Abstract
The present invention provides a method for decreasing the fermentation inhibition in a fermentation of cellulose-derived material in a fermentor, wherein fermentation inhibitory properties of the material subjected to fermentation is decreased by an addition of at least one reducing agent to the fermentor. Further, there is provided a method of increasing the fermentability of a fermentation process comprising the steps of measuring the fermentability of the fermentation process and if the fermentability is below a reference value, then adding at least one reducing agent to the fermentation process.
Claims6
A method of increasing the fermentability of a process of fermenting cellulose-derived material to ethanol, butanol or succinic acid, wherein yeast is used as the fermenting organism, comprising the steps of
- a) measuring the fermentability of said fermentation process and if said fermentability is below a reference value, then
- b) adding at least one reducing agent to said fermentation process.
