Webinar: Invisible Danger in Juice

Alicyclobacillus – Detection, Control, and Prevention

 

 

 

Dates and registration

As part of the webinar "Invisible Danger in Juice: Alicyclobacillus – Detection, Control, and Prevention", professionals from the fruit juice and concentrate industry will gain in-depth insights into the biology, detection strategies, and prevention approaches for Alicyclobacillus spp.

The focus is on current research findings and the application of modern gene probe technology in quality control laboratories.
 

Upcoming Dates:July 8, 2025
Time:6:00 PM (CET)
Duration:60 minutes + Q&A session
Speakers:

Dr. Jiri Snaidr
(Founder of vermicon AG and microbiologist,
expert in microbial biocenoses)

Dr. Claudia Beimfohr
(CTO of vermicon AG and expert in microbiological quality control)

Platform:Zoom Webinar
Language:English

Objective of the webinar

Alicyclobacillus spp. are among the most critical spoilage organisms in the fruit juice industry. Their spores, especially Alicyclobacillus acidoterrestris, can survive common pasteurization processes, produce off-flavors (notably guaiacol), and render entire batches economically worthless.

This webinar demonstrates how this invisible threat can be detected in time, microbiologically contained, and prevented in the long term – with specific recommendations for quality management and laboratory practice.

The two core topics of the webinar:

  • TALK 1: Alicyclobacillus Reloaded – Biology & Quality Management (Dr. Jiri Snaidr)
    • Current state of taxonomy and genomic diversity
    • Spore formation and extreme resistance mechanisms
    • Biofilms: from zero to a million-strong colony
    • Guaiacol pathway: the origin of the “disinfectant aroma”
    • Overview of recent studies and their relevance for practice
    • Prevention along the entire production line: from raw material to bottling
       
  • TALK 2: Molecular Guardians – VIT® & Flow VIT® in the Quality Lab (Dr. Claudia Beimfohr)
    • Rapid detection with VIT® gene probe technology
    • Automated monitoring using Flow VIT® and flow cytometry
    • Practical examples: application from raw material to finished product
    • Economic benefits: shorten storage times, avoid recalls
       

 

The webinar is complemented by real-world case studies that illustrate practical implementation. They demonstrate how targeted microbiological control can stabilize production processes, improve cost-efficiency, and create long-term competitive advantages.

Microbial Quality Control

You’ve detected microbial contamination in your sample and want to assess the potential impact on your production? We offer a comprehensive service portfolio and a wide range of test kits for rapid and specific quality assurance across the entire production chain – from raw material to finished product.

VIT® Alicyclobacillus

The detection of Alicyclobacillus acidoterrestris, including both vegetative cells and spores, as well as the entire <i>Alicyclobacillus</i> genus, can be performed quickly and specifically. Evaluation is carried out using fluorescence microscopy.

Flow VIT® Alicyclobacillus

With the rapid test, all members of the Alicyclobacillus genus, including Alicyclobacillus acidoterrestris, are clearly detected and identified. The flow cytometer evaluates the sample automatically, ensuring fast and reliable quality control.
