Sediments From a Seasonally Euxinic Coastal Ecosystem Show High Nitrogen Cycling Potential
The nitrogen cycling potential of sediments from seasonally euxinic Lake Grevelingen was investigated through incubation experiments and 16S rRNA amplicon and shotgun metagenome sequencing. The sediments have a high potential for nitrification, denitrification, and DNRA, but not for anammox. ABSTRACT Coastal ecosystems are susceptible to eutrophication

Recent Advances in Aquaponic Systems: A Critical Review
This article critically examines recent advances in aquaponic systems, identifies knowledge gaps, and proposes future research directions to enhance system performance, economic viability, and environmental sustainability. ABSTRACT Aquaponics, a symbiotic farming of plants and fish, is a promising solution to address global food security.

Nitrogen source influences the interactions of comammox bacteria with aerobic nitrifiers
While the co-existence of comammox Nitrospira with canonical nitrifiers is well documented in diverse ecosystems, there is still a dearth of knowledge about the mechanisms underpinning their interactions.

Read the free Plain Language Summary for this article on the Journal blog. Abstract Interactions between plants and soil microorganisms in the rhizosphere are vital for maintaining the nutrient cycle and stability of terrestrial ecosystems. Nitrogen, closely related to carbon (C) cycling and ecosystem productivity, undergoes transformation by soil ...

Flow-cytometric quantification of microbial cells on sand from water biofilters [PDF]
Rapid quantification of absolute microbial cell abundances is important for a comprehensive interpretation of microbiome surveys and crucial to support theoretical modelling and the design of engineered systems.

ABSTRACT The ammonia monooxygenase subunit A (amoA) gene has been used to investigate the phylogenetic diversity, spatial distribution and activity of ammonia‐oxidising archaeal (AOA) and bacterial (AOB), which contribute significantly to the nitrogen cycle in various ecosystems. Amplicon sequencing of amoA is a widely used method; however, it produces

Growth of comammox Nitrospira is inhibited by nitrification inhibitors in agricultural soils [PDF]
The discovery of comammox Nitrospira being capable of complete oxidising ammonia to nitrate radically challenged the conventional concept of two-step nitrification. However, the response of comammox Nitrospira to nitrification inhibitors (NIs) and their role in soil nitrification remain largely unknown, which has hindered our ability to predict the ...

Differential ecosystem function stability of ammonia-oxidizing archaea and bacteria following short-term environmental perturbation [PDF]
Rapidly expanding conversion of tropical forests to oil palm plantations in Southeast Asia leads to soil acidification following intensive nitrogen fertilization.

Abstract Ammonia‐oxidizing archaea (AOA) and ammonia‐oxidizing bacteria (AOB) control nitrification in terrestrial systems. Soil pH and substrate availability (NH4+) can influence community composition, which may affect the contributions of these organisms to nitrification in forest soils. Using high‐throughput sequencing, we identified the amoA of AOA
