Dominant hydrocarbon degraders Pseudoalteromonas sp., Ruegeria sp., Exiguobacterium sp. and Acinetobacter sp. isolated from deep sea sediments were identified using biochemical characterization and 16S rRNA sequencing analysis. Biodegradation studies evinced the capability of these strains in effectively utilizing the SE oil as carbon source. The FTIR spectra and GC–MS analysis confirmed the breakdown of aromatic and aliphatic hydrocarbons, and accumulation of degraded metabolites. The rapid utilization and degradation of complex hydrocarbons by this novel deep sea bacterial consortium emphasizes their potential application for bioremediation process in extreme marine environments.
