Distribution and Activity of Ammonia-Oxidizers on the Size-Fractionated Particles in the Pearl River Estuary

Frontiers in Marine Science, 2021
To distinguish between the distribution and activity of ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA) in the Pearl River estuary (PRE), we investigated the DNA- and cDNA-based β-proteobacterial and archaeal amoA genes on three size-

Influence of oxygen availability on the activities of ammonia‐oxidizing archaea

Environmental Microbiology Reports, 2017
Summary Recent studies point to the importance of oxygen (O 2 ) in controlling the distribution and activity of marine ammonia‐oxidizing archaea (AOA), one of the most abundant prokaryotes in the ocean. The AOA are associated with regions of low O 2

Abundance of Ammonia-Oxidizing Archaea and Bacteria along an Estuarine Salinity Gradient in Relationship to Potential Nitrification Rates [PDF]

, 2010
Abundance of ammonia-oxidizing Archaea (AOA) was found to be always greater than that of ammonia-oxidizing Bacteria along an estuarine salinity gradient, and AOA abundance was highest at intermediate salinity.

Ammonia oxidizers offset acidification stress via adaptive substrate affinity in aquatic ecosystems

Nature Communications
Ammonia oxidation, a critical nitrogen cycle process, exhibits contradictory responses to aquatic acidification, and the underlying mechanism remains unresolved. Here, through pH manipulation experiments across diverse ecosystems and with a model ammonia-

Enhancing Meat Quality Through Dietary Fiber: Insights Into the Gut Microbiota‐Derived Short‐Chain Fatty Acids‐Muscle Axis

Animal Research and One Health, EarlyView.
Dietary fiber (DF) modulates meat quality through the gut‐muscle axis by reshaping gut microbiota, improving intestinal integrity, reducing inflammation, and regulating muscle metabolism. These mechanisms influence muscle fiber characteristics and post‐mortem biochemistry, thereby enhancing tenderness, juiciness, color, flavor, and nutritional value of

Influences of soil properties on archaeal diversity and distribution in the McMurdo Dry Valleys, Antarctica [PDF]

, 2011
The Antarctic Dry Valleys are characterized by extremely low temperatures, arid conditions, high salinity and virtual absence of plants. Therefore, food webs of these microbially dominated soils are among the simplest on earth making these mineral soils ...

Abundance and composition of ammonia‐oxidizing bacteria and ammonia‐oxidizing archaea communities of an alkaline sandy loam [PDF]

Environmental Microbiology, 2008
Summary The abundance and composition of soil ammonia‐oxidizing bacteria (AOB) and ammonia‐oxidizing archaea (AOA) communities under different long‐term (17 years) fertilization practices were investigated using real‐time polymerase chain reaction and denaturing gradient gel electrophoresis (DGGE).

Ammonium Availability Affects the Ratio of Ammonia-Oxidizing Bacteria to Ammonia-Oxidizing Archaea in Simulated Creek Ecosystems

, 2011
The ammonia-oxidizing microbial community colonizing clay tiles in flow channels changed in favor of ammonia-oxidizing bacteria during a 12-week incubation period even at originally high ratios of ammonia-oxidizing archaea to ammonia-oxidizing bacteria ...
