Our previous study reported the extraction of lipids from raw sewage sludge for biodiesel production. This study demonstrates application of the residue, lipid-extracted sewage sludge (LESS) with 8.9% carbohydrate, to obtain sugars for bioethanol production. Enzymatic saccharification was adopted to process the LESS, while a mixture of two widely used commercial enzymes (Celluclast and Viscozyme at a mixing volume ratio of 2:1) was shown to be the most effective among the individual enzymes and enzyme mixtures at various mixing ratios. By statistical optimization of enzymatic saccharification process, a sugar yield of 72.0% was obtained from the LESS under the following optimal conditions: 1188.6 μL of enzyme mixture/g-LESS at 50.0℃ and a reaction time of 37.1 h. Using 5.0 and 10.0 g/L solutions of sugars obtained from LESS via enzymatic saccharification under the optimal conditions, 1.91 and 3.31 g/L bioethanol were obtained after 18 h of fermentation, respectively.
