Acidiphilium is a genus in the phylum Pseudomonadota (Bacteria). As the name suggests, this comprises a nutritionally diverse genus of bacteria adapted to life in extremely acidic conditions, and often exhibiting Fe(III) (ferric iron) reduction.
Etymology The name Acidiphilium derives from:Neo-Latin noun acidum (from Latin adjective acidus, sour), an acid; Neo-Latin neuter gender adjective philum (from Greek neuter gender adjective philon (φίλον)), friend, loving; Neo-Latin neuter gender noun Acidiphilium (sic), acid lover.
