Can the transfer of veterinary antibiotics into soil be reduced by biogas plants?

Aim of the project is to understand whether antibiotics are diminished during the fermentation process, i.e. to what extent the fermentation gas technology could contribute to prevent contamination of the environment with these active substances. For this reason the behaviour of tetracyclines and chinolones in the fermentation process will be studied in both laboratory as well as on-farm conditions. They might also disturb the fermentation process of the biological gas facilities due to antimicrobial activity which would end up with less gas production and as a consequence less energy generation. Furthermore, optimal storage time will be obtained by the calculation of the half times of the investigated substances.
