Dissimilatory nitrate reduction翻译
WebDissimilatory nitrate reduction to ammonium (DNRA) as a nitrogen link, versus denitrification as a sink in a shallow estuary (Laguna Madre/Baffin Bay, Texas). Marine … WebThe competition between DNF and DNRA controls the dissimilatory reduction pattern and the final fate of nitrate in aquatic ecosystems. In this study, DNF and DNRA processes at the sediment-water interface (SWI) in Lake Kuilei (a shallow freshwater lake in Lake Taihu basin) were studied by using the stable nitrogen isotope tracing method.

WebLike nitrate reduction, reduction of sulfate also takes place by the assimilatory and dissimilatory pathways. Plants, fungi and bacteria, in general, are able to use sulfate as source of the essential element, sulfur, which is used in the synthesis of sulfur-containing amino acids, like cysteine, and methionine. Webnium, sulphate reduction produces free sulphide, and nitrate reduction produces N 2 gas. Nitrate reduction has been extended (see below) to account for DNRA and is the main subject of this paper. Model equations are similar to those in Table 2 of Kelly-Gerreyn et al. (1999) but have been modified to take in to account temperature changes. To do ...
WebJan 1, 1996 · A total of 28 nitrate-reducing bacteria were isolated from marine sediment (Mediterranean coast of France) in which dissimilatory reduction of nitrate to ammonium (DRNA) was estimated as 80% of the overall nitrate consumption. Thirteen isolates were considered as denitrifiers and ten as dissimilatory ammonium producers.
