Anaerobic Growth and Denitrification among Different Serogroups of Soybean Rhizobia.

Applied and environmental microbiology

van Berkum P, Keyser HH.
PMID: 16346767
Appl Environ Microbiol. 1985 Apr;49(4):772-7. doi: 10.1128/aem.49.4.772-777.1985.

We screened soybean rhizobia originating from three germplasm collections for the ability to grow anaerobically in the presence of NO(3) and for differences in final product formation from anaerobic NO(3) metabolism. Denitrification abilities of selected strains as free-living bacteria...

Nitrous oxide reduction in nodules: denitrification or n(2) fixation?.

Applied and environmental microbiology

Coyne MS, Focht DD.
PMID: 16347344
Appl Environ Microbiol. 1987 May;53(5):1168-70. doi: 10.1128/aem.53.5.1168-1170.1987.

Detached cowpea nodules that contained a nitrous oxide reductase-positive (Nor) rhizobium strain (8A55) and a nitrous oxide reductase-negative (Nor) rhizobium strain (32H1) were incubated with 1% N(2)O (95 atom% N) in the following three atmospheres: (i) aerobic with C(2)H(2)...

Expression of nitrous oxide reductase from Pseudomonas stutzeri in transgenic tobacco roots using the root-specific rolD promoter from Agrobacterium rhizogenes.

Wan S, Johnson AM, Altosaar I.
PMID: 22423324
Ecol Evol. 2012 Feb;2(2):286-97. doi: 10.1002/ece3.74.

The nitrous oxide (N(2)O) reduction pathway from a soil bacterium, Pseudomonas stutzeri, was engineered in plants to reduce N(2)O emissions. As a proof of principle, transgenic plants expressing nitrous oxide reductase (N(2)OR) from P. stutzeri, encoded by the nosZ...

Denitrification is a respiratory process that produces nitrous oxide as an intermediate, which may escape to the atmosphere before its reduction to dinitrogen through the nitrous oxide reductase NosZ. In this work, the denitrification process carried out by

Reduction in denitrification activity in field soils exposed to long term contamination by 2,4,6-trinitrotoluene (TNT).

FEMS microbiology ecology

Siciliano SD, Roy R, Greer CW.
PMID: 10779620
FEMS Microbiol Ecol. 2000 Apr 01;32(1):61-68. doi: 10.1111/j.1574-6941.2000.tb00699.x.

Terrestrial sites contaminated with 2,4,6-trinitrotoluene (TNT) are a widespread and persistent problem and often contain non-vegetated areas with TNT concentrations well in excess of 1000 mg kg(-1). In this study, we examined the effect of TNT on denitrification activity...

Nitrous Oxide Emissions from Ephemeral Wetland Soils are Correlated with Microbial Community Composition.

Frontiers in microbiology

Ma WK, Farrell RE, Siciliano SD.
PMID: 21712943
Front Microbiol. 2011 Jun 10;2:110. doi: 10.3389/fmicb.2011.00110. eCollection 2011.

Nitrous oxide (N(2)O) is a greenhouse gas with a global warming potential far exceeding that of CO(2). Soil N(2)O emissions are a product of two microbially mediated processes: nitrification and denitrification. Understanding the effects of landscape on microbial communities,...

Denitrification and environmental factors influencing nitrate removal in Guaymas Basin hydrothermally altered sediments.

Frontiers in microbiology

Bowles MW, Nigro LM, Teske AP, Joye SB.

Front Microbiol. 2012 Oct 25;3:377. doi: 10.3389/fmicb.2012.00377. eCollection 2012.

We measured potential nitrate removal and denitrification rates in hydrothermally altered sediments inhabited by Beggiatoa mats and adjacent brown oil stained sediments from the Guaymas Basin, Gulf of California. Sediments with Beggiatoa maintained slightly higher rates of potential denitrification...
