Efficient PAHs biodegradation by a bacterial consortium at flask and bioreactor scale

▸ Bacillus pumilus and Staphylococcus warneri are efficient PAHs biodegraders. ▸ Operation in stirred tank bioreactor led to 100% of PHE, PYR and BaA removal. ▸ Metabolic route to degrade PHE, PYR and BaA was elucidated. ▸ Logistic and Luedeking and Piret equations were used to suitably model the process.
