Laboratory Analysis: Screening of All Beer Spoiling Bacteria
Comprehensive screening for beer spoiling bacteria is carried out in beer and beer-based mixed drinks, environmental and process samples. The following bacteria are searched for in the sample and specifically identified if present: Lactobacillus backi, Lactobacillus brevis, Lactobacillus buchneri, Lactobacillus casei, Lactobacillus paracasei, Lactobacillus collinoides, Lactobacillus coryniformis, Lactobacillus frigidus, Lactobacillus fructivorans, Lactobacillus lindneri, Lactobacillus perolens, Lactobacillus plantarum, Lactobacillus pseudoplantarum, Lactobacillus rossiae, Megasphaera cerevisiae, Pectinatus spp., Pediococcus damnosus, Pediococcus inopinatus.
You will receive the results on the 3rd working day after receipt of the sample. In the case of finished enrichments, at the latest on the 1st working day after receipt of the sample.
Qualitative or quantitative detection?
Qualitative
How is the analysis carried out?
By using the reliable VIT® gene probe technology.
What are the requirements for the sample to be sent in?
Product or raw material samples of:
- Beer and beer-based mixed drinks, min. 100 ml
Pre-enriched samples:
- Enrichment broth (10 ml) or agar plate with colonies: This leads to an acceleration of the detection.
We recommend our kits for analyzing beer samples directly on site:
VIT® Beer Megasphaera/Pectinatus
Your Advantages
VIT® technology enables the targeted detection of individual microorganisms at population, genus or species level. The use of highly specific, rRNA-based gene probes ensures clear identification of the target organism directly in the sample.
The VIT® gene probes hybridize only with intact, metabolically active cells, as only these have sufficient amounts of ribosomal RNA. This means that only living beer spoiling bacteria are detected, while dead or inactive cells are excluded.
Complete detection is completed in just 3-5 hours - a decisive advantage over cultivation-based methods, which take several days due to enrichment, incubation and evaluation. The VIT® technology therefore enables significantly faster decisions in quality assurance, process control and release.
The VIT® technology is based on over 25 years of experience in the development of specific, fluorescence-labeled gene probes for microbiological analysis. It is characterized by high specificity, reproducibility and resistance to interfering matrices.
A particular advantage: as the method is based directly on rRNA and does not require enzymatic amplification steps, it is insensitive to inhibitors. False-positive results, which can occur with PCR-based test kits - especially in complex matrices - are therefore ruled out.
