摘要：
When Chlorella biomass was hydrolyzed in the presence of 2% HCl and 2.5% MgCl2, a sugar concentration of nearly 12%, and a sugar recovery of about 83% was obtained. Fermentation experiments demonstrated that glucose in the Chlorella biomass hydrolysates was converted into ethanol by Saccharomyces cerevisiae with a yield of 0.47 g g(-1), which is 91% of the theoretical yield. This chemical hydrolysis approach is thus a novel route for the hydrolysis of biomass to generate fermentable sugars. (c) 2011 Elsevier Ltd. All rights reserved.
