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

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

Phylogenetic analysis reveals an ancient gene duplication as the origin of the MdtABC efflux pump. [PDF]
, 2020 The efflux pumps from the Resistance-Nodulation-Division family, RND, are main contributors to intrinsic antibiotic resistance in Gram-negative bacteria. Among this family, the MdtABC pump is unusual by having two inner membrane components.

The Isolation of Nitrosomonas europaea in Pure Culture [PDF]
Journal of General Microbiology, 1950 SUMMARY: Nitrosomonas europaea (Winogradsky) was isolated in pure culture from Rothamsted soil. The method used entailed: (1) building up the population of nitrifiers in enrichment cultures; (2) removal of the cells from the chalk in an enriched culture with a stream of carbon dioxide; (3) picking colonies from poured silica gel plates.
