Sentence examples for nitrate respiration from inspiring English sources
Nar, together with the related enzyme formate dehydrogenase (Fdh-N), is a key enzyme in the generation of proton motive force across the membrane in Escherichia coli nitrate respiration.
The model included the following: microbiological processes —exogenous and endogenous nitrate respiration coupled to microbial growth and decay; geochemical processes —precipitation or dissolution of calcite; and isotopic fractionation —δ15N-NO3−, δ18O-NO3−, and δ13C-DIC, incorporating the full δ13C isotope geochemistry involved in EIB.
The most appropriate justification for this behavior of W Nar is that P. aerophilum needs to support its growth by nitrate respiration even when the tungsten concentration in the environment is high; the same was concluded experimentally [21].
Marc et al. [102] sequenced over 70% of the genome of Beggiatoa from the surface of marine sediment and confirmed the chemolithoautotrophic physiology via investigating the pathway for sulfur oxidation, oxygen and nitrate respiration, and carbon metabolism.
Some soil bacteria can use nitrate respiration under aerobic conditions (Carter et al. 1995), and Halomonas type bacterium Halomonas elongata can reduce nitrate and grow anaerobically (Vreeland et al. 1980).
Nitrite is a toxic by-product of nitrate respiration.
In enterobacteria, NirBD is required to detoxify nitrite produced intracellularly during nitrate respiration [25].
This includes both reactions that remove nitrogen from ecosystems (such as nitrate-based respiration and denitrification) as well as processes that introduce nitrogen (such as nitrate assimilation and nitrogen fixation).
The membrane-bound nitrate reductase, encoded by NarGHI operon, can be found in many nitrate-respiring and denitrifying bacteria and functions as the generator of proton motive force by coupling nitrate reduction in respiration.
Most of these features relate to the nitrate and nitrite respiration.
61 In case of oxygen deprived growth conditions for E. coli, anaerobic respiration nitrate is the preferred electron acceptor.
