Nitrogen removal in a two-chambered microbial fuel cell: Establishment of a nitrifying-denitrifying microbial community on an intermittent aerated cathode [PDF]

, 2016
A microbial fuel cell (MFC) was used to study nitrogen dynamics and its feasibility for high strength wastewater treatment. Intermittent aeration was applied on the cathode chamber accomplishing the establishment of a simultaneous nitrifying-denitrifying

Methanol and Carbon Monoxide Metabolism of the Thermophile Moorella caeni

Environmental Microbiology, Volume 27, Issue 4, April 2025.
An omics approach was used to elucidate the C1 metabolism of Moorella caeni DSM 21394 T, which exhibits acetogenic metabolism on methanol and hydrogenogenic metabolism on CO. Our results suggest that respiratory Complex I serves as the primary respiratory enzyme in methanol‐grown cells.

Probe Capture Enrichment Sequencing of amoA Genes Improves the Detection of Diverse Ammonia‐Oxidising Archaeal and Bacterial Populations

Molecular Ecology Resources, Volume 25, Issue 3, April 2025.
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

Comparative in silico analysis of PCR primers suited for diagnostics and cloning of ammonia monooxygenase genes from ammonia-oxidizing bacteria [PDF]

, 2017
Over recent years, several PCR primers have been described to amplify genes encoding the structural subunits of ammonia monooxygenase (AMO) from ammonia-oxidizing bacteria (AOB).

Application of COMPOCHIP Microarray to Investigate the Bacterial Communities of Different Composts [PDF]

, 2009
A microarray spotted with 369 different 16S rRNA gene probes specific to microorganisms involved in the degradation process of organic waste during composting was developed. The microarray was tested with pure cultures, and of the 30,258 individual probe-

Nitrogen Availability and Changes in Precipitation Alter Microbially Mediated NO and N2O Emissions From a Pinyon–Juniper Dryland

Global Change Biology, Volume 31, Issue 3, March 2025.
ABSTRACT Climate change is altering precipitation regimes that control nitrogen (N) cycling in terrestrial ecosystems. In ecosystems exposed to frequent drought, N can accumulate in soils as they dry, stimulating the emission of both nitric oxide (NO; an air pollutant at high concentrations) and nitrous oxide (N2O; a powerful greenhouse gas) when the ...

Physiological function and catalytic versatility of bacterial multihaem cytochromescinvolved in nitrogen and sulfur cycling [PDF]

, 2011
Bacterial MCCs (multihaem cytochromes c) represent widespread respiratory electron-transfer proteins. In addition, some of them convert substrates such as nitrite, hydroxylamine, nitric oxide, hydrazine, sulfite, thiosulfate or hydrogen peroxide. In many

Effect of Dietary Protein Levels on Growth, Body Composition, and Haematology of Tilapia in Biofloc Without Solid Management System

Aquaculture, Fish and Fisheries, Volume 5, Issue 1, February 2025.
ABSTRACT This study investigated the effects of varying dietary protein levels on the performance of tilapia reared in biofloc culture system without solid management. Five experimental diets containing crude protein (CP) levels of 32, 28, 24, 20, and 16% were tested in a completely randomized design in triplicate.
