haematococcus pluvialis, astaxanthin

Natural Source Astaxanthin. Haematococcus pluvialis is a unicellular green alga and is considered as the best natural resource for astaxanthin, which is a high-value carotenoid with strong biological activity for the food, feed, and pharmaceutical industries (Ambati et al. P.D. Among various natural sources, Haematococcus is an exclusive producer of astaxanthin (pink carotenoid). Effects of astaxanthin-rich Haematococcus pluvialis extract on cognitive function: a randomised, double-blind, placebo-controlled study. Haematococcus pluvialis is a freshwater species that is well known for its high content of the strong antioxidant astaxanthin, which is important both in aquaculture and cosmetics. J. Oehlenschläger, U. Ostermeyer, in Handbook on Natural Pigments in Food and Beverages, 2016. Vegetative green cells are usually produced in closed photobioreactors and then the culture is exposed to high irradiance in open systems under nutrition stress (usually nitrogen deficiency) to induce astaxanthin synthesis (up to 5% of dry weight) within 3–5 days. Haematococcus pluvialis (Chlorophyta) is a freshwater, unicellular green microalga with a rather complex life cycle. The actual production costs are still too high to compete with synthetic equivalents. ASTAXANTHIN is a deep red-colored phytonutrient synthesized by microalgae called Haematococcus Pluvialis. The freshwater green microalga Haematococcus pluvialis has been receiving much attention recently because of its capacity to accumulate very high levels of the carotenoid astaxanthin (Aflalo et al., 2007). J Clin Biochem Nutr. (2008) have reported that a diet deficient of lutein and DHA increases the risk of cognitive decline in the elderly. Astaxanthin from Haematococcus pluvialis ameliorates the chemotherapeutic drug (doxorubicin) induced liver injury through the Keap1/Nrf2/HO-1 pathway in mice† Haotian Ma , a Shuaihang Chen , a Huaye Xiong , b Meng Wang , a Wei Hang , a Xiaoli Zhu , a Yubin Zheng , c Baosheng Ge , d Runzhi Li * a and Hongli Cui * ae (2015) have shown that Nannochloropsis sp. In this process, conditions are first optimized for the growth of the non-carotenogenic flagellate cells to achieve the maximum biomass, followed by a stage, in which the cells are “stressed” to induce aplanospore formation and maximize astaxanthin accumulation. H. pluvialis undergoes significant morphologic changes from green active cell to red immobile cell, which make the cultivation conditions different to maximize the energy availability according to light efficiency and enzyme reaction 12 , 13 . 2014). In another study, lutein has been reported to accumulate in brain regions rich in PUFAs present in the membrane. Secondary metabolites are not required for survival, but generated as a protective mechanism by these lifeforms. Astaxanthin can pass through the blood-brain barrier to extend its powerful antioxidant benefits to the whole body system. In nature H. pluvialis is found in shallow temporary water bodies such as depressions in rocks and bird baths. Sudipta Saha, ... Siddhartha Maity, in Ingredients Extraction by Physicochemical Methods in Food, 2018. Three-dimensional ultrastructural study of oil and astaxanthin accumulation during encystment in the green alga, Borowitzka et al., 1991; Boussiba, 2000; Fábregas et al., 2003, Carotenoid Production Using Microorganisms, Feed Additives for Influencing the Color of Fish and Crustaceans, Handbook on Natural Pigments in Food and Beverages, Modern Extraction Techniques for Drugs and Medicinal Agents, Ingredients Extraction by Physicochemical Methods in Food. There are now many companies growing H. pluvialis as a source of the carotenoid astaxanthin. DIC: differential interference contrast image; Cells stained with the nucleus stain SYBR Green (green)—SYBR Green stains nuclei; CHL: chlorophyll autofluorescence (red); and Overlay: overlaid images of SYBR and CHL. The cells then develop into an aplanospore with a thick algeenan-containing cell wall and become quite red due to massive accumulation of astaxanthin-containing lipid droplets which eventually fill the whole cytoplasm. Carotenogenesis is stimulated by a wide range of “stress” factors, such as nutrient limitation, especially N-limitation; high light; high temperatures; or NaCl addition (Borowitzka et al., 1991; Boussiba & Vonshak, 1991; Fan et al., 1994; Cordero et al., 1996): in fact almost any factor that inhibits growth. Astaxanthin, which is primarily derived from organic sources such as the shells of organic crustacean, may be used within the limit of the physiological needs of the fish. The optimum growth temperature is between 15-20ºC, and, in batch culture, the motile stage predominates during the logarithmic phase of growth, whereas the carotenogenic aplanospores are formed during stationary phase. Michael A. Borowitzka, in Microalgae in Health and Disease Prevention, 2018. Suction pipettes have been widely used for recording photocurrents from animal photoreceptor cells (Baylor et al., 1979). Astaxanthin protects primary hippocampal neurons against noxious effects of Aβ-oligomers. A recent study on treated group showed a lower level of blood glucose as compare with the non consume astaxanthin group. IFF, fast flagellar current, IFS, slow flagellar current. J. Masojídek, G. Torzillo, in Reference Module in Earth Systems and Environmental Sciences, 2014. The astaxanthin is accumulated in droplets in the perinuclear cytoplasm in the aplanospore stage of the life cycle and occurs as the 3S, 3′S isomer in the form of free astaxanthin, as well as mono- and di-esters with C16:0, C18:0, C20:0, and C18:1 fatty acids (Grung et al., 1992). 