Studies on the behaviour of endocrine disrupting compounds in a membrane bioreactor
The present research focuses on the fate of hydrophobic micropollutants in a membrane bioreactor (MBR) and their removal in it. MBR represents one of the most promising innovations in the field of wastewater treatment because of the high efficiency in removal of organics and nutrients. The high …

Metabolism of nonylphenol by human P450-recombinant yeast and assessment of the xeno-hormone potency of different isomers and their chlorinated derivates
The purpose of this study was to obtain a better understanding of the behaviour, the characteristics, the metabolism and the metabolites or derivatives of 4-nonylphenol isomers (4NP) regarding the risk of exposure for human health to these compounds. The development of efficient molecular tools, …

Optimierung der Bisphenol A-Biosorption von Saccharomyces cerevisiae auf Basis eines oberflächen-exprimierten Rezeptorproteins
The elimination of endocrine disruptors, like bisphenol A, from wastewater is an environmental challenge of increasing importance, but no satisfying technical solution has been achieved until now. Thus, it was the aim of the present dissertation to increase the bisphenol A-affinity of yeast by cell …
