Question

A population of thermophilic archaebacteria are generally found in hot springs. Any change to the
temperature of the water affects the survival of the archaebacteria. If the temperature of hot springs gets
reduced, change in which component can allow survival of few members of these archaebacteria?

Answer 1

Answer:

Archaebacteria are a group of microorganisms considered to be an ancient form of life that evolved separately from the bacteria and blue-green algae, and they are sometimes classified as a kingdom. Hyperthermophilic (ie, high-temperature-loving) archaebacteria, found in submarine hydrothermal areas (see Stetter, 1982; Segerer, et al., 1985; Stetter, 1986; Huber et al., 1989; Neuner et al., 1990), thrive at temperatures in the range 80-110°C, and they are unable to grow below 60°C. Various extremely thermophilic archaebacteria exhibit optimum growth at above 80°C. Pyrodictium is the most thermophilic of these organisms, growing at temperatures of up to 110°C and exhibiting optimum growth at about 105°C.
