Cd distribution and phenanthrene degradation pathways in Cd-tolerant and phenanthrene-degrading bacteria under elevated Cd concentrations: A low-toxicity convergence strategy

Key Points

• Phenanthrene degradation pathways were prominent under elevated cd concentrations, enhancing bacterial resilience.
• Cd-tolerant bacteria demonstrated effective degradation of phenanthrene, achieving a removal rate of 75% in 48 hours.
• Analysis included a comparative evaluation of cd distribution across different bacterial strains, revealing significant variability.
• Findings highlight potential environmental applications, suggesting strategies for bio-remediation of contaminated sites.
