Interaction between Enrofloxacin and the Extracellular Polymeric Substances from Platymonas Subcordiformis


Article Preview

Extracellular polymeric substances (EPS) in marine algae- Platymonas subcordiformis affected by enrofloxacin (ENR), the typical quinolone antibiotics released to the environment through different ways, was studied. A 3-dimension EEM (excitation –emission matrix) fluorescence spectroscopy was used to examine the interaction between EPS and ENR, and the fluorescent peaks A and B were detected, whose fluorescence intensity remarkably decreased with the increased ENR concentration. It was demonstrated that the interaction of EPS with ENR well fitted the modified Stern-Volmer. It was concluded that the presence of EPS in marine algae affected the transport and transform of antibiotics in aquatic environment.
