Serological studies on lithotrophic, ammonia oxidizing bacteria

open access: yesArchives of Microbiology, 1980
Rabbit antisera were prepared against living cells of six different ammonia oxidizing nitrifying bacteria. They were examined as to cross-reactivity in the agglutination test (Microtiter-system) with 24 nitrifier strains, including members of all known genera.

Reactivation of Microbial Strains and Synthetic Communities After a Spaceflight to the International Space Station: Corroborating the Feasibility of Essential Conversions in the MELiSSA Loop [PDF]

open access: yes, 2019
To sustain human deep space exploration or extra-terrestrial settlements where no resupply from the Earth or other planets is possible, technologies for in situ food production, water, air, and waste recovery need to be developed.

Ammonia-oxidizing archaea have more important role than ammonia-oxidizing bacteria in ammonia oxidation of strongly acidic soils [PDF]

open access: yesThe ISME Journal, 2011
Abstract Increasing evidence demonstrated the involvement of ammonia-oxidizing archaea (AOA) in the global nitrogen cycle, but the relative contributions of AOA and ammonia-oxidizing bacteria (AOB) to ammonia oxidation are still in debate. Previous studies suggest that AOA would be more adapted to ammonia-limited oligotrophic conditions,

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

open access: yes, 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

Cultivation of Autotrophic Ammonia-Oxidizing Archaea from Marine Sediments in Coculture with Sulfur-Oxidizing Bacteria

open access: yesApplied and Environmental Microbiology, 2010
The role of ammonia-oxidizing archaea (AOA) in nitrogen cycling in marine sediments remains poorly characterized. In this study, we enriched and characterized AOA from marine sediments. Group I.1a crenarchaea closely related to those identified in marine

Competition between Ammonia-Oxidizing Archaea and Bacteria from Freshwater Environments

open access: yesApplied and Environmental Microbiology, 2021
Nitrification is an important process in the global nitrogen cycle. The first step, ammonia oxidation to nitrite, can be carried out by ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB).

Relating Anaerobic Digestion Microbial Community and Process Function [PDF]

open access: yes, 2016
Anaerobic digestion (AD) involves a consortium of microorganisms that convert substrates into biogas containing methane for renewable energy. The technology has suffered from the perception of being periodically unstable due to limited understanding of ...

Bioaugmentation of nitrifying bacteria in up-flow biological aerated filter's microbial community for wastewater treatment and analysis of its microbial community

open access: yesScientific African, 2021
Bioaugmentation is a bioremediation approach involving the seeding of the competent microbial consortia to improve nitrogen removal from wastewater. The discharge of nitrogen-saturated wastewater into freshwater results in cultural eutrophication and ...

Metagenomic Evidence for the Presence of Comammox Nitrospira-Like Bacteria in a Drinking Water System

open access: yesmSphere, 2016
We report metagenomic evidence for the presence of a Nitrospira-like organism with the metabolic potential to perform the complete oxidation of ammonia to nitrate (i.e., it is a complete ammonia oxidizer [comammox]) in a drinking water system.

Metabolic network analysis reveals microbial community interactions in anammox granules. [PDF]

open access: yes, 2017
Microbial communities mediating anaerobic ammonium oxidation (anammox) represent one of the most energy-efficient environmental biotechnologies for nitrogen removal from wastewater.
