摘要 |
This invention relates to a novel fermentation process and in particular, to fermentative production of ethanol producing in the presence of non-gelled, or granular, starch particles, alpha-amylase and a glucoamylase; characteristic of the present process is recycle of enzymes for renewed use in fermentation, usually through termination of the fermentation prior to complete disappearance of the granular starch particles, and recovery for use anew of the unconsumed starch, along with enzymes thereon. Fermentation according to practice of this invention proceeds at a near to linear rate in the main.
