Extraction methods of algae oils for the production of third generation biofuels
Microalgae offer several advantages for the biodiesel production mainly in terms of their high growth rate and lipid composition, which is in the 15–70 wt% range of the biomass on a dry basis (Shin et al., 2018; Wahidin et al., 2018; Kanda et al., 2020; Shahi et al., 2020; Yin et al., 2020; Calijuri et al., 2022).).
To efficiently convert the microalgae to valuable and renewable fuels, the microalgae oil was first extracted and then transformed into the second-generation biodiesel. Among all solvents that were used for the microalgae oil extraction, the polar single solvent system methanol achieved the optimal value (47.8% extraction yield) because the polar cell membrane was easily dissolved by the polar
Bio-oil from microalgae: Materials, production, technique, and future
Bio-oil upgrading is the elimination of nitrogen from algal bio-oil or oxygen from bio-oil (Oasmaa et al., 2021). The deoxygenation is facilitated by the decarbonylation and decarboxylation at a temperature of about 400 °C, while deoxygenation is facilitated through dehydration at a temperature of about 250 °C on catalytic transformations of acetic acid and acetone ( Bhoi et al., 2020 ).
Microalgae oil can be extracted from the microalgal biomass and converted into biodiesel, whose calorific value is 42 MJ/kg, compared to gasoline with a calorific value of 46 MJ/kg [18, 19]. However, the type of technology for the economical production of microalgae biofuel has been actively debated.
Extraction of lipids from microalgae using classical and innovative approaches
This review aims providing an overview of classical and innovative approaches for lipids extraction from microalgae, based on existing studies, while aims to explore the effects of different approaches on its yield and biological activity, so as to develop its application potential. 2.
Moreover, with a lower annual operating cost of $37–$42.65 million and lipid yielding a cost of $13/gal, ORPs represent a more cost-effective microalgae cultivation method than PBRs, which have an annual operating cost of $55–$62.80 million and lipid yielding a cost of $33/gal ( Chen, 2017 ).

On the other hand, lipids extracted from microalgae can also be used as food additives to supply additional nutritive factors in human food. The study on the extraction of DHA from Thraustochytrium sp. biomass reported 1-ethyl-3-methylimidazolium ethylsulfate and tetrabutylphosphonium propionate, with the use of IL:methanol at 1:10 and 1:4 ratio, respectively, achieved lipid extraction yield
Microalgal biomass is a sustainable source of bioactive lipids with omega-3 fatty acids. The efficient extraction of neutral and polar lipids from microalgae requires alternative extraction methods, frequently combined with biomass pretreatment. In this work, a combined ultrasound and enzymatic process using commercial enzymes Viscozyme, Celluclast, and Alcalase was optimized as a pretreatment
Microalgae Oil Extraction Pre-treatment Methods: Critical Review and Comparative Analysis, Semantic Scholar
Microalgae biomass can be used to produce numerous value added products such as biodiesel, bioethanol, biogas, biohydrogen, fish feed, animal feed, human food supplements and skin care products. Production of value added products from microalgae biomass requires the growth and recovery of the algae biomass, extraction and downstream processing of the desired product. One of the major obstacles
Mechanical methods are widely used for the extraction of oil from microalgae, since the cell wall is broken through physical force, allowing the oil to escape. The efficiency of this technique depends on the microalgae species, for example, in Spirulina sp., cell rupture is easy since it does not have a rigid cell wall, while Chlorella sp. has a rigid cell wall [ 27 ].
