Exploring Bacterial Resilience to Uranium Contamination: Species Identification and Characterization
Abstract
Uranium contamination in soil poses significant environmental and ecological risks, affecting microbial communities and their functions. This study explores the resilience of bacterial species in uranium-contaminated environments by identifying and characterizing affected microbial populations. Soil samples from uranium-impacted sites were analyzed using culture-dependent and molecular techniques to assess bacterial diversity, resistance mechanisms, and potential bioremediation capabilities. The results indicate the presence of uranium-tolerant bacteria, including species with metal-resistant genes and bioaccumulation properties. Understanding these adaptive mechanisms provides insights into microbial responses to heavy metal stress and informs bioremediation strategies for uranium-contaminated ecosystems.
