Ioannis Kampouris
ESR3: Effect of wastewater irrigation on the passage of ARB&ARG towards ground/surface waters
Supervisor: Prof. Thomas Berendonk
Host Institution: Technische Universität Dresden
Related Working Packages: WP1 , WP5
About me: Ioannis Kampouris received in 2012 a B.Sc. in Biochemistry and Biotechnology from the University of Thessaly, Greece and in 2016 an M.Sc. in Applied Genetics and Biotechnology from Aristotle University of Thessaloniki, Greece. During the bachelor’s thesis he analyzed polymorphisms in mitochondrial tRNA genes between normal individuals and patients with Alzheimer disease. During the master’s thesis he was involved in a multi-disciplinary team project which consisted of chemical engineers, food technologists and biotechnologists. The primary goal of the project was the reduction of biofouling in membrane bioreactors. He conducted his master’s thesis under the supervision of Prof. Petros Samaras and Prof. Minas Yiangou. The main theme of his master’s thesis work included the isolation of a novel strain, from urban wastewater sludge, with high degrading ability of N-acyl-homoserine lactones and the utilization of the isolated strain for the reduction of biofouling in a pilot-scale membrane bioreactor. Now, he is a Ph.D. student at the Technische Universität Dresden, and an Early-Stage Researcher at the ANSWER project. His work focuses on the effect of wastewater irrigation on the passage of ARB&ARG towards ground/surface waters.
Main scientific achievements and experience gained through the ANSWER project: Ioannis Kampouris (ESR3) work in ANSWER-ITN was related with the downstream environments of wastewater reuse. Specifically, he investigated the impact of wastewater irrigation on the profile of ARGs in soil, subsoil pore-water and groundwater. He had several scientific achievements through his project. In the beginning he started with a time-series sampling campaign in the topsoil of a wastewater irrigated field. He sampled during low and high intensity of irrigation in several seasons of irrigation. The sampling took more than one year and it allowed us to elucidate the dynamics of ARGs in the topsoil during irrigation. Out of a small subset of genes, he identified genes that are affected by irrigation and a few genes that probably are part of the native soil resistome (at least in the specific sampled area in Germany). ESR3 also observed of a plateau effect where the increase of relative abundance of ARGs stops at certain point of continuous irrigation. Another big part of his work has focused in the effect of wastewater irrigation in other downstream environments: subsoil pore-water and groundwater. While the results showed that the same genes increased from wastewater irrigation in the topsoil increased in subsoil pore-water and groundwater. However, there were peculiar dynamics of DNA yield in the subsoil pore-water and groundwater. The campaigns lasted around two years and they showed that when intensive irrigation occurs the absolute abundance of genes and DNA yield in the groundwater usually decreases. Therefore, soil rather wastewater seems to be the bigger contributor of microbial abundance in the groundwater. In contrast, the relative abundance of a few resistance genes to 16S rRNA, which is an indicator of abundance of total microbial community, increased. In addition, in the last part of his work he coupled the campaigns with mesocosms experiments to verify the campaigns’ results. He gained experience in several topics through ANSWER-ITN, mostly scientific ones. First of all, his language skills improved these three-years, since he is speaking daily English, which rarely happened to him in his native country. Second (and most important), he learned several novel biological methods and he improved my organisation skills. Apart from qPCR, he learned also several bioinformatics pipelines and to work with the programming language R. These 3 years he became more expert in the wastewater and soil/groundwater microbial ecology. In addition, ESR3 encountered several other young researchers from other European regions through the training events. They also originated from similar or completely different scientific fields and they had their own view on the subjects, which was very interesting. He really enjoyed the presentations, interactions and discussions and they were always meaningful to him, while in parallel led to change of his way of thinking and fruition of new ideas.

