Regeneration of ion exchange resins with NaCl produces brine containing high concentrations of nitrate that can be difficult to remove using standard biological, physical, or chemical technologies. In this study. Halomonas campisalis (ATCC #700597) (Mormile et al., 1999) was shown to completely reduce nitrate at 125 g/L NaCl and pH 9. This organism was also used in experiments to determine nitrate-reduction rates and biomass yields. Kinetic parameters were measured separately with glycerol, lactate. acetate, ethanol, and methanol. The specific nitrate-reduction rate coefficient was highest in cultures amended with acetate, while lactate and glycerol (a natural osmoticum in hypersaline environments) had lower reduction rates. No evidence of nitrate reduction was observed when ethanol or methanol was provided as an electron donor. Kinetic modeling provided values for nitrate and nitrite-reduction rate coefficients and for biomass yields. Measured rates and yields were similar to reported parameters obtained from non-halophilic nitrate-reducing cultures under low salt concentrations. Therefore, for highly saline solutions, the use of halophiles to selectively remove nitrate from these brines may represent a viable treatment option.
This research output has an Altmetric Attention Score of 9. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 19 June 2018.
All research outputs
#4,620,057
of 30,741,241 outputs
Outputs from Water Research
#1,315
of 13,818 outputs
Outputs of similar age
#11,559
of 157,509 outputs
Outputs of similar age from Water Research
#4
of 53 outputs
Altmetric has tracked 30,741,241 research outputs across all sources so far. Compared to these this one has done well and is in the 83rd percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 13,818 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.6. This one has done well, scoring higher than 88% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 157,509 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 89% of its contemporaries.
We're also able to compare this research output to 53 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 79% of its contemporaries.
