Respiratory Nitrate Ammonification byShewanella oneidensisMR-1 [PDF]
Journal of Bacteriology, 2007 ABSTRACTAnaerobic cultures ofShewanella oneidensisMR-1 grown with nitrate as the sole electron acceptor exhibited sequential reduction of nitrate to nitrite and then to ammonium. Little dinitrogen and nitrous oxide were detected, and no growth occurred on nitrous oxide.

Effect of Ammonia Pretreatment on Enzymatic Sugar Production from Corn Stover
Shipin gongye ke-ji, 2023 To make comprehensive use of maize stover, cellulase degradation of maize stover was accelerated. In this paper, maize straw was used as raw material, and reducing sugar yield was the main indicator.

Ammonification in air-dried tropical lowland Histosols [PDF]
Soil Biology and Biochemistry, 1981 The NH4+-N content of fresh organic soils sampled from wetland rice areas in the Philippines was 5-10 mg kg-1, and remained constant during anaerobic incubation for 8 weeks. Air dried soils contained 50-200 mg NH4+-N kg-1 before incubation began, indicating that ammonification took place during air drying; during subsequent incubation of air dried ...

Spatial variations in sedimentary N-transformation rates in the North Sea (German Bight) [PDF]
Biogeosciences, 2020 In this study, we investigate the role of sedimentary N cycling in the southern North Sea. We present a budget of ammonification, nitrification and sedimentary NO3- consumption and denitrification in contrasting sediment types of the German Bight ...

Effect of long-term changes in soil chemistry induced by road salt applications on N-transformations in roadside soils [PDF]
, 2008 Of several impacts of road salting on roadside soils, the potential disruption of the nitrogen cycle has been largely ignored. Therefore the fates of low-level ammonium-N and nitrate-N inputs to roadside soils impacted by salting over an extended period (
