Recent advances in enhancing the production of long chain omega-3 fatty acids in microalgae

Critical Reviews in Food Science and Nutrition, Journal Year: 2023, Volume and Issue: 64(29), P. 10564 - 10582

Published: June 26, 2023

Omega-3 fatty acids have gained attention due to numerous health benefits. Eicosapentaenoic (EPA) and docosahexaenoic acid (DHA) are long chain omega-3 produced from precursor ALA (α-linolenic acid) in humans but their rate of biosynthesis is low, therefore, these must be present diet or should taken as supplements. The commercial sources limited vegetable oils marine sources. rising concern about vegan source, fish aquaculture conservation heavy metal contamination has led the search for alternative source. Microalgae importance production high-value EPA DHA can thus serve a sustainable promising source acids. Although bottleneck lies optimization enhanced that involves strategies

Omega-3 fatty acids, including alpha-linolenic acids (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic (DHA), have shown major health benefits, but the human body’s inability to synthesize them has led necessity of dietary intake products. The omega-3 market grown significantly, with a global from an estimated USD 2.10 billion in 2020 predicted nearly 3.61 2028. However, obtaining sufficient supply high-quality stable can be challenging. Currently, fish oil serves as primary source market, it several drawbacks, high cost, inconsistent product quality, uncertainties its sustainability ecological impact. Other significant sources include plants microalgae fermentation, they face similar challenges reducing manufacturing costs improving quality sustainability. With advances synthetic biology, biotechnological production via engineered microbial cell factories still offers best solution provide more stable, sustainable, affordable by overcoming issues associated conventional sources.

The importance of essential fatty acids and their ratios in aquafeeds to enhance salmonid production, welfare, and human health

Frontiers in Animal Science, Journal Year: 2023, Volume and Issue: 4

Long chain polyunsaturated fatty acids (LC-PUFA), namely those from omega-3 (n-3) and omega-6 (n-6) families, are paramount for both fish human nutrition. Some of these biomolecules cannot be synthesized de novo must acquired through the diet, being termed dietary essential (EFA). Fish requirements EFA have traditionally been met incorporation oil (FO) in formulation aquafeeds. However, with limited supply FO aquaculture industry is searching additional sustainable sources LC-PUFA. This has significantly shifted type ingredients used aquafeed formulation, vegetable oils (VO) deficient long-chain omega-3, often resulting imbalanced levels ratios acid classes. Such imbalances can negatively affect performance welfare, as well health promoting LC-PUFA present fillets. Given relevance that salmonid plays global production (principally Atlantic salmon, Salmo salar ), its growing role a source humans, review summarizes scientific knowledge available to date on by salmonids humans. We discuss implications using formulations upon subsequent consequences nutrition, along current efforts replace alternative such algal (AO) safeguard high-quality products consumption.

Marine Animal Co-Products—How Improving Their Use as Rich Sources of Health-Promoting Lipids Can Foster Sustainability

Marine Drugs, Journal Year: 2024, Volume and Issue: 22(2), P. 73 - 73

Published: Jan. 30, 2024

Marine lipids are recognized for their-health promoting features, mainly being the primary sources of omega-3 fatty acids, and therefore critical human nutrition in an age when global supply these nutrients is experiencing unprecedent pressure due to ever-increasing demand. The seafood industry originates a considerable yield co-products worldwide that, while already explored other purposes, remain mostly undervalued as sustainable healthy lipids, often low-value oil production. These especially appealing lipid since, besides well-known nutritional upside marine animal fat, which particularly rich polyunsaturated they also have interesting bioactive properties, may garner them further interest, not only food, but high-end applications. Besides added value that represent valuable sources, there obvious ecological reducing waste. In this sense, repurposing bioresources will contribute more use strain on heavily depleted stocks. Therefore, untapping potential aligns with both health environmental goals by guaranteeing additional eco-conscious practices.

Abstract Microalgae are considered to be a promising group of organisms for fuel production, waste processing, pharmaceutical applications, and as source food components. Unicellular algae worth being because their capacity produce comparatively large amounts lipids, proteins, vitamins while requiring little room growth. They can also grow on fix CO2 nitrogen compounds. However, production costs limit the industrial use microalgae most profitable applications including micronutrient fish farming. Therefore, novel based technologies require an increase efficiencies or values. Here we review recent studies focused getting strains with characteristics cultivating techniques that improve production's robustness efficiency categorize these findings according fundamental factors determine Improvements light nutrient delivery, well other aspects photobioreactor design, have shown highest average in productivity. Other methods, such improvement phosphorus fixation temperature adaptation been found less effective. Furthermore, interactions particular bacteria may promote growth microalgae, although bacterial grazer contaminations must managed avoid culture failure.
