However, its improper use and disposal have caused severe soil pollution, which potentially leads to detrimental ecological and environmental impacts. Bioremediation is an environmentally friendly approach that employs micro-organisms to degrade or transform pollutants into less toxic forms. Therefore, isolation and identification of benomyl-degrading bacteria and their application for soil remediation are of great significance.Objectives:The objectives of this study are to isolate and identify a benomyl-degrading bacterial strain from contaminated soil and evaluate its ability to remediate benomyl polluted soil.Methods:1. Soil sample collection and preparation2. Bacterial isolation and screening for benomyl-degrading ability3. Molecular identification of the selected bacterial strain4. Effect of temperature, pH and initial benomyl concentration on bacterial growth and degradation5. Remediation of benomyl contaminated soil by bacterial strain application6. Analyze the effectiveness of bioremediation using chemical analyses of soil samplesExpected Outcome:This study is expected to identify and isolate a bacterial strain capable of degrading benomyl in soil. The optimal 精品文档---下载后可任意编辑conditions for its growth and degradation will be determined. The bacterial strain will be applied for the remediation of benomyl contaminated soil. The effectiveness of the bioremediation process will be evaluated by analyzing the changes in chemical composition of the soil.Significance:This study provides a cost-effective and environmentally friendly method for the remediation of benomyl contaminated soil. The identified bacterial strain can be potentially applied at a larger scale to restore polluted farmland, improve soil quality and productivity, and protect the ecosystem.
