Acidiphilium Explained

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 FeIII (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.

Species

The genus contains 6 species (including basonyms and synonyms), namely

• A. acidophilum ((Harrison 1983) Hiraishi et al. 1998; 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 adjective acidophilum, acid loving.), this species used to known as Thiobacillus acidophilus^[1]
• A. angustum (Wichlacz et al. 1986; Latin neuter gender adj, angustum, narrow, small, with respect to nutritional versatility.)^[2]
• A. cryptum (Harrison 1981, (Type species of the genus).; Neo-Latin neuter gender adjective cryptum (from Greek noun adjective ), hidden.)^[3]
• Latin: [[Acidiphilium multivorum|A. multivorum]] (Wakao et al. 1995; Latin adjective multus, many; Latin v. voro, to eat, devour; Neo-Latin neuter gender adjective Latin: multivorum, devouring many kinds of substances.)^[4]
• Latin: [[Acidiphilium organovorum|A. organovorum]] (Lobos et al. 1986; Neo-Latin pref. organo- (from Greek adjective , of or pertaining to an organ), pertaining to organic chemical compounds; Latin v. voro, to eat, devour; Neo-Latin neuter gender adjective Latin: organovorum, devouring organic compounds.)^[5]
• A. rubrum (Wichlacz et al. 1986; Latin adjective ruber -bra -brum, red; Latin neuter gender adjective rubrum, red colored.)^[2] Acidocella aminolytica and Acidocella facilis used to be in this genus.^[6]
