| Abstract |
To recover a nitrogen resource from high-ammonia-nitrogen wastewater, two amphitrophic hydrogen-oxidizing bacteria (HOB), Paracoccus denitrificans Y5 and P. versutus D6, capable of nitrogen assimilation for single-cell protein (SCP) production were isolated. These two HOB strains could grow autotrophically with H2 as an electron donor, O2 as an electron acceptor, CO2 as a carbon source, and ammonia nitrogen (NH4+-N) as a nitrogen source. The cell molecular formulas of strains Y5 and D6 determined by autotrophic cultivation were C3.33H6.83O2.58N0.77 and C2.87H5.34O3.17N0.57, respectively. The isolated strains could synchronously remove NH4+-N and organic carbon and produce SCP via heterotrophic cultivation. The rates of removal of NH4+-N and soluble chemical oxygen demand reached 35.47 and 49.04%, respectively, for Y5 under mixotrophic cultivation conditions with biogas slurry as a substrate. SCP content of strains Y5 and D6 was 67.34-73.73% based on cell dry weight. Compared with soybean meal, the SCP of Y5 contained a variety of amino acids. |

Attention Score in Context
This research output has an Altmetric Attention Score of 20. 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 03 November 2022.
All research outputs
#1,570,230
of 23,025,074 outputs
Outputs from Applied Biochemistry and Biotechnology
#12
of 2,531 outputs
Outputs of similar age
#35,667
of 328,997 outputs
Outputs of similar age from Applied Biochemistry and Biotechnology
#1
of 28 outputs
Altmetric has tracked 23,025,074 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 93rd percentile: it's in the top 10% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 2,531 research outputs from this source. They receive a mean Attention Score of 3.2. This one has done particularly well, scoring higher than 99% 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 328,997 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 28 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 96% of its contemporaries.
