While there has been a significant recent improvement in the removal of pollutants in natural
and engineered systems, trace organic chemicals (TrOCs) are posing a major threat to …

Ammonia oxidation in the soil is related to nitrogen (N) availability for plants, nitrate loss, and
N fertilizer use efficiency, which is important for studies on the N cycle of paddy field …

Nitrogen fertilization has important effects on nitrification. However, how the rate of nitrogen
fertilization affects nitrification potential, as well as the communities of ammonia-oxidizing …

Ammonia-oxidizing Archaea (AOA) and ammonia-oxidizing Bacteria (AOB) oxidize
ammonia to nitrite, and therefore play essential roles in nitrification and global nitrogen …

Human-driven changes affect nutrient inputs, oxygen solubility, and the hydrodynamics of
lakes, which affect biogeochemical cycles mediated by microbial communities. However …

Terrestrial–marine boundaries are significant sites of biogeochemical activity with
delineated gradients from land to sea. While niche differentiation of ammonia‐oxidizing …

Deep-sea ferromanganese crusts are found ubiquitously on the surface of seamounts of the
world's oceans. Considering the wide distribution of the crusts, archaeal and bacterial …

Up-flow biological activated carbon (BAC) filters have been empirically employed in drinking
water treatment plants (DWTPs) to address the challenges of its down-flow counterparts (eg …

Subsurface microbial communities mediate biogeochemical transformations that drive both
local and ecosystem-level cycling of essential elements, including nitrogen. However, their …

The intertidal zone is an important buffer and a nitrogen sink between land and sea.
Ammonia oxidation is the rate-limiting step of nitrification, conducted by ammonia-oxidizing …
