Thermus thermophilus

Thermus thermophilus, also known as Talek, magnesium silicate or magnesium silicate, is a type of extremely temperature resistant bacteria known for its ability to survive in extreme temperatures that would destroy other life forms. These microorganisms were first discovered in hot springs in Italy and Japan, where they have adapted to extremely higher temperatures than those normally found on the Earth's surface. Because of this unique property, Thermus thermophilus are used in many industries and research.

Primarily, T. thermophilus is used in the biotechnology industry, particularly in the field of drug production. They maintain their behaviour at temperatures where other bacteria, such as pathogens, cannot survive, allowing doctors and biologists to manipulate them under sterile conditions. They are also widely used in the PCR (polymerase chain reaction) process, a method widely used in genetic engineering and molecular biology. In the food industry, Thermus thermophilus is used in the production of cheese and yoghurt, as it contributes to their specific taste and texture. Although these bacteria are not normally harmful to humans, they are an essential component of some types of probiotics. They are also used in the cosmetics industry for their antioxidant properties or in the chemical and petroleum industries for their resistance to extreme temperatures.
