title: Investigation of utilization of the algal biomass residue after oil extraction to lower the total production cost of biodiesel.
abstract: In this study, component analysis of a novel biodiesel-producing alga, Pseudochoricystis ellipsoidea, was performed. The component analysis results indicated that proteins and amino acids are abundant in P. ellipsoidea while the sugar content is relatively low. Rather than its use as a carbon source, the use of the algal biomass residue after oil extraction as a nutrient source provided a new way for lowering the total production cost of biodiesel. In both lactic acid and ethanol fermentations, the use of the residue instead of high-cost nutrient yeast extract allowed a significant saving, showing the promise of the algal biomass residue for use as a fermentation nutrient source.
