Genomic Personalities of Dehalococcoides Subspecies and Dehalogenimonas Illuminate Complete Trichloroethene Dechlorination in High-Salt Conditions

This study aims to elucidate the molecular adaptations of Dehalococcoides and Dehalogenimonas to high salinity disturbances and their impact on trichloroethylene (TCE) dechlorination. Specifically, the research investigates the genomic and functional differences between various subspecies of these microorganisms under extreme saline conditions, which is crucial for understanding their environmental resilience and efficacy in bioremediation processes. By conducting comparative genomics and analyzing the differential expression of key genes involved in TCE dechlorination, this study seeks to uncover the underlying mechanisms that enable these bacteria to thrive and maintain their dechlorinating activities in high-salinity environments. The findings are expected to provide significant insights into optimizing bioremediation strategies for saline-impacted sites, enhancing the practical applications of these microorganisms in the cleanup of TCE-contaminated environments.
