This so-called hyperthermophilic microbe, discovered in a 95â (203â) geothermal pool, is only the second member of the ancient group Archaea known to grow by digesting cellulose above 80â. And the microbeâs cellulase is the most heat tolerant enzyme found in any cellulose-digesting microbe, including bacteria.
When the microbes cause diseases, however, uncontrolled growth can lead to people becoming more sick or dying. In laboratories that work with microbes, controlling their growth is essential for obtaining useful experimental results.n order to be effective, though, the ethanol must be left on the surface long enough to kill the microbes. Radiation is also effective at killing microbes. One common type of radiation used is ultraviolet, the same type that is found in sunlight.
