Is Cell Counting A Good Method For Monitoring Your
Fermentors?
• It has been used for decades, but ………..
• Cell counting is:
– Time consuming
• 10-12 minutes per sample
– Subjective and highly variable/person
• Lots of opportunity for error and “pencil testing”
• Cell counting samples just a small population
– 100’s of yeast cells tested
• YAM evaluates a much larger population
– 1,000,000’s of yeast cells

4. The Nalco Yeast Activity Monitor
Why Use It?
• Provides a direct measure of yeast activity:
– During propagation & fermentation
• The YAM measures only viable (vs live/dead) cells
• The YAM also measures cell vitality
– Metabolic rate (Old person vs young person)
• The YAM data correlates accurately to real ethanol
production
• The YAM is capable of running up to four samples
at the same time in one piece of equipment
– Vs one cell count per microscope

5. The Nalco Yeast Activity Monitor
Why Use It?
• The YAM generates precise
and accurate data
• All data is:
– Logged
– Readable on any computer
– Can be shared via e-mail
– Can communicate with the
DCS
• The YAM is great for
determining optimum drop time
in yeast propagation process
– Better timing means increased
productivity
