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?
1. Mechanical Pressing Mechanical pressing involves the application of pressure to break algal cell walls and release the oil content. This method is widely used for extracting oil from various plant sources, including algae.
What are the most common algae harvesting techniques and oil extraction methods?
Several harvesting techniques and oil extraction methods have been developed to optimize algae cultivation and increase the efficiency of biofuel production. This article discusses some of the most common algae harvesting techniques and efficient oil extraction methods used in the biofuel industry. 1. Flocculation
How is algal biomass extracted?
Extraction of algal biomass consists of the following steps: pretreatment, extraction, formulation. Since algal biomass does notcontainlignin,butcellulose,extractionofbiologicallyactive compounds is facilitated . Nevertheless, high content of cell wall polysaccharides complicates the extraction of metabolites from algae .
