Overview

Randomized trial investigates microbial responses to TNT in sediment, suggesting potential for bioremediation.

Key Points

  • To characterize the taxonomic and functional potential of microbial communities in TNT-contaminated sediments.
  • Characterization of sediment microbiomes using 16S rRNA sequencing and shotgun metagenomics.
  • Targeted analysis through GC-MS/MS with laboratory enrichment experiments.
  • Assessment of community shifts, enzyme classes, and gene enrichment related to TNT transformation.
  • Sediment communities showed increased Proteobacteria representation, particularly Haliaceae and Rhodobacteraceae.
  • Enrichment of oxidoreductases and stress-related enzymes, including glutathione S-transferases, was observed.
  • Laboratory enrichment confirmed TNT removal and the presence of N-ethylmaleimide reductase, supporting its role in TNT transformations.
