Abstract

Massive interests to microalgal biodiesel are obvious to date, due to the promising prospect of microalgae as biodiesel feedstock. Nevertheless, based on the result of energy analyses and life- cycle assessments, microalgal biodiesel production has consumed large amount of energy and it has not been cost effective yet. Therefore, utilization of lipid-extracted microalgal biomass residues (LMBRs), one kind of residues produced after lipid extraction in biodiesel production should be effectively investigated. This work emphasizes on the overview of researches related to the biochemical characterization of LMBRs. The LMBRs of Dunaliella tertiolecta (UTEX LB 999) consisted of total carbohydrates of 82.0%, proteins of 13.4%, and ash of 4.5% (w/w in dry mass). Meanwhile, D. tertiolecta LB 999 LMBRs contained carbohydrate of 60%, and its saccharification yield was 42% based on LMBRs mass. Moreover, the biochemical composition of Haematococcus pluvialis LMBRs were crude fiber (9.6%), crude protein (40.3%), and crude lipid (0.9%) while Scenedesmus sp. LMBRs contained carbohydrate (24.7%), protein (32.4%), lipid (6.5%) and ash (10.0%). Keywords: microalgal, biodiesel, LCA, LMBRs, characterization, EPS, saccharification
