METHODS FOR PRODUCING FERMENTATION PRODUCTS

摘要

The invention relates to methods for producing a fermentation product from a lignocellulose-containing material comprising i) pre-treating lignocellulose-containing material; ii) hydrolysing pre-treated lignocellulose-containing material; iii) fermenting using a fermenting organism; wherein fermentation is initiated and carried out at: a) a fermentation organism cell count in the range from 10-250x1010 cells per L fermentation medium; or b) a fermentation organism concentration in the range from 2-90 g dry weight fermenting organism per L fermentation medium.
