Optimisation of Bacillus subtilis for the secretion of heterologous proteins Therapeutic proteins (including those required for experimental purposes and clinical trials) are major products of biomanufacturing processes and considerable time and expense are expended to maximise the yield and quality of proteins produced in heterologous hosts. The production host of choice is the Gram-negative bacterium Escherichia coli for which many strains and expression systems have been developed. However, ...

The main component of research in my group is in the determination of macromolecular structures by X-ray crystallography. However, since not all proteins crystallize, every effort is made to complete our understanding of how proteins function by utilizing other methods, such as microbial genetics, monitoring protein:ligand interactions by biochemical and biophysical methods, electron microscopy and bioinformatics

I am pursuing my PhD at Prof. Volker's Lab in the Department of Functional Genomics, EMA Universitat Greifswald, Germany. I am working on the general stress responses mediated by SigB and the prediction of SigB regulon members using the Random forest algorithm.

I am PhD student at Prof.Uwe Voelker lab in Department of Functional Genomics. My area of research is microbial functional genomics in particular analysing the whole transcriptome(by microarray and other molecular biolology methods) of B.subtilis under various stress conditions. I use QconCAT strategy for absolute quantification of carbon metabolic enzymes via MRM(multiple reaction monitoring) by LC-MS/MS. I also perofrm experiments for understanding of dynamics of SigmaB network for modelling.

I started to work with B. subtilis during my diploma thesis in Marburg, analyzing the gene expression pattern during sporulation and their control by the four sporulation sigma factors. This work was continued during my PhD thesis in Greifswald. In collaboration with Prof. Bremer and Prof. Marahiel in Marburg we also studied additional adaptation processes of B. subtilis, like the adaptation to low temperatur and high osmolarity. I am now working as a staff scientist in Prof. Völkers lab in ...

The main area of my expertise concerns protein sorting and secretion in Gram-positive bacteria, such as Bacillus subtilis and Staphylococcus aureus.

The Gram-positive bacterium B. subtilis is well known for its high capacity to secrete proteins into the extracellular milieu, which has led to its exploitation as a "cell factory" for secreted proteins. Nevertheless, the secretion of heterologous proteins of pharmaceutical importance is frequently inefficient. This applied problem has been a major ...

By training I am a molecular microbiologist with a particular interest in bacterial stress adaptation reactions. Since the early 90ies we have used functional genomics technologies, particularly proteomics, to investigate the response of Bacillus subtilis to environmental challenges. I am currently Head of the Functional Genomics Department of the Interfaculty Institute of Genetics and Functional Genomics at the Ernst-Moritz-Arndt-University Greifswald. Within the Department we are applying ...
