Abstract

A.ci.di.lo'bus L. masc. adj. acidus, acid; Gr. masc. n. lobos, lobe; N.L. masc. n. Acidilobus, the “acid lobe”.

Crenarchaeota / Thermoprotei / Acidilobales / Acidilobaceae / Acidilobus

Genus Acidilobus belongs to the family Acidilobaceae, order Acidilobales. Organisms of this genus have coccoid cells, with or without flagellation. They inhabit terrestrial acidic hot springs and have temperature and pH optima for growth at 81–92°C and 3.0–3.8, respectively, thus being hyperthermophiles and acidophiles. All known representatives of Acidilobus are obligate anaerobes growing on peptides, polysaccharides, and sugars, with or without elemental sulfur as the electron acceptor. Acetate is the major metabolic product, while molecular hydrogen has never been detected, which is in agreement with the absence of hydrogenase genes in the genome of Acidilobus saccharovorans. Analysis of the microbial diversity in acidic hot springs of Kamchatka and Yellowstone National Park showed that Acidilobaceae is a widespread group of prokaryotes abundant in these habitats.

DNA G + C content (mol%): 53.8–54.5.

Type species: Acidilobus aceticus Prokofeva, Miroshnichenko, Kostrikina, Chernyh, Kuznetsov, Tourova and Bonch-Osmolovskaya 2000, 2007^VP
