Abstract

New Zealand has extensive thermal regions which, unlike those of other parts of the world, are easily accessible at all seasons of the year. The hot springs of these regions are diverse in mineral composition, acidity and temperature. Only bacteria can live at temperatures higher than 65°C, and those growing optimally at 65°C or higher are called extreme thermophiles. Currently biochemical and physiological studies of extremely thermophilic bacteria are being made by the Thermophile Research Unit at the University of Waikato alongside studies of the ecology of the hot springs from which the bacteria are isolated.
