Abstract

Archaen are one of the three domains of life (the other two domains are Bacteria and Eukarya). These organisms all lack peptidoglycan in their cell walls, contain ether-linked lipids, and have complex RNA polymerases [Madigan etal., 2008]. Based on 16S rRNA gene analysis [Woese and Fox, 1977; Woese etal., 1990; see also Chapter 15, Vol. 1], Archaea were initially classified into two phyla, Crenarchaeota and Euryarchaeota. With advancements in both microbial cultivation approaches and molecular microbiology, three new phyla have been proposed in recent years, the Korarchaeota [Barns etal.,1996], the Nanoarchaeota (Huber etal., 2002), and the Thaumarchaeota [Brochier-Armanet et al., 2008].To date, Korarchaeota have only been reported from geothermal environments, whereas Crenarchaeota and Euryarchaoeta exist in nearly every niche on the planet Earth. Thaumarchaeota is currently defined to be a group of archaea that exist in low-temperature environments [Brochier-Armanet etal., 2008].
