In today’s ethanol market, producers need an edge to maintain profitable operation.  Mascoma has developed a unique advanced bioengineered yeast product expressing starch-degrading enzymes that can also reduce glycerol produced in fermentation. The bioengineered yeast is used to reduce the amount of commercial enzymes purchased in the ethanol industry and also results in a higher ethanol yield compared to conventional yeast. In this presentation, experimental data generated from Design of Experiments (DOE) for the selection of candidate strains using full factorial design will be discussed. The selection criteria that were used as well as pilot and commercial results will be discussed.
