    • Abstract:
      Polycyclic aromatic hydrocarbons (PAHs), such as phenanthrene, are a type of organic pollutants that exist widely in the environment. Of the currently known degradation methods, bioremediation is a desirable and feasible option. A novel Diaphorobacter sp. Strain MNS-0 was isolated from saponification wastewater and showed the ability to degrade phenanthrene, fluorene, acenaphthene, anthracene, benzo[a]anthracene, or chrysene using phenanthrene as the sole carbon source. Gas chromatography mass spectroscopy analysis of catabolic intermediates indicates that phenanthrene degradation occurs through the phthalic acid pathway in strain MNS-0. Genome sequencing shows that strain MNS-0 has two plasmids and one chromosome containing a presumptive phenanthrene degradation gene cluster. Strain MNS-0 was able to completely degrade 100 mg/L phenanthrene within 40 h and tolerate up to 10 g/L NaCl at pH 9.0, while maintaining phenanthrene degradation activity. We thus propose that strain MNS-0 is an effective degrader for bioremediation of PAHs pollution, even in relatively harsh alkali environments such as saponification wastewater.
