The thermostable DNA polymerase, often referred to as Taq polymerase, was indeed isolated from this bacterium. Taq polymerase is able to withstand the high temperatures used in the polymerase chain reaction (PCR), making it ideal for this application. Other bacteria listed (Escherichia coli, Agrobacterium tumefaciens, Bacillus thuringiensis) are not known for having thermostable DNA polymerases used in PCR.
