To develop sustainable antibiotics, two different approaches (subprojects) are applied within PharmCycle: First, a re-design of the existing antibiotics with chemical and in silico methods (“Benign by Design”). Second, sustainable peptide-based antibiotics are produced with biotechnological methods. In the second step, the environmental risk assessment for antibiotics in the framework of the authorization process and for monitoring purposes is improved. There is a lack of data for the environmental risk assessment of antibiotics on the European market. With more transparency of these data, the environmental risk assessment for active substances and for the class of antibiotics can be improved. The aim is to increase the data availability by applying the Aarhus convention and by providing legal access to environmental information. Beside other shortages in the environmental risk assessment required by the European legislation, the effects of antibiotics directly applied in marine aquacultures are not assessed by marine prokaryotic test systems. Therefore, a marine cyanobacteria test was developed, which is more sensitive to selected priority antibiotics than the marine eukaryotic algae test (DIN EN ISO 10253) required by the European Medicines Agency. Marine cyanobacteria are of high importance for the nitrogen cycle and primary production. Moreover, they seem to play an important role with respect to climate change. To reduce the emission of antibiotics used as human pharmaceutical products to the aquatic environment, the third step focusses on the main pathway, the wastewater. Investigations to improve the wastewater treatment of priority antibiotics and sustainable antibiotics are conducted by a combination of methods: activated sludge units, activated carbon adsorption, and membrane filtration systems.
