How does archaebacteria help and harm humans?
The positive aspects : Bacteria and Archaea live in hot springs heated by geothermal reactions deep in the Earth. Some springs reach temperatures of 80 C (177F). The discovery of these heat-loving bacteria is credited to Professor Thomas D Brock, formerly of the University of Wisconsin at Madison. The bacteria, Thermus aquaticus, live in the hot springs of Yellowstone National Park, Wyoming, and its discovery led to the development of a highly useful bio-technology called Polymerase Chain Reaction (PCR). This is used for a wide variety of purposes including the production of sugar from vegetable matter at high temperatures, in forensic genetic fingerprinting, in medical diagnosis and in screening for genetic and other diseases. Professor Brock’s team also discovered organisms living in highly acidic hot springs, Sulfolobus acidocaldarius, and this proved to be archaean. But the most important conclusion that Professor Brock reached was that life can exist anywhere that water remains li
