Bacterial Mitigation of Nitrous Oxide in Soil and Liquid Systems

257 data points from 34 independent studies were integrated via meta-analysis to assess bacterial N2O mitigation. The study, authored by Shengsen Zhou and published in 2026, quantifies mitigation effectiveness across soil-based and liquid culture environments. It identifies key functional bacterial genera and explores underlying molecular mechanisms.

Use Cases

• Compare N2O mitigation extent (68.3% vs 42.9%) and reduction rates (3.68 vs 1.78 μmol·h−1·g−1) between liquid culture and soil-based systems.
• Analyze the influence of environmental factors like oxygen level (microoxic vs anoxic), pH (acidic vs neutral), and cultivation duration on mitigation effectiveness.
• Identify key functional bacterial genera (Bradyrhizobium and Azospira) associated with N2O reduction in different incubation systems.
• Explore the regulatory role of specific metabolic pathways (denitrification, dissimilatory nitrate reduction, nitrogen fixation) using functional gene analysis data.

Strengths

• Integrated 257 quantitative data points from 34 independent studies.
• Provides specific, comparable metrics for mitigation extent and reduction rates across two system types.
• Includes analysis of environmental factors (oxygen, pH, duration) and functional gene pathways.

Limitations

• Underlying raw experimental data is not provided, only the synthesized meta-analysis results.
• The 6.3 MB file contains a document (DOCX) summarizing the study, not a structured dataset for direct computational analysis.
• Spatial coverage of the source studies is not specified, potentially limiting geographic insights.
