In the microalgae industry, the extraction of microalgae oil is an important process because it involves high energy consumption and high cost. At present, the main microalgae oil extraction methods are mechanical pressing [ 25 ], supercritical fluid extraction [ 27 ], enzyme extraction [ 43 ], and organic solvent extraction [ 7 ].
How to extract oil from algae Spirogyra?
Conclusion The extraction of oil from the algae Spirogyra was carried out using the (Solid –liquid) solvent extraction method using Soxhlet apparatus. From the experimental results obtained, the size factor considered for the oil extraction showed that finer the size of algae, more the contact between solvent producing high amount of oil content.
What apparatus is used to extract oil from algae?
In the present research, the apparatus used for the extraction of oil from the algae was Soxhlet apparatus. This apparatus is commonly used for extraction of compound when the solubility level in solvent is low, and the impurities getting immiscible with the solvent. The layout of the Soxhlet extractor apparatus is shown in the Fig. 5.
Can methanol extract microalgae oil?
To verify the impact of complex solvents, two and three of methanol, water, and chloroform were mixed to extract microalgae oil. It’s notable to find that after adding methanol or water into chloroform, the microalgae oil extraction yield was greatly raised to 34.6% and 43.3%.
How to extract oil from Algae powder?
It is in general known as liquid- liquid extraction and partitioning. In this present work, algae powder was mixed with n-Hexane to extract the oil from it. The oil extraction followed two basic steps; in step (i) the algae powder was allowed to mix with n-hexane to initiate the reaction.
Can microalgae be extracted from wet biomass?
In the case of microalgae, the solvent is generally added to dry biomass, although the utilization of wet biomass can decrease the overall cost of the process because it is an energy-saving extraction procedure with the disadvantage that usually affects the separation process causing a low extraction efficiency ( Xu et al., 2021 ).
