Utilization of sustainable natural resources such as microalgae has been considered for the production of biofuels, aquaculture feed, high‐value bioactives such as omega‐3 fatty acids, carotenoids, etc. Eicosapentaenoic acid (EPA) is an omega‐3 fatty acid present in fish oil, which is of physiological importance to both humans and fish. Marine microalgae are sustainable sources of lipid rich in EPA, and different species have been explored for the production of EPA as a single product. There has been a rising interest in the concept of a multi‐product biorefinery, focusing on the maximum valorization of the algal biomass. Targeting one or more value‐added compounds in a biorefinery scenario can improve the commercial viability of low‐value products such as triglycerides for biofuel. This approach has been viewed by technologists and experts as a sustainable and economically feasible possibility for the large‐scale production of microalgae for its potential applications in biodiesel and jet fuel production, nutraceuticals, animal and aquaculture feeds, etc. In this review paper, we describe the recent developments in the production of high‐value EPA‐rich oil from microalgae, emphasizing the upstream and downstream bioprocess techniques, and the advantages of considering an EPA‐rich oil‐based biorefinery.

“…A study showed that mushroom chitosan could be an efficient flocculating agent with more than 95% efficiency for Nannochloropsis spp. [221] Other alternatives include Moringa oleifera seed extract, which has been proven to be an effective coagulating agent for removing Chlorella, Microcystis, Oocystis, and Scenedesmus. [222] Combinations of harvesting techniques are often used to reduce the overall cost of the harvesting process.…”

The world population is ever increasing and so is the need to ensure food security. Food production needs to increase by about 70% within the next 40 years to cater for food consumption. Moreover, with increasing collective consciousness toward food supplementation for improving quality of health, the development of nutraceuticals has gained prominence in disease prevention, treatment, and overall health improvement. However, due to the constant controversial debate of food production for consumption against other uses, the search for better alternatives led to microalgae. Species such as Spirulina, Chlorella, Scenedesmus, and Dunaliella, among many others, are important sources of primary and secondary metabolites that play crucial roles in disease prevention and treatment. Understanding the significance of nutraceuticals and how microalgae can be used to produce those value-added molecules is necessary for any potential commercial exploitation. This review discusses the potential of microalgae to be exploited as promising sources of nutraceuticals. Here, essential biomolecules used as nutraceuticals are explored and their crucial roles in disease prevention, especially cancer, cardiovascular diseases, and strengthening the immune system. The composition of microalgae, which makes them suitable candidates to produce nutraceuticals, is discussed. Furthermore, the multifarious aspects of microalgae cultivation, in terms of cultivation systems and factors affecting biomass production and productivity regarding nutraceutical production, are reviewed. The multiple sustainable facets of microalgae culture, which can help in carbon sequestration, fast biomass production, and boosting health benefits, should interest stakeholders and potential commercial producers. Bioprocessing of microalgae for the extraction and purification of microalgae-based products is also reviewed, focusing on the key methods of pre-treatment, extraction, and purification of microalgal biomass.
