Journal ArticleDOI
A moderately thermophilic ammonia-oxidizing crenarchaeote from a hot spring.
Roland Hatzenpichler,Elena V. Lebedeva,Eva Spieck,Kilian Stoecker,Andreas Richter,Holger Daims,Michael Wagner +6 more
TL;DR: The enriched AOA, which is provisionally classified as “Candidatus Nitrososphaera gargensis,” is the first described thermophilic ammonia oxidizer and the first member of the crenarchaeotal group I.1b for which ammonium oxidation has been verified on a cellular level.
A moderately thermophilic ammonia-oxidizing crenarchaeote from a hot spring.

Journal ArticleDOI
Distinct gene set in two different lineages of ammonia-oxidizing archaea supports the phylum Thaumarchaeota.
Anja Spang,Roland Hatzenpichler,Céline Brochier-Armanet,Thomas Rattei,Thomas Rattei,Patrick Tischler,Eva Spieck,Wolfgang R. Streit,David A. Stahl,Michael Wagner,Christa Schleper +10 more
TL;DR: Phylogenetic studies based on r-proteins and other core genes, as well as comparative genomics, confirm the assignment of archaea comprising ammonia oxidizers of moderate terrestrial and marine environments to a separate phylum and reveal a Thaumarchaeota-specific set of core informational processing genes.
Journal ArticleDOI
Diversity, physiology, and niche differentiation of ammonia-oxidizing archaea.
TL;DR: This minireview provides a synopsis of the current knowledge of the diversity and physiology of AOA, the factors controlling their ecology, and their role in carbon cycling as well as their potential involvement in the production of the greenhouse gas nitrous oxide.
Journal ArticleDOI
The genome of the ammonia-oxidizing Candidatus Nitrososphaera gargensis: insights into metabolic versatility and environmental adaptations.
Anja Spang,Anja Poehlein,Pierre Offre,Sabine Zumbrägel,Susanne Haider,Nicolas Rychlik,Boris Nowka,Christel Schmeisser,Elena V. Lebedeva,Thomas Rattei,Christoph Böhm,Markus Schmid,Alexander Galushko,Roland Hatzenpichler,Thomas Weinmaier,Rolf Daniel,Christa Schleper,Eva Spieck,Wolfgang R. Streit,Michael Wagner +19 more
TL;DR: The complete genome sequence of Candidatus Nitrososphaera gargensis is obtained from an enrichment culture, representing a different evolutionary lineage of AOA frequently found in high numbers in many terrestrial environments and it is shown that thaumarchaeota produce cofactor F420 as well as polyhydroxyalkanoates.
