Cloning, mutagenesis, and nucleotide sequence of a siderophore biosynthetic gene (amoA) from Aeromonas hydrophila [PDF]
Journal of Bacteriology, 1991 Many isolates of the Aeromonas species produce amonabactin, a phenolate siderophore containing 2,3-dihydroxybenzoic acid (2,3-DHB). An amonabactin biosynthetic gene (amoA) was identified (in a Sau3A1 gene library of Aeromonas hydrophila 495A2 chromosomal DNA) by its complementation of the requirement of Escherichia coli SAB11 for exogenous 2,3-DHB to ...

Environmental Microbiome, 2019 Background Characterisation of microbial communities increasingly involves use of high throughput sequencing methods (e.g. MiSeq Illumina) that amplify relatively short sequences of 16S rRNA or functional genes, the latter including ammonia monooxygenase

High-throughput analysis of ammonia oxidiser community composition via a novel, amoA-based functional gene array. [PDF]
PLoS ONE, 2012 Advances in microbial ecology research are more often than not limited by the capabilities of available methodologies. Aerobic autotrophic nitrification is one of the most important and well studied microbiological processes in terrestrial and aquatic ...

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.ABSTRACT Abalone are economically, ecologically and culturally significant marine molluscs, with both wild and farmed populations under pressure due to intrinsic and extrinsic stressors. Abalone performance and health are centred on a highly specialized digestive system supported by a diverse gut microbiome, which enables nutrient assimilation ...

Ammonia-Oxidizer Communities in an Agricultural Soil treated with Contrasting Nitrogen Sources.
Frontiers in Microbiology, 2013 The community of ammonia-oxidizing prokaryotes was examined in an agricultural soil treated for 6 seasons with contrasting nitrogen (N) sources. Molecular tools based on the gene encoding ammonia monooxygenase were used to characterize the ammonia ...

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.This review synthesizes current evidence on the nutritional composition of African catfish (Clarias gariepinus), with emphasis on Ghanaian aquaculture. The species is a valuable source of high‐quality protein, essential amino acids, minerals and vitamins, although lipid composition varies widely.

Environmental Microbiology, Volume 28, Issue 8, August 2026.Microbial communities in a Mediterranean subterranean estuary show spatially structured nitrogen‐cycling potential across hydrochemical zones. Microbial properties, more than environmental variables, predict NO2− and NH4+ concentrations, highlighting their key role in controlling nitrogen transformations prior to submarine groundwater discharge ...

Long-term impacts of disturbance on nitrogen-cycling bacteria in a New England salt marsh
Frontiers in Microbiology, 2015 Recent studies on the impacts of disturbance on microbial communities indicate communities show differential responses to disturbance, yet our understanding of how different microbial communities may respond to and recover from disturbance is still ...
