| Popis: | Marine oil pollution can result in the persistent presence of weathered oil. Currently, removal of weath- ered oil is reliant on chemical dispersants and physical removal, causing further disruption. In contrast few studies have examined the potential of an environmentally sustainable method using a hydrocarbon degrading microbial community attached to a carrier. Here, we used a tank mesocosm system (50 l) to follow the degradation of weathered oil (10 g l-1) using a bacterial consortium mobilised onto different carrier materials (alginate or shell grit). GCMS analysis demonstrated that the extent of hydrocarbon deg- radation was dependent upon the carrier material. Augmentation of shell grit with nutrients and exoge- nous hydrocarbon degraders resulted in 75 ± 14% removal of >C32 hydrocarbons after 12 weeks compared to 20 ± 14% for the alginate carrier. This study demonstrated the effectiveness of a biostimulated and bio- augmented carrier material to degrade marine weathered oil. Refereed/Peer-reviewed |
