Abstract This study aimed to evaluate the potential of using a carbohydrate-rich microalga Chlorella vulgaris FSP-E as feedstock for bioethanol production via various hydrolysis strategies and fermentation processes. Enzymatic hydrolysis of C. vulgaris FSP-E biomass (containing 51\% carbohydrate per dry weight) gave a glucose yield of 90.4\% (or 0.461 g (g biomass)(-1)). The SHF and SSF processes converted the enzymatic microalgae hydrolysate into ethanol with a 79.9\% and 92.3\% theoretical yield, respectively. Dilute acidic hydrolysis with 1\% sulfuric acid was also very effective in saccharifying C. vulgaris FSP-E biomass, achieving a glucose yield of nearly 93.6\% from the microalgal carbohydrates at a starting biomass concentration of 50 g L(-1). Using the acidic hydrolysate of C. vulgaris FSP-E biomass as feedstock, the SHF process produced ethanol at a concentration of 11.7 g L(-1) and an 87.6\% theoretical yield. These findings indicate the feasibility of using carbohydrate-producing microalgae as feedstock for fermentative bioethanol production. Copyright © 2012 Elsevier Ltd. All rights reserved.
