Sulfolobus acidocaldarius is an Archaean extremophile. This strictly aerobic prokaryote is found in the searing temperatures of sulfur-rich geothermal hot acid springs, geysers, and deep ocean vents. While primarily an aquatic organism, S. acidocaldarius can also be found in hot acidic soils. Optimal conditions for S. acidocaldarius included a temperature of 80°C and a hydronium ion concentration, pH, of 2; making them acidophiles (acid loving) and thermophiles (heat loving). (Wikipedia #2). As a member of the Archaea Domain, S. acidocaldarius, has no peptidoglycan within its membrane. As such it cannot be classified as gram positive or gram negative. Nutritionally speaking S. acidocaldarius can grow chemoautotrophically using sulfur to oxidize simple reduced carbon compounds or lithoautotrophically by oxidizing sulfur (Wikipedia #2). S. acidocaldarius’ metabolic byproduct is sulfuric acid, thus this organism is responsible for the sulfuric acid concentrations in the environments which they inhabit.
Collectively the species within the genus Sufolobus are named after the location from which the genus was originally isolated. S. solfataricus was first species isolated in the Solfatara volcano. Solfatara is a shallow volcanic crater at Pozzuoli, near Naples, part of the Campi Flegrei volcanic area. It is a dormant volcano, which still emits jets of steam with sulfurous fumes (Wikipedia #12). I was unable to find the origin of the latter portion of my organism’s name. However, I…
