The method delivers reliable results within a maximum of 48 hours—even in cases where traditional culture-based methods reach their limits.

Probiotics are becoming increasingly important as part of many people’s diets. As demands for quality, product safety, and verification of the microorganisms present continue to rise, so does the need for reliable microbiological testing methods. The BAV Institute is therefore now offering a new, non-culture-based method for determining the total cell count of microorganisms and supports, among others, probiotic manufacturers in conducting rapid and reliable quality control.

Until now, the determination of probiotic microorganisms has often been carried out using traditional culture-based methods. However, these methods reach their limits with many probiotics: The microorganisms present differ significantly in their growth characteristics, and in some cases are difficult or impossible to culture on conventional culture media. As a result, analysis results may underestimate the actual total cell count and distort the assessment of the microorganisms present in the product. In addition, the methods used can be costly.

With this new analytical method, the BAV Institute offers a reliable alternative. Since the method works independently of the microorganisms’ cultivability, it enables a realistic determination of the total cell count. Results are available within a maximum of 48 hours and provide a robust basis for the microbiological quality control of probiotic products.

“With our new method, we can determine the total cell count of probiotic microorganisms much more accurately than with traditional cultivation methods,” explains Dirk Lorenz, a state-certified food chemist and Key Account Manager at the BAV Institute. “Furthermore, our technique, which is based on microscopic methods, is significantly more cost-effective than other alternative methods, such as flow cytometry.”

By expanding its testing portfolio, the BAV Institute is responding to the growing demands of the food and dietary supplement industries. The new method helps companies assess the microbiological quality of their probiotic products and design their quality processes efficiently and cost-effectively.

In addition to probiotics, the method is also suitable for determining the total cell count in fermented products as well as in samples containing a high number of microorganisms that are difficult to culture.
