KeywordsDeep eutectic solvents
Microalgae are a vast group of autotrophic microorganisms whose metabolic diversity makes them a natural source of valuable organic compounds such as lipids, carbohydrates, proteins, vitamins, and bioactive molecules. Several microalgae species contain notable amounts of polyunsaturated fatty acids, particularly eicosapentaenoic acid (EPA), which is an important alpha-linolenic acid derivative for human health. Conventional methods are considered effective at recovering total lipids from microalgae, however, they imply the use of large volumes of organic solvents such as methanol and chloroform, which are toxic and pose environmental risks. Thus, it is necessary to find new methods involving sustainable and green extracting phases. Deep eutectic solvents (DES) are renewable compounds often formed, but not exclusively, by quaternary ammonium salts and non-hydrated metal halides. Due to their availability, low cost, biodegradability, and environmental friendliness, DES are a promising ...
