Project overview

The aim of this project is to enhance the exopolysaccharide (xanthan) production of Xanthomonas campestris pv. campestris by obtaining a deeper understanding of the Xcc central metabolism, which is the source for the precursors essential for xanthan biosynthesis. Therefore, relevant metabolic pathways should be reconstructed and analysed by means of systems biology. The results of these analyses should be validated by analysing the metabolic flux and the effect of mutations affecting relevant pathways.
