Probiotics: New microbiological
methods for exceptional quality

Direct, modern microbiology with VIT®: The industrial standard for
Fluorescence in Situ Hybridization (FISH). Identity, purity, stability and
viability analysis directly in the sample.




Why do we need new microbiological methods?

The development and manufacturing of probiotics requires profound microbiological understanding of the relationship and interactions between the selected microorganisms as well as with the host microbiome ecosystem. However, there are certain obstacles and limitations of conventional and novel microbiological methods, like next generation sequencing (NGS) and flow cytometry, that researchers have to overcome in order to gain the required knowledge.


Why VIT® and vermicon?

VIT® is a molecular technique which uses specifically programmed fluorescent labelled probes (single strand of DNA that is complementary to a microbial rRNA region of interest). The analysis is performed via fluorescence microscopy or flow cytometry (Flow VIT®). VIT® and Flow VIT® can specifically identify multiple bacteria populations in the same sample, distinguish between live, damaged and dead cells and are cultivation independent. Our mission is to dissolve the methodological limitations and enable the development and production of exceptional probiotics. Using VIT® makes that possible.

Microbiome research

Microbiome research

The human microbiome is a highly complex ecosystem. Products based on living microorganisms generally don’t work in a direct way, but interact in a multifactorial mode of action.

Live Biotherapeutics

Live Biotherapeutics

To ensure the efficacy and safety of Live Biotherapeutics, a deeper understanding of the relationship between the microbiome and the human health is needed.

Expertise and technology
