Florfenicol (FF) is an antibiotic largely used in aquaculture and its presence in their aqueous streams can affect the treatment process. Bacteria can play an important role in the cleanup of contaminated sites due to their ability to degrade an impressive variety of pollutants, using them as carbon and energy source. This study aimed to investigate the degradation of FF by a single bacterial strain, Labrys portucalensis F11. Biodegradation of FF was assessed in batch mode in the presence of a conventional carbon source and the bacterium was capable to remove ca. 80% of the FF supplied. When acetate was periodically added, although the cell growth was improved, no effect on the uptake of FF was observed but its defluorination was greatly enhanced.
