Water contamination is a growing environmental issue. Several harmful effects on human
health and the environment are attributed to nitrogen contamination of water sources …

Nitrogen is an essential component of all living organisms and the main nutrient limiting life
on our planet. By far, the largest inventory of freely accessible nitrogen is atmospheric …

Despite the fact that heterotrophic nitrification was identified more than 100 years ago, the
biochemistry of heterotrophic nitrifiers is poorly known and their contribution to nitrification in …

Methane is the final product of the anaerobic decomposition of organic matter. The
conversion of organic matter to methane (methanogenesis) as a mechanism for energy …

Largely removed from anthropogenic delivery of nitrogen (N), Antarctica has notably low
levels of nitrogen. Though our understanding of biological sources of ammonia have been …

Microbial communities mediating anaerobic ammonium oxidation (anammox) represent one
of the most energy-efficient environmental biotechnologies for nitrogen removal from …

Manganese is one of the most abundant elements on Earth. The oxidation of manganese
has long been theorized—yet has not been demonstrated,–—to fuel the growth of …

Sludge aggregation and biofilm formation are the most effective approaches to solve the
washout of anammox microorganisms. In this study, the structure and composition of EPS …

Nitrogen (N) is widely distributed in the lithosphere, hydrosphere, atmosphere and
biosphere. It is a basic component of every plant cell as well as microorganisms, as a …

Although using anammox communities for efficient wastewater treatment has attracted much
attention, the pure anammox bacteria are difficult to obtain, and the potential roles of …
