COMBINED USE OF AT LEAST ONE ENDO-PROTEASE AND AT LEAST ONE EXO-PROTEASE IN AN SSF PROCESS FOR IMPROVING ETHANOL YIELD

COMBINED USE OF AT LEAST ONE ENDO-PROTEASE AND AT LEAST ONE EXO-PROTEASE IN AN SSF PROCESS FOR IMPROVING ETHANOL YIELD

Improved processes for producing ethanol from starch-containing materials by the combined use of at least one endo-protease and at least one exo-protease in an SSF process are disclosed. More particularly the exo-protease should make up at least 5% (w/w) of the protease mixture. L'invention con...

Beschreibung
Zusammenfassung:Improved processes for producing ethanol from starch-containing materials by the combined use of at least one endo-protease and at least one exo-protease in an SSF process are disclosed. More particularly the exo-protease should make up at least 5% (w/w) of the protease mixture. L'invention concerne des procédés améliorés de production d'éthanol à partir de matières contenant de l'amidon par l'utilisation combinée d'au moins une endoprotéase et d'au moins une exoprotéase dans un procédé de fermentation en milieu solide. Plus particulièrement, l'exoprotéase doit constituer au moins 5 % (poids/poids) du mélange de protéases.
