Testing Date: 2/25/2013
Total viable cell density: 50 million cells per ml
Thick Viable Cell Density: 1.2 billion cells per ml
Stress level: Low, Similar characteristic flavors to previous batch.
Bacteria level: Very Low, Sourness unlikely. (no bacteria visible)
Viability – Percentage of live cells of the entire cell population
Total Viable Cell Density – The number of viable cells in one milliliter of homogenized slurry.
Thick Viable Cell Density – The number of viable cells in one milliliter of settled cells such as those at the bottom of a starter that has been refrigerated.
Stress Level – A rudimentary assessment of cell health based on cellular morphology.
Bacteria – The percentage of visible bacteria of the yeast population
