Most studied thermophilic archaea include Sulfolobus acidocaldarius, Acidianus brierleyi, and Metallosphaera sedula. However, Ferroplasma acidophilum and Ferroplasma acidarmanus are some examples of mesophilic archaea. Classification The domain Archaea includes four kingdoms Crenarchaeota, Euryarchaeota, Korarchaeota, Nanoarchaeota.
Acidianus brierleyi was demonstrated to remove pyritic sulphur from coal.A. brierleyi was also found capable of catalyzing the removal of what is normally reported as organic sulphur from coal 171US34. A kinetic analysis was performed by assuming a first order reaction. The first order kinetics allowed a comparison with literature data for Thiobacillus ferrooxidans.
The kinetics of the biochemical electron transport chain in the optimization of growth and sulfur oxidative potential of Sulfolobus brierleyi are reviewed with reference to organic desulfurization bioconversions (bioprocessing of coal and oil shale).
Abstract. Mineral sulfide concentrate oxidation by thermoacidophilic archaea was reported in the 1970s with a culture which was described as “possibly related to Sulfolobus” but which contained the species later named as Acidianus brierleyi.
Double refractory gold ore was sequentially pretreated to oxidize sulfides by thermophilic archaeon Acidianus brierleyi and then to decompose carbonaceous matters using the cell-free spent medium (CFSM)from white-rot fungus Phanerochaete chrysosporium. The pretreatment by A. brierleyi significantly improved the gold recovery from 25% to 77%.
A comparison of the amino acid sequences of the proteins revealed that the A. tengchongensis SOR shows 100, 88, 66, and 34% sequence identity with the SORs of A. brierleyi and A. ambivalens and the SOR-like proteins of S. tokodaii and A. aeolicus, respectively. Interestingly, all of these proteins carry three cysteine residues.
FULL TEXT Abstract: A novel thermoacidophilic iron and sulfur-oxidizing archaeon, strain YN25, was isolated from an in situ enriched acid hot spring sample collected.

The effect of microbial desulfurization of two different low-sulfur coals by the thermophilic archaebacteria Acidianus brierleyi was studied with respect to the following properties of the coal: porosity, surface area, pore diameter, particle size, heating value, proximate and ultimate analyses as well as ash composition.

Jim’s research on the contributions of bacteria to the chemistry of acid hot springs led to the discovery of the first high temperature (thermophilic), acid-loving microorganism that later became known as Acidianus brierleyi - named by German scientists in honour of Jim.

Acidianus (n.). 1. A genus of facultatively anaerobic coccoid ARCHAEA, in the family SULFOLOBACEAECells are highly irregular in shape and thermoacidophilic. Lithotrophic growth occurs aerobically via sulfur oxidation in some species.
