Auribacterota is a candidatebacterialphylum of unculturedanaerobes first found in gold mine fluids. The name comes from Latinaurum (gold). It is known only frommetagenomes.[1][2]
These bacteria are strict fermenters. They eatsugars andamino acids, and make H2 and H2S. No oxygen is used. Some of these bacteria have gasvesicles or pili.[2]
The bacteria live in anoxic water columns, sediments, and subsurface. They are common inAce Lake,Antarctica (up to 4% of microbes).[2] They help break down dead stuff and cyclesulfur.[3]
There are four candidate classes. Type species: "Candidatus Auribacter fodinae".
The phylumAuribacterota is not validly published and remains acandidate phylum. It was proposed by Williamset al. (2022) based on metagenome-assembled genomes (MAGs) from Ace Lake, ameromictic lake in Antarctica. The taxonomy includes four candidate classes, each containing novel genera and species identified from high-quality MAGs:
Additional genera from Ace Lake include "Candidatus Euphemobacter frigidus" and "Candidatus Theseobacter exili". Phylogenetic analyses placeAuribacterota among the "microbial dark matter" phyla, distinct from well-characterized bacterial lineages.
