| 摘要 | The conversion of lipid-extracted microalgal biomass residues (LMBRs) into hydrogen plays the dual role in renewable energy production and sustainable development of microalgal biodiesel industry. An anaerobic fermentation process to covert LMBRs into hydrogen was investigated in this work. Using batch experiments, the effects of pretreatment of inoculum (by acid, base, heat, and chloroform, respectively), initial pH (5.0-7.0). inoculum concentrations at 0.59-2.94 g VSS/I (volatile suspended solids. VSS) and substrate concentrations at 4.5-45 g VS/I (volatile solids, VS) were investigated, respectively. The results showed that the most effective hydrogen production was obtained from fermentation of LMBRs with a concentration of 36 g VS/I at the initial pH 6.0-6.5 using the heat-treated anaerobic digested sludge as inoculum. Acetate. propionate and butyrate were the main fermentation byproducts in the conversion of LMBRs into hydrogen. (C) 2010 Elsevier Ltd.
