My research activities are focused on the elimination of antibiotic resistance material within the multi-barrier concepts of drinking water resource protection. Wastewater treatment plants are not sufficiently equipped to fully eliminate antibiotics, some of their human metabolites and transformation products and hence discharge still considerable amounts into surface water bodies. Since surface water infiltrates naturally (bank filtration, BF) or engineered (managed aquifer recharge, MAR) into aquifers, these constituents pose a risk of antibiotic resistance propagation to groundwater as highly vulnerable drinking water resource.
We postulate that microbial processes of various redox zones play an essential role in the fate and transformation of groundwater-relevant antibiotics (sulfonamides, (fluoro)quinolones, macrolides) and their human metabolites. Hence, we are applying mass spectrometry methods to investigate their and the fate of their transformation products in the process sequence of bank filtration (aerobic, anoxic) and groundwater passage (anaerobic) in lab-scale and pilot-plant size sediment columns. Additionally, we aim to employ molecular (16S-rRNA sequencing), biochemical (in-vitro activity assays) and shot-gun proteomics analysis to identify transforming organisms and proteins.
