Thaumarchaeota are among the most widespread organisms and occur in virtually all sampled environments. So far all cultivated representatives perform aerobic ammonia oxidation (AOA), which is the first and rate limiting step in the process of nitrification. Themophilic Thaumarchaeota are of particular interest, because phylogenies based on 16S rRNA, ribosomal proteins and amoA genes, all suggest a thermophilic origin of the now very versatile Thaumarchaeota. We present a highly enriched culture of a thermophilic Thaumarchaeon obtained from a hot spring in Ischia (Italy). Genomic analysis and physiological data will be presented to shed light on the metabolic capabilities and genomic features illustrating the possible mechanisms that led to the radiation of AOA from hot to temperate environments.
