Polycyclic aromatic hydrocarbons (PAHs), including phenanthrene, are
commonly found as pollutants in soils, estuarine, and sediments, as
well as in terrestrial and other aquatic ecosystems. In this context, the
phenanthrene-degrading bacteria were isolated and characterized in
contaminated mangrove surface sediment, on the coast of Thane Creek,
Mumbai, India by enrichment method, using phenanthrene as the sole
source of carbon and energy. The phylogenetic diversity of the isolates
were evaluated by 16S rRNA gene analysis and characterized as Bacillus
mojavensis strain KSS001, Bacillus firmus strain KSS002, Bacillus flexus
strain KSS003, Bacillus vietnamensis strain KSS004, and Bacillus amyloliquefaciens
strain KSS005. Each isolate was grown on the phenanthrene
up to 100 mg/L and the biodegradation ability was evidenced using a
gas chromatography–flame ionization detector. Further, the mean value
of phenanthrene degradation by 5 bacterial isolates after incubation in
mineral salt medium for 7 days was 63% at 100 mg/L. The study reports
that mangrove sediments of Thane Creek, Mumbai, contain a diverse
population of phenanthrene-degrading bacteria that have the potential
and capability to degrade PAHs contaminated sites, and are consequently
recommended for bioremediation.
