University of Natural Resources and Applied Life Sciences, Vienna Centre for Nanobiotechnology Universität für Bodenkultur Wien Zentrum für Nanobiotechnologie NanoGlykobiologie-Gruppe PhD Position for the … Biochemical and Molecular Analysis of the Cell Wall Glyco(prote)ome of Lactobacillus buchneri Short summary of project Lactobacillus buchneri strain CD034 possesses a complex cell wall architecture. The main focus of the work lies particularly on the cha- racterization of the glycosylated cell wall constituents of this organism, such as the two-dimensionally crystallizing S-layer glycoprotein, a puta- tive secondary cell wall polymer (SCWP) involved in S ‑ layer anchoring, and the identification of a predicted exopolysaccharide (EPS) which is known from other lactic acid bacteria. In this context it should be ment- ioned that between S ‑ layer carrying and S ‑ layer deficient bacteria strain-specific differences may exist regarding architecture, composit- ion and function of specific cell wall constituents. The presence of an S-layer glycoprotein on this GRAS organism, which makes it an interesting candidate for possible future glycan-related medical and/or biotechnological applications. Requirements The candidate must hold a MSc degree and should have a sound background in molecular biology, micro- biology, biochemistry. Practical experience in the field of glycobiology is of advantage but not mandatory. The highly motivated candidate should be an excellent team player with the ability to work independently in an interdisciplinary environment. Research goals  Bioinformatic analysis of the genome of L. buchneri CD034 for loci harboring genes involved in the biosynthesis of glycosylated cell wall components of L. buchneri CD034 (in collaboration with Prof. R. Grabherr, IAM, BOKU).
