  abstract = {{L}arge pilot scale bioremediation approaches were implemented for the treatments of oily sludge ({OS}) characterised by alkaline p{H} (p{H} > 9), high concentration of metals (3% dry weight) and high total petroleum hydrocarbons content ({TPH}) rangingbetween 22,000 and 67,300 mg kg -1 from a {T}unisian petroleum refinery. {T}he treatments included bioaugmentation and biostimulation approaches with autochthonous isolated bacterial strains and consortia. {C}hemical, microbial, and ecotoxicological analyses were performed over a period of 180 days incubation. {T}he bioremediation treatments favoured the development of {P}roteobacteria, {F}irmicutes and {B}acteroidetes following an ecological succession of specialist bacterial groups, first associated to hydrocarbon degradation (e.g. {M}arinobacter and {A}lcanivorax) that resulted in a greater extent of {TPH}-degradation (up to 80%), and the selection of metal resistant bacteria including {H}yphomonas, {P}haeobacter, and {D}esulfuromusa. {T}he best performances were obtained when bioaugmentation and biostimulation were combined. {O}ver 90% of the {TPH} initial concentration was degraded over 180 days, which was accompanied with a 3-fold reduction of ecotoxicity. {O}ur study demonstrates the efficacy of large pilot scale bioremediation of highly contaminated oily sludge, providing the evidence that the management of autochthonous microbial communities is of paramount importance for the success of the bioremediation process.},
