Archaea
Archaea are found in a diverse range of extreme environments, including the salt deposits on the shores of the Dead Sea.
In soil ecosystems, uncultivated organisms within the Crenarchaeota subdivision are considered highly significant because they are postulated to be the most abundant ammonia-oxidizing organisms present.1
By facilitating the oxidation of ammonia, these archaea play a vital role in the nitrogen cycle, which is essential for maintaining soil health and supporting plant life. While many cultured representatives of this group are known as extremophiles from high-temperature environments, culture-independent studies have revealed that these diverse, uncultivated members are ubiquitous and fulfill critical ecological roles in various environments, including temperate soils.12
