The abundance of nitrogen compounds, phosphorous compounds and organic matter in
biofloc technology (BFT) aquaculture systems creates an ideal medium for increasing …

Nitrification, the oxidation of ammonia to nitrite and nitrate, has long been considered a
central biological process in the global nitrogen cycle, with its first description dated 133 …

The atmospheric concentration of methane (CH4), a major greenhouse gas, is mainly
controlled by the activities of methane-producing (methanogens) and methane-consuming …

Inhibition by light potentially influences the distribution of ammonia oxidizers in aquatic
environments and is one explanation for nitrite maxima near the base of the euphotic zone …

Thaumarchaeota (now the class Nitrososphaeria in the phylum Thermoproteota in GTDB
taxonomy) are abundant across marine and soil habitats; however, their genomic diversity …

Ammonia oxidation plays a significant role in the nitrogen cycle in marine sediments.
Ammonia-oxidizing archaea (AOA) and bacteria (AOB) are the key contributors to ammonia …

Northern lakes are ice‐covered for a large part of the year, yet our understanding of
microbial diversity and activity during winter lags behind that of the ice‐free period. In this …

Background The global distribution of ammonia-oxidizing archaea (AOA), which play a
pivotal role in the nitrification process, has been confirmed through numerous ecological …

High mountain lakes are extreme freshwater ecosystems and excellent sentinels of current
global change. They are likely among the most comparable ecosystems across the world …

Ammonia oxidation is the first step of nitrification carried out by ammonia-oxidizing Archaea
(AOA) and Bacteria (AOB). Lake Superior and Erie are part of the Great Lakes system …
