Resumen:
Oily residues that are generated in normal ship operation are considered hazardous wastes. A biodegradation assay with autochthonous
microbiota of Bilge Waste Oily Phase (BWOP) was performed in a bioreactor under controlled conditions. Petroleum, diesel oil, and
PAH degraders were isolated from bilge wastes. These bacteria belong to the genus Pseudomonas and are closely related to Pseudomonas
stutzeri as shown by 16S rDNA phylogenetic analysis. The indigenous microbial community of the bilge waste was capable of biodegrading
the BWOP (1% v/v) with biodegradation eYciencies of 70% for hexane extractable material (HEM), 68% for total hydrocarbons (TH)
and 90% for total aromatics hydrocarbons (TA) in 14 days. Solid phase microextraction (SPME) was successfully applied to evaluate
hydrocarbon evaporation in a control experiment and demonstrated a mass balance closure of 88%. The SPME and biodegradation
results give useful information to improve and scale up the process for BWOP treatment.
