Structural and Functional Interrogation of Selected Biological Nitrogen Removal Systems in the United States, Denmark, and Singapore Using Shotgun Metagenomics

Frontiers in Microbiology, 2018
Conventional biological nitrogen removal (BNR), comprised of nitrification and denitrification, is traditionally employed in wastewater treatment plants (WWTPs) to prevent eutrophication in receiving water bodies.

Benthic Ammonia Oxidizers Differ in Community Structure and Biogeochemical Potential Across a Riverine Delta

Frontiers in Microbiology, 2015
Nitrogen pollution in coastal zones is a widespread issue, particularly in ecosystems with urban or agricultural watersheds. California’s Sacramento-San Joaquin Delta, at the landward reaches of San Francisco Bay, is highly impacted by both agricultural ...

Ammonia-oxidizing Bacteria in Aquaculture Pond

, 2002
The process of nitrification is highly dependent on the microbial activities and transformation, which is carried out by autotrophic nitrifiers in general, however some heterotrophic nitrifiers also can carry out the process. The diversity of autotrophic

A narrow bandgap Schottky heterojunction Fe2N/CeO2 microneedle triggering sonodynamic reactive oxygen species storm for drug‐resistance‐free skin fungal infection

BMEMat, EarlyView.
Inorganic sonosensitizers suffer from inefficient electron‐hole separation, rapid recombination, and wide bandgaps in anti‐fungal applications. We propose MN@Fe2N/CeO2 to directly eliminate fungi without drug resistance. Combining semiconductor CeO2's advantages with Fe2N's high work function and activity enables efficient Schottky heterojunctions ...

Ammonia-oxidizing archaea and complete ammonia-oxidizing bacteria in a municipal wastewater treatment plant [PDF]

, 2018
High levels of ammonia in aquatic environments can lead to eutrophication, oxygen depletion, and toxicity to aquatic animals. An important goal of municipal wastewater treatment plants (WWTPs) is to remove ammonia from human waste before the treated ...
