An aerobic, Gram-negative, heterotrophic, thermophilic bacterium discovered in the natural hot springs of Yellowstone National Park, Wyoming. This bacterium became the source of the Taq DNA polymerase used in the polymerase chain reaction (q.v.) and the Taq DNA ligase used in the ligase chain reaction (q.v.). T. aquaticus is also the source of the ribosomes that were used in the crystallographic studies which showed the 3D structure of 70S ribosomes complexed with tRNA and mRNA molecules.
