Bakers Yeast Production
Process.
The technology to produce bakers yeast (Saccharomyces cerevisiae) has been
successfully developed in the pilot plant at PDTI with a capacity of 1 ton dry weight
bakers yeast per month. Sugar feed in fed-batch fermentation is precisely controlled
based on the respiratory quotient, using PID (Proportional & Integral &
Derivative) control. Final volumetric yields are 80 grams dry weight per liter,
representing a growth yield coefficient of 0.33 gram dry yeast per gram sugar.
