Ammonia-oxidizing archaea and complete ammonia-oxidizing Nitrospira in water treatment systems
Nitrification, the oxidation of ammonia to nitrate via nitrite, is important for many engineered water treatment systems. The sequential steps of this respiratory process are carried out by distinct microbial guilds, including ammonia-oxidizing bacteria (

Principles for Rigorous Design and Application of Synthetic Microbial Communities
SynComs are artificially designed to enable inter‐species metabolic interactions, metabolic division of labor, and ecological interactions that can elicit phenotypes like colonization stability and environmental adaptation. This systematic review explores the processes used to construct SynComs, the assessment of the mechanisms of metabolic interaction

Spatial and Temporal Variability of Microbial Nitrogen Cycling Genes in Arctic Streams
Abstract The Arctic is undergoing rapid climate change, with thawing permafrost and shifts in vegetation altering nitrogen (N) delivery into streams. These changes can significantly affect microbial biofilm diversity and functional roles, yet knowledge of streambed microbial biofilms remains scarce across the Arctic.

Impact of comammox process on membrane-aerated biofilm reactor for autotrophic nitrogen removal
This study compared the simulation results of the side-stream membrane-aerated biofilm reactor (MABR) in terms of total nitrogen (TN) removal and N2O production obtained by the conventional comammox-exclusive biological nitrogen removal (BNR) model and ...

Growth of complete ammonia oxidizers on guanidine. [PDF]
Guanidine is a chemically stable nitrogen compound that is excreted in human urine and is widely used in manufacturing of plastics, as a flame retardant and as a component of propellants, and is well known as a protein denaturant in biochemistry 1–3 ...

The impact of plant identity and interspecific interactions on the soil microbiome in intensively managaged grasslands. ABSTRACT Plants and soil microbes are intricately linked, and agricultural production relies heavily on microbially mediated ecosystem services. However, the effects of plant diversity (richness, relative abundance and composition) on

Community Composition and Abundance of Bacterial, Archaeal and Nitrifying Populations in Savanna Soils on Contrasting Bedrock Material in Kruger National Park, South Africa [PDF]
Savannas cover at least 13% of the global terrestrial surface and are often nutrient limited, especially by nitrogen. To gain a better understanding of their microbial diversity and the microbial nitrogen cycling in savanna soils, soil samples were ...

Nitrite-oxidizing bacteria (NOB) catalyze the second step of nitrification, which is an important process of the biogeochemical nitrogen cycle and is exploited extensively as a biological nitrogen removal process.

This study reveals how soil pH regulates microbial N allocation in forest soils across Japan. We show that microbial abundance controls the overall rate of N cycling, while microbial composition and metabolic potential determine whether ammonium is released or retained.
