Freshwater algae are a source of unsaturated fatty acids, essential for healthy development of the human body. Green microalga chlorella vulgaris was selected for laboratory extraction of the lipid fraction, especially with regard to the content of fatty acids. Owing to that microalgae consist of individual cells surrounded by the thick cell walls, several cell-disruption methods were applied to increase the lipid extraction efficiency. The concentrated algal biomass suspension was disrupted using methods as follows: drying, lyophilisation, microwave treatment, sonication and high-pressure shock. Mild extraction conditions (room temperature, absence of light, environmental friendly solvent system) were applied.
