Bioenergies could replace fossil energies and reduce its greenhouse gas emission. A production of biodiesel via transesterification of triacylglycerides (TAGs) would benefit environment by producing sustainable energies from reproducible resources. Lipids from microalgae can be effective feedstocks for making bioenergies but lipids extraction and conversion operation are the high cost steps for producing biofuel from microalgae. Additionally, the dewatering process of microalgae before lipid extraction is one of the high-cost steps in microalgal biodiesel production. In this study we developed effective dewatering method, and biodiesel production process for Dunaliella tertiolecta. As a result, wet biomass was directly used as feedstock, the suggested process led to 54% reduced cost of biodiesel production, low lipid loss (0.87%, based on total lipid) and same FAMEs (fatty acid methyl esters) production yield of conventional (dry route) biodiesel method.
