A two-lane mechanism for selective biological ammonium transport
eLife, 2020 The transport of charged molecules across biological membranes faces the dual problem of accommodating charges in a highly hydrophobic environment while maintaining selective substrate translocation.

Comparative Proteomics of Three Species of Ammonia-Oxidizing Bacteria
Frontiers in Microbiology, 2018 Ammonia-oxidizing bacteria (AOB) are important members of terrestrial, marine, and industrial microbial communities and play a fundamental role in the Nitrogen cycle within these systems.

Characterization of the ferrioxamine uptake system of Nitrosomonas europaea [PDF]
Microbiology, 2007 The chemolithoautotroph Nitrosomonas europaea has two genes predicted to encode outer-membrane (OM) ferrioxamine transporters. Expression of the ferrioxamine uptake system required induction, as shown by the shorter lag phase in ferrioxamine-containing cultures when ferrioxamine-exposed cells were used as an inoculum.

Biological nitrification inhibition by rice root exudates in two different soils of Uruguay
Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2021 Rice root exudates can control nitrification by releasing biological nitrification inhibitors (BNIs), reducing nitrogen losses in agricultural soils. However, the inhibitory effect on nitrification and the abundance of ammonia oxidisers in different soil

eLife, 2020 In order to enter a cell, an ammonium ion must first dissociate to form an ammonia molecule and a hydrogen ion (a proton), which then pass through the cell membrane separately and recombine inside.

Biomass production from electricity using ammonia as an electron carrier in a reverse microbial fuel cell. [PDF]
PLoS ONE, 2012 The storage of renewable electrical energy within chemical bonds of biofuels and other chemicals is a route to decreasing petroleum usage. A critical challenge is the efficient transfer of electrons into a biological host that can covert this energy into

Frontiers in Molecular Biosciences, 2023 Introduction: Biological Nitrification Inhibition (BNI) is defined as the plant-mediated control of soil nitrification via the release of nitrification inhibitors. BNI of Brachiaria humidicola (syn. Urochloa humidicola) has been mainly attributed to root-
