ISO 19344 Quantification of Probiotic Bacteria by Flow Cytometry
The quantification of probiotic bacteria is a critical step in ensuring the safety and efficacy of dietary supplements, fermented foods, and other products that contain live microorganisms. ISO 19344 provides a standardized method for quantifying probiotics using flow cytometry, which enables high-throughput analysis with precision and accuracy.
The process involves several key steps: first, the probiotic sample is prepared in a buffer solution to ensure optimal viability and stability of the bacteria. Then, the prepared sample is stained with a fluorescent dye specific for bacterial cell walls or nucleic acids before being analyzed via flow cytometry. The machine counts individual cells as they pass through a laser beam, measuring their fluorescence intensity.
The accuracy of this method lies in its ability to differentiate between live and dead cells based on the presence of intact cell membranes, which is crucial for ensuring that only viable probiotics are counted. This approach ensures compliance with regulatory requirements set out by various international standards such as ISO 19344.
Flow cytometry also allows for additional analyses beyond simple quantification. For instance, it can assess the viability of the probiotic bacteria over time or compare different strains within a single species. These supplementary tests provide valuable insights into product quality and shelf life stability during storage.
A notable advantage is that this technique offers faster results compared to traditional culture-based methods like plate counts which require days to complete an analysis. In contrast, flow cytometry can deliver quick turnaround times suitable for rapid development cycles in R&D environments or frequent quality checks needed by manufacturers.
For instance, a recent case study conducted at a leading probiotic manufacturer showed that implementing ISO 19344 led to improved consistency across batches and reduced variability in final product content. By adhering strictly to the outlined procedures specified in ISO 19344, they were able to meet stringent quality control standards more efficiently.
In summary, employing flow cytometry according to ISO 19344 represents an essential tool for laboratories aiming to ensure accurate quantification of probiotic bacteria. It supports compliance with regulatory expectations while providing actionable data that enhances both product safety and efficacy.
