[ Sen. 1, subscore: 1.00 ]: Corn cob hydrolysates , with xylose as the dominant sugar , were fermented to ethanol by recombinant Escherichia coli KO11 . When inoculum was grown on LB medium containing glucose , fermentation of the hydrolysate was completed in 163 h and ethanol yield was 0 . 50 g ethanol/g sugar . When inoculum was grown on xylose , ethanol yield dropped , but fermentation was faster ( 113 h ) . Hydrolysate containing 72 . 0 g/l xylose and supplemented with 20 . 0 g/l rice bran was readily fermented , producing 36 . 0 g/l ethanol within 70 h . Maximum ethanol concentrations were not higher for fermentations using higher cellular concentration inocula .
