Abstract: Urea nitrogen has been proposed to contribute significantly to nitrification by marine thaumarchaeotes. These inferences are based on distributions of thaumarchaeote urease genes rather than activity measurements. We found that ammonia oxidation rates were always… read more here.

Abstract: Thaumarchaeota are among the most abundant prokaryotes in the ocean, playing important roles in carbon and nitrogen cycling. Marine Thaumarchaeota ecotypes exhibit depth-related diversification and seasonal changes. However, transcriptomic activities concerning niche partitioning among thaumarchaeal… read more here.

Abstract: Ammonia-oxidizing Archaea, or Thaumarchaeota (Spang et al., 2010), are an abundant and widespread group of prokaryotes. They are particularly abundant in the mesopelagic zone of the open ocean (Karner et al., 2001) and in oxygen… read more here.

Abstract: Group I mesophilic Thaumarchaeota fix dissolved inorganic carbon (DIC), accompanied by a biosynthetic fractionation factor of ~20‰. Accordingly, the δ13C signature of their diagnostic biomarker crenarchaeol was suggested as a potential δ13CDIC proxy in marine… read more here.

DOI: 10.3389/fmicb.2017.01200
Abstract: Crenarchaeol is a unique isoprenoid glycerol dibiphytanyl glycerol tetraether (iGDGT) lipid, which is only identified in cultures of ammonia-oxidizing Thaumarchaeota. However, the taxonomic origins of crenarchaeol have been debated recently. The archaeal populations, other than… read more here.
