Question
Chapter 20.1, Problem 2MI
Summary Introduction
Halophilic archaea are also termed as haloarchaea, which thrive in a hypersaline environment. To survive in extreme environments like high salt concentrations and extreme temperature and pH, haloarchaea and their enzymes have evolved to act optimally.

Examine the graph shown below of a liquid culture growth curve for S. pneumoniaegrowing in minimal broth containing both glucose and lactose in equal concentrations as a potential carbon source. Answer the following questions:
a) Name the growth phases labelled as I, II and III, explain the observed pattern of growth at each of these stages in the curve
b) Where would the concentration of cAMP be low and why?
c) In what phase would β-galactosidase be high and why?
d) What kind of overall growth pattern does this curve illustrate?
How might the temperature and pH tolerance of ahyperthermophile living in a solfatara differ from that of ahyperthermophile living in a hydrothermal vent?
Some halophiles often have an extremely high amino acid concentration in the cell and grow at pH of 7.1 with the intracellular pH being similar. Why might the high amino acid concentration allow these cells to live in high-salt environments?
