Thermus thermophilus
Thermus thermophilus is a gram-negative eubacterium, and is used in many biotechnological processes. Optimal growth is 49 ° to 72 ° C, the bacterium is thus highly thermophilic. Thermus thermophilus was found in hot springs in Japan and is divided into several subtypes. The most common one is concerned with the subtypes HB8 and HB27, whose genome was deciphered in 2004.
Thermus thermophilus is relevant for the polymerase chain reaction thermostable polymerase ( Tth ) is obtained. It catalyses with optimum activity at 70 to 80 ° C. The enzyme requires divalent ions.