His research focuses on the uptake of antibiotics and antibacterial contaminants in crops.
Main scientific achievements and experience gained through the ANSWER project: The very first achieved objective of Đorđe Tadić (ESR8) was to develop and validate a quantitative, sensitive, reliable, and practical methodology for the simultaneous determination of 10 antibiotics belonging to four chemical classes (i.e. fluoroquinolones, sulfonamides, lincosamides, and metoxybenzylpyrimidines) and 6 of their metabolites in four different vegetables matrices (lettuce, tomato, cauliflower, and broad beans). During 2016 and 2017 several sampling campaigns were performed, during summer and winter farming periods. Four aforementioned types of vegetables and soil samples were harvested from the farms located in the peri-urban area of Barcelona, Spain. The samples were screened for the presence of antibiotics and their metabolites applying developed analytical method (target screening). Additionally, vegetable samples were screened for 2098 suspected emerging substances, that can be found in Suspect list “S1 MASSBANK”, using “NORMAN digital sample freezing platform”. In order to identify antibiotic metabolites, HR-MS MSn methodologies was applied. Consequently, the data obtained using last generation Orbitrap instrument – Fusion provided enough information for tentative identification of several metabolites for three antibiotics (i.e. trimethoprim, ofloxacin, and sulfamethoxazole) detected in lettuce seedlings grown in controlled conditions. The structure elucidation of metabolites based on direct substructure identification was a major accomplishment, and a substantial improvement over the traditional indirect structure identification methods of compounds not present in spectral libraries.

Main scientific achievements through my project: The fate and transformation of selected antibiotics (i.e. azithromycin, ofloxacin, sulfamethoxazole and trimethoprim) during UV-C and UV-C/H2O2 oxidation in ultrapure and secondary-treated wastewater effluents, as well as, the identification of their transformation products (TPs) by applying suspect and non-target strategies based on liquid chromatography quadrupole-time-of-flight mass spectrometry (LC-QTOF-MS) was investigated. The complementary use of Reverse Phase Liquid Chromatography (RPLC) and Hydrophilic Interaction Liquid Chromatography (HILIC) for the identification of polar TPs was also examined. Moreover, four of the effect-based reporter-gene CALUX® bioassays were applied to assess multiple toxicological endpoints, i.e. the potential genotoxicity, oxidative stress and cytotoxicity of the UV-C and UV-C/H2O2 treated samples. More specifically, the tested bioassays were p53, p53 (+hepatic S9 as exogenous metabolic system), Nrf2 and Cytotox CALUX®. The most relevant commercially available TPs were purchased in order to assess their biological potency through the application of the beforementioned bioassays as well as their antimicrobial activity. For the first time reported, the Minimum Inhibitory Concentration (MIC) i.e. the lowest concentration of the target antibiotics and their commercially available TPs that inhibit the growth of selected strains of environmentally- and clinically-relevant bacteria was determined.
Main experience gained through my project: The intersectoral and multinational mobility throughout the project has increased Vasilikis Beretsou (ESR14) flexibility and adaptability in different working environments (both in research and industrial environments). Through networking and collaboration, ESR14 has expanded her knowledge in other scientific fields. ANSWER has promoted not only her research skills but also her complementary and transferable skills such as the preparation of research proposals, her project management skills and the development of strong written and oral communication skills. She believes that the MSCA fellowship can be considered a valuable asset both in the case you want to pursue a position within or outside academia. All these would have never been possible via a more traditional PhD pathway!

About me: Nikiforos Alygizakis holds a B.Sc. in Chemistry and a M.Sc. in Chemical Analysis and Quality Control awarded by the University of Athens. His B.Sc. was funded by Athens University Legacy Foundation (Antonios Papadakis Legacy) and his M.Sc. by John S. Latsis Foundation. During his studies, he developed both analytical and programming skills. He is experienced in many sample preparation and instrumental techniques as well as programming, mainly using R language. He was trained on testing the quality of medicines during his four-month internship at the National Organization for Medicines of Greece. Moreover, he joined Prof. Thomaidis’ research team at the University of Athens, where he worked on sewage epidemiology field. He participated in many collaborative trials (COST action ES1307) and employed LC-QqQ to determine drugs of abuse and pharmaceuticals including many of their transformation products in different matrices. During his master thesis, he conducted research using state-of-the-art analytical equipment (LC-QTOF) and cutting-edge data processing tools to detect compounds with high fluctuation among replicated time-series wastewater samples and identify them using non-target strategies. His research interests are focused on treatment of LC-HRMS data, prioritization methodologies and non-target screening. Currently he is a Ph.D. Candidate to University of Athens and a Marie Curie Early-Stage Researcher at the ANSWER Project, and his work is based on the development of advanced methods for the identification and risk assessment of antibiotics and their transformation products in wastewater.
