Abstract
Enrofloxacin degradation by ionizing radiation and cupriavidus metallidurans resistance were investigated. Analysis by nuclear magnetic resonance spectroscopy (NMR) and fourier transform infrared spectroscopy (FTIR) were performed to monitor changes in metabolic profiles of enrofloxacin after irradiation at 50 KGy. The obtained result confirms that ionizing radiation process leads to the cleavage of three aromatic cycle, the cyclopropyl and the disparition of carboxyl acid function flowed by the formation of NH functions and aliphatic hydrocarbons chain. In addition, irradiation process is able to reduce the biological inhibition activity of enrofloxacin and leads to the growth of cupriavidus metallidurans at high concentration of enrofloxacin (1mg/ml). Consequently, the combined processes of ionizing radation followed by microbial removal of enrofloxacin seem to be the best solution for the treatment of effluents containing enrofloxacin antibiotics.
