PhageCheckTM is a rapid phage test that identifies susceptibilities of bacterial culture to infectious bacteriophages in whey, milk, starter culture and in the environment.


Dairy fermentation relies on indirect and time consuming measurements, such as monitoring acidity of the fermenting milk during the fermentation process or counting of plaques on agar plates.

In contrast, PhageCheckTM is simple and it can:

  • Identify susceptible cultures early in the process by detecting low phage count
  • Improve workflow for phage testing and clean up
  • Manage phage build up in the facility


PhageCheckTM is a simple and fast phage test with no sample preparation required.

The candidate is expected to have experience in more than one of the following areas:

  • Culturing and isolating bacteria or bacteriophages from growth media.
  • Characterization of bacteria and bacteriophages by plate counting.
  • Characterization of bacteria and bacteriophages by fluorescence plate reader.
  • Isolation and characterization of DNA/RNA from both bacteria and bacteriophages.
  • Developing experimental protocols.
  • Writing reports and operating procedures.


Minimum of a BS degree with some lab experience.

The appointment is typically for 3-6 months. Candidates can provide contact information and a very brief CV in the Comments box.
