Abstract
Methane oxidation by soil microorganisms is crucial in mitigating greenhouse gas emissions. This study investigated methane oxidation potential across four distinct soil environments through standardized laboratory enrichment cultures. Soil samples were collected from landfill-cover soils, rice fields, cattle farms, and pond sediments, with environmental parameters monitored to understand their influence on oxidation rates and efficiencies. Using gas chromatography analysis, we quantified methane oxidation under controlled conditions. Statistical analysis revealed significant differences in oxidation rates across soil types. Landfill cover soils exhibited the highest oxidation rate of 0.39 μmol-CH₄/g-soil dry weight/h and efficiency of 66.5 %. Pond sediments, cattle farm soils, and rice field soils followed with rates of 0.29, 0.28, and 0.27 μmol-CH₄/g-soil dry weight/h, respectively. Oxidation efficiencies for these environments ranged from 46.1% to 48.4%. pH and organic matter content showed strong positive correlations with oxidation rates across all soil types, while environmental moisture content effects varied. The superior performance of landfill soils was attributed to optimal environmental conditions and stable substrate availability. This analysis revealed significant potential for enhancing oxidation efficiencies: landfill soils from 66.5% to 75-85%, rice fields from 46.1% to 60-70%, cattle farms from 47.0% to 55-65%, and pond sediments from 48.4% to 60-75%. Implementing optimized management strategies could reduce methane emissions by 70-90% in landfills, 30-50% in agricultural systems, and 40-60% in aquatic environments compared to current practices. This study highlights the substantial potential for enhancing biological methane oxidation across diverse ecosystems and emphasizes the need for targeted management approaches to optimize methane mitigation strategies.
