Doctoral student/ PhD student (m/f/d)
in the Research Project: Reduction of Listeria monocytogenes in meat products by combination of bacteriophages and high pressure.

 

Contamination of cooked and raw fermented meat products with the bacterial food pathogen Listeria monocytogenes continues to lead to product recalls and poses the risk of life-threatening infections. The combination of lytic bacteriophages and mild high pressure to inactivate the pathogen is intended to further reduce the risk of L. monocytogenes occurrence. In the project, a window for the high-pressure treatment will be determined that, together with bacteriophage treatment, allows significant inactivation of the Listeria without significantly affecting the sensory quality of the meat products. Considering the treatment sequence, possible synergistic effects will also be investigated.

 

We offer:

  • Possibility of preparing a doctorate
  • well-equipped microbiological laboratories and technical hall with high-pressure plant
  • A motivated and friendly team in an interdisciplinary environment

 

 

Areas of responsibility
  • Planning, preparation and execution of experiments, data evaluation, and statistical analysis.
  • In vitro studies on the inactivation of L. monocytogenes by high pressure
  • In vitro studies on the inactivation of L. monocytogenes by bacteriophages
  • Challenge tests with L. monocytogenes in meat products to determine the inactivation of Listeria by high pressure, bacteriophages, and the combined application
  • Genome and transcriptome analyses to identify molecular mechanisms of resistance of L.monocytogenes to high pressure and/or bacteriophages
Your profile
  • You have a degree (M. Sc.) in microbiology, biotechnology, food science, food technology or a comparable degree.
  • You have good knowledge in (food) microbiology and practical experience in handling microorganisms. Initial experience in a biosafety level 2 laboratory or in handling risk group 2 microorganisms is beneficial.
  • You are characterized by a reliable and self-responsible way of working.
