“…En nutrición animal, además, es utilizada la harina de pescado como fuente no sólo de proteína, también de EPA y DHA, ya que la grasa residual (8%) que contiene esta harina tiene un alto contenido de AGPICL omega-3 (11).…”

Omega-3 long-chain polyunsaturated fatty acids (omega-3 LCPUFA) EPA and DHA, are currently considered of nutritional importance due the numerous positive health effects observed from its administration both in human and animal nutrition. However, sources to provide these fatty acids for supplementation are not abundant, being mainly fi sh oil in the case of humans and fi sh meal and fi sh oil in the case of animals, the main nutritional sources of omega-3 LCPUFA. However, fi sh meal and fi sh oil are products that have begun to diminish its availability primarily due to overexploitation of the fi sh resource, which currently produces a high cost of these products. Some vegetable oils contain alpha-linolenic acid, which is also an omega-3 fatty acid and the precursor of omega-3 LCPUFA, but that does not replace EPA and DHA in their nutritional effects. More recently microalgae have emerged as a renewable alternative for obtaining of omega-3 LCPUFA, mainly for its composition of EPA and/or DHA and good extractive yielding. These microorganisms can be artifi cially cultivated at industrial scale and properly processed as such (lyophilized, microencapsulated) or the oil and/or phospholipids extracted from these organisms (expended as such or microencapsulated), can be used for be added to a variety of foods for humans and animals feed (pets, animal feedlots, fi sh farming, among others). This paper analyzes the potential for the use of microalgae as source of omega-3 LCPUFA for human and animal nutrition.

“…In addition, the intracellular cholesterol presents a significant relation with the DHA concentrations (R 2 = 0.961; p = 1.207 × 10 −7 ), so this is another precedent in favor that synthesized DHA of this strain could be a phospholipid. It has been reported that cholesterol presents a high interaction with phospholipids when determined in marine species [41]. No relationship was observed between cholesterol and phosphorus in NCYC 1146; however, the main product in this strain is not DHA but carotenoids.…”

Due to the overexploitation of industrial fisheries, as the principal source of fish oil, as well as the increasing replacement of synthetic pigments for animal nutrition, we need to find sustainable sources for these essential nutrient productions. Marine Rhodotorula strains NCYC4007 and NCYC1146 were used to determine the biosynthesis of docosahexaenoic acid (DHA) and carotenoids by biotransforming raw glycerol, a waste product of biodiesel. To evaluate the presence of inhibitory substances in raw glycerol, both strains were also grown in the presence of analytical grade glycerol and glucose as the main carbon source separately. With raw glycerol, NCYC4007 showed a significant correlation between DHA production and intracellular phosphorous concentrations. NCYC1146, a new Rhodotorula strain genetically described in this work, can produce canthaxanthin but only when glycerol is used as a main carbon source. Then, NCYC4007 could synthesize DHA as a phospholipid, and the production of canthaxanthin depends on the kind of carbon source used by NCYC1146. Finally, malate dehydrogenase activity and glucose production can be used as a proxy of the metabolisms in these marine Rhodotorula. This is the first evidence that marine Rhodotorula are capable of synthesizing DHA and canthaxanthin using an alternative and low-cost source of carbon to potentially scale their sustainable production for animal nutrition.

“…Los aceites de pescado contenidos en las cápsu-las de omega 3 están compuestos principalmente por triglicéridos, los cuales tienen como característica principal su condición apolar al contener mayor cantidad de ácidos grasos y por esta razón no pueden ser directamente incorporados en matrices principalmente acuosas, haciendo que su uso como vehículo de suplementación de LC-PUFAs sea muy limitado (37). También debe tenerse en cuenta la posibilidad de que algunos de los encapsulados que se encuentran en el mercado declaren una cantidad de EPA y DHA en su etiqueta que puede no coincidir con su contenido real, pues estos productos son susceptibles a la isomerización térmica y a la degradación oxidativa de sus ácidos grasos (38).…”
