).[4]
