Immobilization of active ammonia-oxidizing archaea in hydrogel beads

npj Clean Water, 2021
Ammonia-oxidizing archaea (AOA) are major players in the nitrogen cycle but their cultivation represents a major challenge due to their slow growth rate and limited tendency to form biofilms. In this study, AOA was embedded in small (~2.5 mm) and large (~

Mixed Litter Decomposition Drives Functional Gene Rearrangement in the Microbial Carbon Cycle

Land Degradation &Development, EarlyView.
ABSTRACT Understanding how mixed‐species litter decomposition regulates microbial communities and carbon cycling is vital for guiding ecosystem restoration and climate change mitigation, as it is a key process for nutrient cycling and carbon sequestration. A 15‐month field experiment compared single‐species (Pinus sylvestris var.

Exploring protein N-glycosylation in ammonia-oxidizing Nitrososphaerota archaea through glycoproteomic analysis

mBio
Ammonia-oxidizing archaea of the phylum Nitrososphaerota, formerly known as Thaumarchaeota, are globally distributed and play critical roles in the nitrogen and carbon cycles, particularly in environments with low ammonia concentrations.

Benzimidazole Anthelmintic Compounds Albendazole and Fenbendazole Show Distinct Toxicity on the Nitrogen Fixing Bacterium Mesorhizobium loti and Its Symbiosis With Lotus japonicus

Environmental Toxicology, EarlyView.
ABSTRACT Veterinary medicines, which reach the soil mostly through the application of contaminated manures, can affect beneficial soil microorganisms, such as nitrogen‐fixing rhizobia bacteria, which engage in important symbiotic associations with plants.

Searching for Ammonia-Oxidizing Archaea [PDF]

, 2017
The Colorado River Basin runs through multiple states in the West of the United States and is a prime water source for about 30 million people in our nation and is used for much of the farmland and agricultural needs in this area.

Cotton Farming Pesticides Affect Ileal Microbiota Activity and Expression of Virulome but Not Resistome or Metabolic Pathways in a Sedentary Wild Passerine

Environmental Toxicology, EarlyView.
ABSTRACT The increased use of agrochemicals to enhance crop production has had detrimental environmental effects including implication in the sharp decline of North American farmland‐breeding birds. Here, using a combination of deep shotgun metatranscriptomics and pesticide exposure data, we sought to assess whether exposure to cotton (Gossypium spp ...

Isolation, cultivation, and characterization of ammonia-oxidizing bacteria and archaea adapted to low ammonium concentrations [PDF]

, 2011
Ammonia-oxidizing microorganisms (AOM) generate their energy by the oxidation of ammonia (NH3) to nitrite (NO2−). This process can be carried out by ammonia-oxidizing bacteria (AOB) as well as by the recently discovered ammonia-oxidizing archaea (AOA ...
