•Tripolium pannonicum was used as biofilter to uptake the antibiotic sulfadimidine (SDI).•T. pannonicum was able to grow in a SDI concentration up to 10mg·L−1.•SDI in the culture medium was decreased by T. pannonicum and further during anaerobic digestion.•Fermentation of T. pannonicum has led to biogas yields up to 534mL·g−1 VS.•Biomass containing SDI did not adversely affect the biogas production. This project analyses the uptake and biodegradation of the antimicrobial sulfadimidine (SDI) from the culture medium and up to the anaerobic digestion. Tripolium pannonicum was grown under hydroponic conditions with different concentrations of SDI (0, 5 and 10mg·L−1) and the fresh biomass, containing different amounts of SDI taken up, was used as substrate for biogas production. SDI was analyzed by liquid chromatography coupled to positive ion electrospray mass spectrometry (ESI LC–MS). Based on the findings, T. pannonicum is able to uptake SDI. The more SDI is in the culture medium, the higher the SDI content in the plant tissue. According to this study, it is possible to produce high yields of biogas using biomass of T. pannonicum containing SDI and at the same time biodegradation of SDI is carried out. The highest specific biogas yield is obtained using shoots as substrate of the plants cultivated at 5mg·L−1 SDI.
