Evaluation of Different Routes for Obtaining Biofuels and High Value Products from Microalgae under Biorefinery Concept

摘要

A biorefinery uses all biomass components for obtaining high value usable products. In the present study, the authors defines routes for obtaining monosaccharides and lipids from microalgae biomass of the Amphiprora sp. and Navicula sp., The routes were evaluated and compared based on the extraction efficiency and sugars concentration obtained. For acid hydrolysis -Soxhlet extraction, several times of acid hydrolysis and extraction were evaluated. For Organosolv-Soxhlet extraction route, lipid efficiency obtained was 48% and for Polyfunctional Process the highest percentage of reducing sugars was 1.67 mg/mL. FTIR was used for compare oil extracted and biodiesel. Under biorefinery concept, Polyfunctional process route shows the best performance for obtaining several products of microalgae.
