Glomus iranicum var. Tenuihypharum as a Biofertilizer Modulates Soil Microbial Community Composition and Enhances Soil Carbon Dynamics in Nectarine Cultivation

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 3, September 2026.
ABSTRACT The development of biofertilization strategies based on arbuscular mycorrhizal fungi (AMF) represents a promising approach to enhance crop productivity and soil health while reducing the environmental footprint of conventional fertilization. This study evaluated the effects of Glomus iranicum var.

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 ...

Effect of ammonium concentration on methane oxidation and CO2 removal in an anaerobic biotrickling filter treating synthetic landfill gas and leachate

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 8, Page 1632-1642, August 2026.
Abstract BACKGROUND Landfill gas (LFG) and leachate are commonly treated separately through energy‐intensive processes. This study evaluated the integration of both streams in an anaerobic biotrickling filter (BTF) to achieve simultaneous methane (CH4) and carbon dioxide (CO2) removal coupled with ammonium (NH4+) transformation, and how the microbial ...

The response of nitrifier, N-fixer and denitrifier gene copy numbers to the nitrification inhibitor 3,4-dimethylpyrazole phosphate

Plant, Soil and Environment, 2013
A laboratory incubation experiment was conducted to examine the effects of 3,4-dimethylpyrazole phosphate (DMPP) on the transformation of urea-N and associated microbial communities in a low-fertility brown soil. The soil was supplied with urea at 180 kg

Subsurface Production of Marine Derived Bacterial Tetraether Lipids: Implications for Paleoceanographic Reconstruction

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Branched glycerol dialkyl glycerol tetraethers (brGDGTs) are widely used as paleoclimate proxies on land, yet their origin in marine environments remains incompletely constrained. Here, we analyze suspended particulate matter collected from five depths at an open‐ocean station in the northern South China Sea and provide depth‐resolved evidence

Hydroxylamine as an intermediate in ammonia oxidation by globally abundant marine archaea [PDF]

Proceedings of the National Academy of Sciences, 2012
The ammonia-oxidizing archaea have recently been recognized as a significant component of many microbial communities in the biosphere. Although the overall stoichiometry of archaeal chemoautotrophic growth via ammonia (NH 3 ) oxidation to nitrite (NO 2 − ) is superficially similar

Abundance and diversity of nitrogen-removing microorganisms in the UASB-anammox reactor.

PLoS ONE, 2019
Anaerobic ammonium oxidation is considered to be the most economical and low-energy biological nitrogen removal process. So far, anammox bacteria have not yet been purified from cultures.

The effect of pretreatment on VFA production from tofu and tempeh wastewater through anaerobic digestion batch

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 4, Page 1743-1761, July/August 2026.
Abstract Tofu and tempeh, derived from soybeans, are widely consumed for their nutritional value and high protein content. However, the production of these foods generates nutrient‐rich wastewater that poses environmental challenges while offering opportunities for valorization.

Indigenous Ammonia-Oxidizing Archaea in Oxic Subseafloor Oceanic Crust

mSystems, 2020
Oceanic ridge flank systems represent one of the largest and least-explored microbial habitats on Earth. Fundamental ecological questions regarding community activity, recruitment, and succession in this environment remain unanswered.
