Uranium contamination in soil poses a significant environmental concern due to its potential toxic effects. Understanding the impact of uranium contamination on soil bacterial communities is crucial for assessing the ecological consequences and developing effective remediation strategies. This study aimed to investigate the impact of uranium contamination on soil bacterial communities by identifying and characterizing bacterial species present in uranium-contaminated soil samples. The analysis involved the use of advanced molecular techniques to identify bacterial species and assess their diversity and composition. Additionally, functional traits and potential uranium tolerance mechanisms of the identified bacterial species were examined. The findings provide valuable insights into the response of soil bacterial communities to uranium contamination and contribute to the development of sustainable remediation strategies for uranium-contaminated sites.
