Yeast Activity
Monitor™

GenPrime’s Yeast Activity Monitor™ is faster, more accurate and less labor intensive than traditional yeast management methods. Plus, the device offers cutting-edge software that measures yeast vitality.

Cutting-Edge Science
The monitor works by introducing a dye molecule into a yeast sample. Healthy cells metabolize the dye, producing a fluorescent signal. The handheld reader measures this signal and assigns digital values that can then be used to track yeast activity throughout the propagation and fermentation processes.

Rugged and Easy to Operate
The Yeast Activity Monitor’s compact and rugged design makes it a perfect fit for the lab or any industrial setting, plus it requires very little skill to operate. Training can be completed in less than an hour. Furthermore, each test can be completed in less than 10 minutes, which can ultimately reduce labor costs.

Brewing Applications
More effective yeast management also greatly improves quality control for brewers. Accurate fermentation information prevents off-flavors in the product and reduces the need for blending. GenPrime’s Yeast Activity Monitor™ quickly determines inoculation rates, so operators can maintain consistent fermentation and batch-to-batch consistency.

Fuel Ethanol Applications
GenPrime’s Yeast Activity Monitor™ offers the best way to maximize production output and efficiency in fuel ethanol production plants. Healthy yeast produces up to 33 times more ethanol than stressed cells. Because our test device quickly and accurately measures yeast activity and vitality during the fermentation process, technicians can easily adjust factors to obtain peak performance.

The History of the Yeast Activity Monitor™
“In 1997, soon after GenPrime was formed, we were approached by a large supplier of yeast starters to brewers. They asked if there was a way that we could measure the activity of the yeast that developed during the beer brewing process. We created some novel chemistry (i.e. buffers and metabolic dyes) that turned out to give a good indication of yeast activity via reactive color change (and quite understandably, we called the system the Yeast Activity MonitorTM, or YAM for short). We soon also determined that the YAM had additional fermentation applications including cheesemaking and fuel ethanol production. The development of the YAM represented the first commercial success for GenPrime, and established our company as an innovative leader in the microbiology and biotechnology sectors. With our pivot in the early-2000’s toward medical devices, the YAM eventually became a smaller component of our overall business, where it continues to be routinely used for authentication and quality management purposes.” - Buck Somes, CEO
