The Biotechnology Division of the Bay Zoltán Nonprofit Ltd. of Applied Research in Szeged offers state-of-the-art solutions, new knowledge and complex analytical methods for the food industry with years of experience.


What problems can we help you with?

  • In case you require tests related to production technology, quality control: identifying biotechnological or hygiene problems, risk assessment and proposing solutions and treatments.
  • Studies related to new product development: laboratory scale enzymatic and live cell transformations, fermentation experiments using yeasts and lactic acid bacteria with microbiological, molecular biological and analytical monitoring.
  • Preservation of product: preservative efficiency test, challenge test using isolated microorganisms from microbial strain collection or industrial environment; microbial cell tracking during storage with classical microbiological and molecular biological methods; water activity measurement; microbial death modelling; matrix effect calculation; impact assessment of storage conditions to determine the ideal temperature and atmosphere.
  • Determination of germicidal efficiency.
  • Specific requests about isolating, characterising and maintaining strain isolates from a given operational environment.


Why choose us?

  • We work with a complex team of experts (biologists, chemists, and food engineers) supported by our national coverage.
  • We have a state-of-the-art, full-service chemical, microbiological and molecular biology laboratory.


Available infrastructure:

  • strain or function-specific molecular biology measurements (PCR, qPCR)
  • microscopy (light, stereo, fluorescence)
  • spectroscopy (UV-VIS, fluorescence)
  • elemental analysis (ICP-OES),
  • chromatography (GC-MS, HPLC-DAD)
  • aerobic, anaerobic incubators
