Abstract

Nitrous oxide (N2O) is a powerful greenhouse gas emitted from wastewater treatment, as well as natural systems, as a result of biological nitrification and denitrification. While denitrifying bacteria can be a significant source of N2O, they can also reduce N2O to N2. More information on the kinetics of N2O formation and reduction by denitrifying bacteria is needed to predict and quantify their impact on N2O emissions. In this study, kinetic parameters were determined for Paracoccus pantotrophus, a common denitrifying bacterium. Parameters included the maximum specific reduction rates, [Formula: see text], growth rates, [Formula: see text], and yields, Y, for reduction of NO3(-) (nitrate) to nitrite (NO2(-)), NO2(-) to N2O, and N2O to N2, with acetate as the electron donor. The [Formula: see text] values were 2.9 gN gCOD(-1) d(-1) for NO3(-) to NO2(-), 1.4 gN gCOD(-1) d(-1) for NO2(-) to N2O, and 5.3 gN gCOD(-1) d(-1) for N2O to N2. The [Formula: see text] values were 2.7, 0.93, and 1.5 d(-1), respectively. When N2O and NO3(-) were added concurrently, the apparent (extant) kinetics, [Formula: see text], assuming reduction to N2, were 6.3 gCOD gCOD(-1) d(-1), compared to 5.4 gCOD gCOD(-1) d(-1) for NO3(-) as the sole added acceptor. The [Formula: see text] was 1.6 d(-1), compared to 2.5 d(-1) for NO3(-) alone. These results suggest that NO3(-) and N2O were reduced concurrently. Based on this research, denitrifying bacteria like P. pantotrophus may serve as a significant sink for N2O. With careful design and operation, treatment plants can use denitrifying bacteria to minimize N2O emissions.

Attention Score in Context

This research output has an Altmetric Attention Score of 3. 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 04 October 2016.
All research outputs
#3,535,015
of 8,472,367 outputs
Outputs from AMB Express
#73
of 517 outputs
Outputs of similar age
#98,831
of 253,774 outputs
Outputs of similar age from AMB Express
#10
of 63 outputs
Altmetric has tracked 8,472,367 research outputs across all sources so far. This one has received more attention than most of these and is in the 57th percentile.
So far Altmetric has tracked 517 research outputs from this source. They receive a mean Attention Score of 2.2. This one has done well, scoring higher than 85% 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 253,774 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 60% of its contemporaries.
We're also able to compare this research output to 63 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 84% of its contemporaries.
