The widespread appearance of diclofenac as an emerging contaminant in the environment and its potential impact on living organisms is a matter of concern. Our current work uses proteomics and metabolomics to gain a better understanding of diclofenac biodegradation by the bacterial strain Raoultella sp. KDF8.
