Sulfolobus

[səl′fäl·ə·bəs]
(microbiology)
A genus of bacteria that is gram-negative, coccoid, chemolithotrophic, and thermoacidophilic. It is found worldwide in sulfur-rich hot springs and oxidizes sulfur for energy production. Its cells are highly irregular in shape, often lobed, but occasionally spherical.
