Summary
Potato mash, potato mash/maltrin mixtures, maltrin and wheat starch have been fermented with 95 to 98% conversion efficiencies. Highest ethanol yields obtained were 13.5% (v/v) in 24 h. The addition of 20% backset (= thin stillage) or change of pre-culture conditions did not affect the process.
Résumé
On fermente la purée de pommes de terre seule et en mélange avec la maltrine ainsi que l'amidon de froment jusqu'à 95 à 98% d'efficacité de conversion. Les rendements les plus élevés en éthanol sont de 13.5% (v/v) en 24 h. Le recyclage de 20% de résidu fluide de fermentation ou le changement des conditions de préculture n'affectent pas le processus.
