These results were consistent with reported changes in the rate of respiration of S. acidocaldarius as a function of temperature and pH. The host cell recovers and remains lysogenic after the viral production; virus is thus released into nature . Es lebt dort in schwefelreichen Quellen, die eine Temperatur bis zu 90 °C erreichen können und einen pH-Wert von 1 bis 5 aufweisen. Sulfolobus strains are found in sulfur-rich hot acid springs occurring in volcanic regions.
