Abstract
Glucose or other substrate is converted to ethanol using immobilized bacterial cells under conditions which prevent growth of the cells.
Claims16
A process for producing ethanol, wherein a carbohydrate is converted by immobilized cells of an ethanol-producing bacterium into ethanol, said carbohydrate being presented to said cells in a medium which is nutritionally inadequate for growth of said cells by lacking at least one factor required therefor.
In a process for producing ethanol by conversion of a substrate using cells of a bacterium, the improvement which comprises immobilizing said cells and converting said substrate in a non-fermentative manner by dissolving said substrate in water to give a medium which lacks at least one factor required for growth of the bacterium, and contacting said medium with said immobilized cells to effect said conversion.
