“…Due to the strong interaction among anions, cations, and other molecules, ILs have impacts on different degrees of life substances, from single proteins to intricate multicellular organisms. 7,[135][136][137][138][139] The interaction of ILs with biological systems has opened up a broad prospect for their application in biomedicine. In this section, we summarize the effects of ILs on cell membranes, organelles, nucleic acids and proteins.…”

“…187 MAE can break the cytoderm and heat cells to accelerate the dissolution of intracellular effective components. 135 Therefore, IL-MAE can depend on cell penetration and selective heating to help ILs in extracting drug components from plant raw materials. For example, Komaty et al used ILs with MAE to extract atranorin, methyl-b-orcinol carboxylate, fumarprotocetraric acid and physodic acid from lichens more rapidly than when using conventional heating.…”

This work focused on the potential of simultaneously removing ammonium nitrogen from industrial wastewater using immobilized microalgae and powdered zeolite. Experiments were performed with different species and doses of microalgae embedded in spherical hydrogels in semicontinuous conditions. Ammonium nitrogen uptake by microalgae promoted the slow release of previously adsorbed ammonium nitrogen from zeolite that was then also absorbed by microalgae. Results showed that immobilized microalgae can reach a removal efficiency of up to 60% (C. vulgaris) and 42% (S. armatus). A higher removal efficiency was obtained for zeolites and immobilized C. vulgaris or S. armatus up to 86% and 79%, respectively. Moreover, a higher maximum sorption capacity for C. vulgaris (13.8 mg/g) was achieved than for S. armatus (5.5 mg/g). The recycling of spent hydrogel, zeolite, and wastewater is possible. Such an approach represents a circular bioeconomy loop.

“…Microalgae have long been known to be a source of several compounds with quite interesting properties. As such, microalgae or its extracts have diverse applications in different areas, such as human nutrition, feed in aquaculture, biofertilizers, treatment of effluents, and even in human health [ 1 , 2 , 3 ]. Bioactive compounds present in microalgae include lipids, namely polyunsaturated fatty acids (PUFA), which are probably the most studied amongst compounds, sterols, pigments, proteins, enzymes, vitamins and other compounds with biological activity [ 2 , 3 , 4 ].…”

“…In order to obtain the compounds of interest from microalgae cells, present in the cell wall itself or intracellularly, extraction must be performed [ 3 , 17 ]. The main objective of extraction techniques is to obtain a high yield of the desired compounds without jeopardizing quality and activity, as well as to preserve co-products, minimize the amount of energy spent and waste generation, optimize the process (operational temperature, pressure, carrying capacity, side reactions and separations) and be scalable [ 18 ].…”

Extraction of Nannochloropsis Fatty Acids Using Different Green Technologies: The Current Path

et al. 2023

View full text Add to dashboard Cite

Nannochloropsis is a genus of microalgae widely recognized as potential sources of distinct lipids, particularly polyunsaturated fatty acids (PUFA). These may be obtained through extraction, which has conventionally been performed using hazardous organic solvents. To substitute such solvents with “greener” alternatives, several technologies have been studied to increase their extraction potential. Distinct technologies utilize different principles to achieve such objective; while some aim at disrupting the cell walls of the microalgae, others target the extraction per se. While some methods have been utilized independently, several technologies have also been combined, which has proven to be an effective strategy. The current review focuses on the technologies explored in the last five years to extract or increase extraction yields of fatty acids from Nannochloropsis microalgae. Depending on the extraction efficacy of the different technologies, distinct types of lipids and/or fatty acids are obtained accordingly. Moreover, the extraction efficiency may vary depending on the Nannochloropsis species. Hence, a case-by-case assessment must be conducted in order to ascertain the most suited technology, or tailor a specific one, to be applied to recover a particular fatty acid (or fatty acid class), namely PUFA, including eicosapentaenoic acid.
