soil metagenome
The primary goal of this study is to investigate the changes in soil microbial community structure after remediating uranium-contaminated soil for 50 days by adding a synthetic microbial community. The soil samples were collected from the farmland at the back mountain of Southwest University of Science and Technology, specifically from the plow layer with a depth of 0-15 cm. Uranium contamination in soil poses serious threats to ecological environment security and human health, and microbial remediation has been recognized as an efficient, environmentally friendly and low-cost technology for the remediation of heavy metal-contaminated soil. By analyzing the dynamic changes of microbial communities in the remediated uranium-contaminated soil, this study aims to clarify the response characteristics of soil microorganisms to the addition of synthetic microbial communities, provide theoretical basis and technical support for optimizing the microbial remediation strategy of uranium-contaminated soil, and further promote the practical application of synthetic microbial communities in the remediation of heavy metal-contaminated soil.
