In today's world, there is an increasing trend towards the use of renewable, cheap and
readily available biomass in the production of a wide variety of fine and bulk chemicals in …

In the late 1970s, on the basis of rRNA phylogeny, Archaea (archaebacteria) was identified
as a distinct domain of life besides Bacteria (eubacteria) and Eucarya. Though forming a …

Many archaea colonize extreme environments. They include hyperthermophiles, sulfur‐
metabolizing thermophiles, extreme halophiles and methanogens. Because extremophilic …

Sulfolobus solfataricus has developed into an important model organism for molecular and
biochemical studies of hyperthermophilic archaea. Although a number of in vitro systems …

The most thermoactive α-amylases that have been purified and characterized are those from
the archaeon Pyrococcus woesei (Koch et al. 1991) and P. furiosus (Brown et al. 1990; Koch …

Only in the last decade have microorganisms been discovered which grow near or above
100° C. The enzymes that are formed by these extremely thermophilic (growth temperature …

In recent years a number of hyperthermophiles with the ability to utilize sugars as source for
carbon and energy have been isolated. Analysis of their central metabolism may reveal …

During the last decades, the impact of hyperthermophiles and their enzymes has been
intensively investigated for implementation in various high-temperature biotechnological …

Extremely thermophilic microorganisms have been sources of thermostable and
thermoactive enzymes for over 30 years. However, information and insights gained from …

Galacto-oligosaccharides (GOS), an important class of functional food, are commonly
produced from lactose using β-galactosidase. In the present study, β-galactosidase (LacS) …
