Novel insights into the Thaumarchaeota in the deepest oceans: their metabolism and potential adaptation mechanisms [PDF]
, 2020 Background: Marine Group I (MGI) Thaumarchaeota, which play key roles in the global biogeochemical cycling of nitrogen and carbon (ammonia oxidizers), thrive in the aphotic deep sea with massive populations.

Primer evaluation and development of a droplet digital PCR protocol targeting amoA genes for the quantification of Comammox in lakes [PDF]
Scientific Reports, 2021 AbstractTo date, little is known about the ecological significance of Comammox (COMplete AMMonia OXidizers) Nitrospira in the water column of freshwater lakes. Water samples collected along depth profiles were used to investigate the distribution of Comammox in 13 lakes characterized by a wide range of physicochemical properties.

Journal of Industrial Microbiology & Biotechnology, 2010 A population shift of ammonia-oxidizing bacteria (AOB) was described within a bench-scale activated sludge process treating an industrial wastewater in a previous report (Kuo et al. in Environ Eng Sci 23:507-520, 2006). In this investigation, transcriptional levels (amoA mRNA-based) of the three AOB groups (i.e., RI-27, B2-3, and Nitrosomonas nitrosa ...

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 ...

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
