The analysis of yeast, its quantity (concentration) and viability used for brewing is one of the most important factors in determining the quality and taste of a product.

 

Determination of the total number of yeast cells in beer

The concentration and viability (percentage of living cells) of yeast cells are important factors in various fermentation and production processes. Brewing requires special care, as it is necessary to achieve the same flavor every time. To ensure consistency, one of the critical factors is the number of live and dead yeast cells used when pitching.

ChemoMetec's NucleoCounter automatic cell counters measure cell counts and viability with the precision and reliability required by brewers. The devices allow the user to quickly, objectively and accurately measure the amount and viability of yeast. Unique disposable cassette sampling devices provide ease of use and eliminate the need for manual analysis and contact with reagents, ensuring very high accuracy.

Application of NucleoCounter NC-202 and YC-100 analyzers in brewing

NucleoCounter Cell Analyzers can analyze volumes more than three times the volume normally analyzed by manual cell counting. As a result, this feature makes them one of the leading automated cell counters on the market for accuracy. NucleoCounter can provide fast and accurate DNA-based cell counts within seconds, regardless of foreign matter or substrate aggregates in the environment.

The system uses disposable sampling devices that are preloaded with fluorescent dyes to detect and quantify total and viable cell populations. Because the NucleoCounter Cell Analyzer detects signals from stained nuclei and does not rely on imaging the entire cell, the system works regardless of cell size and morphology.

NucleoCounter YC-100 - a laboratory yeast cell analyzer designed for the brewing industry. It is used to count cells in pitching yeast, yeast in suspension, and dry yeast.

This automatic cell counter is equipped with a camera and built-in fluorescence microscope designed to detect signals from a fluorescent dye, propidium iodide (PI) bound to DNA. Results represent total or non-viable cell concentration, depending on sample preparation. Disposable NucleoCassetteare used for sampling.

The NucleoCounter NC-202 collects additional parameters and is suitable for more complex samples or when detailed studies are required. In addition, the NC-202 comes with GMP compliant software for superior data management. The NC-202 analyzer uses disposable Via2-Cassette cassettes for sampling.

More and more industries in the beverage and food industry, in addition to beer, produce beverages in which it is also necessary to control the content of yeast in order to maintain the taste properties, including: kombucha, kefir, kvass, root beer, food additives such as probiotics, yeast extract and vitamins.

Non-consumer products include bioethanol for energy production and for the bioremediation of toxic or non-toxic waste and by-products from many industries.

Using NucleoCounter in production runs

The Saccharomyces cerevisiae endomembrane system (brewer's yeast) makes it a cost-effective alternative for protein production requiring post-translational modifications. Many biomedical manufacturing plants use genetically modified yeast as biofactories to produce proteins, including insulin and other hormones, vaccine antigens, and blood factors.

The NucleoCounter NC-202 is the most accurate and consistent yeast cell counter for continuous monitoring of success criteria in production runs. The unique Via2-Cassette ensures safe and easy sample handling and eliminates operator error for both experienced and new users.
