Modeling of rhizosphere influences on interactions between chemical dynamics and effects of veterinary medicines in soil (Project)
The simulation models developed in the 1st phase integrate the chemical fate of the veterinary medicines sulfadiazine (SDZ) and difloxacin (DIF) in bulk soil and their subsequent effects on soil microorganisms and on soil functions after single-dose application with manure. In the 2nd project phase, this approach is extended to the rhizosphere, which represents the hotspot of microbial growth in...

Fate, metabolism and plant uptake of selected veterinary medicines in the rhizophere (Project)
The ultimate goal of our project is to generate data on the fate and behavior of two antibiotics and their metabolites in the rhizosphere of plants after application of manure onto soil. In a micro ecosystem we will monitor the fate and metabolism of the drugs by collecting pore water from the rhizosphere at high spatial and temporal resolution by using micro suction cups. In addition we want to...

Effects of Veterinary Medicines on the functional diversity of the microbial biomass in soils (Project)
Antibiotics enter the environment by dispersion of sludge and manure used as fertilizer in agriculture. Due to their effectiveness against bacteria important soil functions could be affected and processes in element cycles might be disturbed. Studying the antibiotic sulfadiazine changes in the gene expressions of several N-cycling genes as well as effects on different N-transformation processes...

Effects of veterinary medicined in manur on the abundance and transfer of bacterial antibiotic resistance genes in soil: importance of the rhizosphere and of repeated manure applications (Project)
In the first phase of this project we showed that soil fertilization with manure containing antibiotics enhanced the abundance of antibiotic resistance genes and their transferability, and identified a plasmid type that plays a major role in horizontal spread of resistance genes between manure and soil bacteria. In the second phase we aim to elucidate if the effects of soil fertilization with...

Degradation and Residue Dynamics of Veterinary Medicines in Soil-Plant Systems (Project)
Aim of the project is to characterize the fate of veterinary pharmaceuticals (sulfadiazine, SDZ, and difloxacin, DIF) in manure amended soil in presence of maize, i.e., the kinetics and mass balance of degradation, mineralization rates, the formation of non extractable residues (NER) by parent compounds and metabolites, the potential remobilization of NER as well as the structural elucidation of...

Transport of veterinary medicines from soils to groundwater (Project)
Studies on the mobility and leaching of veterinary medicines are continued using soil columns and lysimeters. The lysimeters that were manured with slurry from pigs medicated with either 14C labelled sulfadiazine (SDZ) or 14C labelled difloxacin (DIF) will be sampled destructively in order to obtain mass balances on the fate of the veterinary medicines and their metabolites. Soil from the...
