The understanding of nitrogen (N) cycling in forest ecosystems has undergone a major shift
in the past decade as molecular methods are being used to link microorganisms to key …

Glycerol dialkyl glycerol tetraether (GDGT) lipids are membrane lipids which were long
thought to be synthesized mainly by archaea, organisms thought to be limited to extreme …

Ammonia-oxidising archaea (AOA) are ubiquitous and abundant in nature and play a major
role in nitrogen cycling. AOA have been studied intensively based on the amoA gene …

Archaea, primarily Crenarchaeota, are common in soil; however, the structure of soil
archaeal communities and the factors regulating their diversity and abundance remain …

Archaea of the phylum Thaumarchaeota are among the most abundant prokaryotes on Earth
and are widely distributed in marine, terrestrial, and geothermal environments. All studied …

Marine sponges (phylum Porifera) often contain dense and diverse microbial communities,
which can constitute up to 35% of the sponge biomass. The genome of one sponge …

Genes of archaea encoding homologues of ammonia monooxygenases have been found
on a widespread basis and in large amounts in almost all terrestrial and marine …

Increasing evidence demonstrated the involvement of ammonia-oxidizing archaea (AOA) in
the global nitrogen cycle, but the relative contributions of AOA and ammonia-oxidizing …

Virtually all nonequilibrium electron transfers on Earth are driven by a set of nanobiological
machines composed largely of multimeric protein complexes associated with a small …

Autotrophic CO2 fixation represents the most important biosynthetic process in biology.
Besides the well-known Calvin-Benson cycle, five other totally different autotrophic …
