A review on nirS-type and nirK-type denitrifiers via a scientometric approach coupled with case studies

Environmental Science Processes & Impacts, Journal Year: 2021, Volume and Issue: 24(2), P. 221 - 232

Published: Dec. 30, 2021

The denitrification process plays an important role in improving water quality and is a source/sink of nitrous oxide to the atmosphere. second rate-limiting step catalyzed by two enzymes with different structures unrelated evolutionary relationships, namely, Cu-type nitrite reductase encoded nirK gene cytochrome cd1-type nirS gene. Although some relevant reviews have been published on denitrifiers, most these do not include statistical analysis, compare communities in-depth. However, systematic study nirS-type nirK-type denitrifying their response environmental factors ecosystems needed. In this review, scientometric approach combined case studies was used denitrifiers. demonstrated that Pseudomonas, Paracoccus, Thauera are frequently mentioned while Pseudomonas Bradyrhizobium top Among various factors, concentrations nitrite, nitrate carbon sources were widely reported can influence abundance structure communities.

N2O Emission and Nitrification/Denitrification Bacterial Communities in Upland Black Soil under Combined Effects of Early and Immediate Moisture

Agriculture, Journal Year: 2022, Volume and Issue: 12(3), P. 330 - 330

Published: Feb. 25, 2022

Soil moisture is the major factor influencing microbial properties and nitrous oxide (N2O) production. Agricultural soils can be probed under wetting, wet/dry alternating, constant conditions to evaluate combined effects of early (previous) immediate (current) on N2O emission nitrification/denitrification. In view water history upland black soil, five regimes comprising different antecedent present holding capacity (WHC) levels were set up in microcosm study. The 20% WHC was adopted as initial legacy moisture, while three statuses include WHC, dry-wet cycle, incremental moisture. Quantitative PCR 16S rRNA amplicon sequencing used assess impact current previous bacterial community composition abundance nitrification/denitrification genes (amoA, nirS, nosZ); soil physicochemical properties, monitored. production nitrifying-denitrifying communities influenced by pattern cycle. communities, especially members β-/γ-Proteobacteria, Bacteroidetes Gemmatimonadetes, important explaining variation key taxonomic groups response alteration, e.g., Acidobacteria, Sphingobacteriia, Deltaproteobacteria, Methylobacterium, Gemmatimonas Pseudarthrobacter, etc., also highlighted. nitrate, ammonium nitrogen, emission, mineralization profoundly impacted showed statistically significant correlation with specific genera; nitrite/nitrate reduction could boosted high Both nitrifier denitrification heterotrophic enhanced substantially when increased above 60% WHC. These findings help mode from well associated impacts both fertility global environment.
