Compared to bacteria, our knowledge of archaeal biology is limited. Historically,
microbiologists have mostly relied on culturing and single-gene diversity surveys to …

Host-associated microbial communities have an important role in shaping the health and
fitness of plants and animals. Most studies have focused on the bacterial, fungal or viral …

Nitrification, as a crucial step in nitrogen cycling and plant nutrition, is a biologically
mediated process responsible for enormous losses of nitrogen fertilizer and a contributor to …

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 …

Atmospheric aerosol particles of biological origin are a very diverse group of biological
materials and structures, including microorganisms, dispersal units, fragments and …

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

The discovery of ammonia oxidation by mesophilic and thermophilic Crenarchaeota and the
widespread distribution of these organisms in marine and terrestrial environments indicated …

Nitrification, the aerobic oxidation of ammonia to nitrate via nitrite, has been suggested to
have been a central part of the global biogeochemical nitrogen cycle since the oxygenation …

Nitrification, the microbial oxidation of ammonia to nitrite and nitrate, occurs in a wide variety
of environments and plays a central role in the global nitrogen cycle. Catalyzed by the …

Ammonia oxidation is the first step in nitrification, a key process in the global nitrogen cycle
that results in the formation of nitrate through microbial activity,. The increase in nitrate …
