Our research in a nutshell
Research topics The working group is studying the degradation and effects of antibiotics in the environment , especially in agricultural soils. The focus is on both the antibiotics themselves and the resistance genes in the bacteria. The specificity of the latter stems from their potential to replicate and spread in the environment and, when transferred to pathogens, to threaten human and animal health . Therefore, for the development of strategies to contain antimicrobial resistance, it is necessary to consider human, animal, and environmental health together (OneHealth approach). The environment in particular has been insufficiently addressed in previous measures. Investigate the fate and degradation of antibiotics in soil-plant systems and identify bacterial degraders. understand the effects of antibiotics on bacterial community activity in soil-plant systems. identify the drivers for the persistence and transfer of antibiotic resistance in bacterial communities in soils. assess the potential threat starting from antibiotic resistance in soils to human and animal health. find out the removal possibilities of antibiotics and antibiotic resistances from wastewater/slurry.

News We warmly welcome our new postdoctoral researcher Mary Eliza to the group! She holds a PhD in Soil Evolutionary Microbiology from the University of Sheffield, where she focused on harnessing soil microbiomes for sustainable agriculture. She will be working in the ANTIRESIST project.
We are happy to welcome our new postdoctoral researcher Debjyoti Ghosh! In his PhD he worked on soil metaproteomics in the context of agricultural management. He is now bringing his expertise to several ongoing projects, focusing on the functional characterization of bacterial communities in soil-plant systems.
We are happy to announce that we are looking for a new student to work with Lieke in the SmartManure college. If you are interested in doing an internship, bachelor or master thesis on this topic, have a look here .
We had our group Christmas party involving a lot of quizzes and nice food! We wish everyone merry Christmas and a happy New Year!
We welcome Dr. Luis Daniel Prada Salcedo as a new postdoctoral researcher to our group! He is involved in the pilot project ResistChange and investigates the impact of climate change on the spread of antibiotic resistance from livestock manure to soils under various agricultural management practices.
Maja, Chika and Franzi participated in a workshop for our new digital PCR from QIAGEN.
Haining and Chika presented posters at the 3rd IP Day of the Integration Platform 4 'Tapping nature's potential for sustainable production and a healthy environment'.
Welcome to Franziska Raab, a new PhD student in our group! As a part of the project ANTIRESIST, she will work on the effects of antibiotics on the bacterial activity in soil-plant systems.
Welcome Jiaojiao Xu to the group! She is an exchange PhD student from South China Agricultural University working on conjugative transfer of ARGs among bacterial communities of swine manure.

Welcome to the group Lieke! Lieke Lipsch is part of the SmartManure PhD college and will spend the next three years investigating whether cover crops can mitigate the negative environmental impacts of manure application on agricultural soils.
We are very happy to welcome Haining Huang as a new PhD student in the group! Haining will be working on extracellular vesicles in soils and their role in the spread of antibiotic resistance in the soil microbiome.
Wenxuan Chen joined the group as a visiting PhD student. She will be working on the development of QSAR models for the prediction of antibiotic rejection by membranes. Nice to have you on board!
Dr. Chika Ejikeugwu joined our group via a Humboldt Fellowship for experienced researchers. Chika will work on the effects of antibiotic mixtures in soils. Welcome!
After one year with us, we say goodbye to Xin Wen, who is going back to South China Agricultural University after her stay as a guest PhD in our group. Thank you Xin for the good time and good luck on your further way! We also look forward to continuing our collaboration in the future.
Hendrik Seifert will now continue the work he did during his internship in the FULLREMOVAL project as a master student under the supervision of Fátima. Welcome back Hendrik!

We warmly welcome Fátima as a new postdoc to the group. Fátima will be working on her MSCA-funded project FULLREMOVAL for the next two years.
Kristina Scholz is joining the working group as an intern for the next three months. Welcome Kristina!
Hanna's bachelor thesis will investigate the mechanisms of antibiotic resistance persistence in soils.
Since February, Maja Hinkel is supporting the working group as a technical assistant. She will develop and apply protocols to determine hosts of antibiotic resistance genes in soil. Welcome Maja!
Johanna Zech will do an internship with us until the end of February. She will investigate how soil biophysical conditions affect the invasion success of antibiotic-resistant bacteria.
Our BELL student Johanna Rasch participated very successfully in the regional Jugend forscht contest. She took the first place in the biology category and also received the Carl-Friedrich-Gauß-Award.
Congratulations Johanna!
The MDR series "Mission: Saving the world" featured our work on antibiotics in soils.
