A biosensor based on Pseudomonas putida cells immobilized in an agarized culture medium was constructed for the purpose of determining traces of benzene in aqueous solutions using a classical gaseous diffusion amperometric oxygen electrode as transducer. After performing a complete electroanalytical characterization of the biosensor, the response to several benzene derivatives (toluene, chlorobenzene, nitrobenzene, ethylbenzene) was evaluated. The results obtained have been compared with those reported by other authors who used classical cellulose acetate filters for cell immobilization.
