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.

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.

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 ...

Research progress on the physiological metabolic mechanisms and distribution in water treatment systems of ammonia-oxidizing microorganisms

Gongye shui chuli
Nitrification and denitrification processes play crucial roles in biological nitrogen removal in water treatment systems. The ammonia oxidation in nitrification is the rate-limiting process, which converts low-valent ammonia-nitrogen into high-valent ...

Analysis of Carbohydrates and Glycoconjugates by Matrix‐Assisted Laser Desorption/Ionization Mass Spectrometry: An Update for 2023–2024

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The use of MALDI mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this comprehensive review is the twelfth update of the original article published in 1999 and brings coverage of the literature to the end of 2024.

Ammonia-oxidizing archaea and bacteria are structured by geography [PDF]

, 2013
Introduction Biological soil crusts (BSCs) can dominate surface cover in dry lands worldwide, playing an integral role in arid land biogeochemistry, particularly in N fertilization through fixation and cycling.

Ammonia‐oxidizing archaea: important players in paddy rhizosphere soil? [PDF]

Environmental Microbiology, 2008
Summary The diversity (richness and community composition) of ammonia‐oxidizing archaea (AOA) and bacteria (AOB) in paddy soil with different nitrogen (N) fertilizer amendments for 5 weeks were investigated using quantitative real‐time polymerase chain reaction, denaturing gradient gel electrophoresis (DGGE) jand ...

Ecophysiological Characterization of Ammonia-Oxidizing Archaea and Bacteria from Freshwater [PDF]

Applied and Environmental Microbiology, 2012
ABSTRACT Aerobic biological ammonia oxidation is carried out by two groups of microorganisms, ammonia-oxidizing bacteria (AOB) and the recently discovered ammonia-oxidizing archaea (AOA). Here we present a study using cultivation-based methods to investigate the differences in growth of three AOA cultures and one AOB culture ...

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.