2012;51:102-7. EAE was extracted from the red microalgae through supercritical fluid carbon dioxide extraction. 12. That is to say, scientists have discovered Astaxanthin to neutralize and mop up these free radicals. A Chlamydomonas cell sucked into a glass electrode for photocurrent measurements. Further to this, it also suppresses NO, PGE2, and TNF-α production, through directly blocking NOS enzyme activity (Ohgami et al., 2003). From decades of research in nutrition and healthy living, everybody understand the important of getting enough antioxidants in our diet, whether from food sources or supplements. ), astaxanthin (ASTA) > 5%, The Strongest antioxidants Supplement, Free Radical scavenging on … It enters the green motile stage under favorable environmental conditions. Katagiri M, et al. “Green microalgae” comprise more than 7000 species growing in a variety of habitats. Buy Pure Haematococcus pluvialis Extract Powder, 1000 Grams (35 Oz. Antioxidant role of astaxanthin in the green alga Haematococcus pluvialis. Kalyani H. Barve, ... Anil B. Gaikwad, in Fruits, Vegetables, and Herbs, 2016. Peter Hegemann, Peter Berthold, in The Chlamydomonas Sourcebook, 2009. Lobos P et al. Johnson et al. It will be worth to reiterate again that microalgae such as Chlorella sp. Refresh: when old cultures are transplanted into fresh medium, coccoid cells undergo cell division to form flagellated cells within the mother cell wall. Haematococcus pluvialis (Chlorophyta) is a freshwater, unicellular alga with a rather complex life cycle. Examples of such stressful conditions include high light and salinities, and the low availability of nutrients (Grünewald et al., 2001). Among many antioxidants that are used for the repairing of oxidative stress induced skin damages, we identified the enriched astaxanthin extract (EAE) from Haematococcus pluvialis as a viable ingredient. Green vegetative cells are usually produced in closed photobioreactors under an optimal light intensity and nutrient-replete medium. Haematococcus pluvialis is the richest source of natural astaxanthin (Guerin et al., 2003). An antioxidant is a substance that stops free radicals from causing cellular damage. Xanthophylls such as lutein, zeaxanthin, and cryptoxanthin have been shown to accumulate up to 77% in the human brain regions (Craft et al., 2004). This microalgae which are the primary diet of flamingos, salmon, shrimp, lobsters, krill, crabs and other aquatic animals gives them the vibrant orange-pink hue. Synthetic pigments are not permitted. This means that, consuming Chlorella supplements may decrease cognitive decline among the elderly too. Spores and motile cells are susceptible to photoinhibition and would die under photoinduction conditions. J. Masojídek, G. Torzillo, in Encyclopedia of Ecology, 2008. White arrow, flagella inside pipette; black arrow, eyespot outside the pipette; bar=8 μm. The actual production costs are still too high to compete with synthetic equivalents. As the culture continues, the flagellated cells then lose their flagella and round up, forming a rigid cell wall to form what is sometimes called a palmella stage. Increased astaxanthin production in several strains has also been achieved through mutagenesis (Chen et al., 2003) and genetic engineering (Steinbrenner & Sandmann, 2006), but better results have been obtained through the isolation and screening of new strains (Borowitzka, unpublished results). have high content of lutein and docosahexaenoic acid (DHA). In another study, low levels of lutein in red blood cells of an AD patient suggested the importance of neuroprotective lutein to prevent or delay the onset of AD (Kiko et al., 2012). Effect of astaxanthin-rich extract derived from Paracoccus carotinifaciens on cognitive function in middle-aged and older individuals. It protects the liver from oxidative damage and detoxifying enzymes in the liver cell thereby improving its function at removing harmful contaminants, bacteria, viruses and dead red blood cells. 11. This red color is caused by the astaxanthin, which is believed to protect the resting cysts from the detrimental effect of UV-radiation, while exposed to direct sunlight (Boussiba, 2000). High light irradiation is essential for astaxanthin accumulation in Haematococcus pluvialis. The mechanism of how lutein affects the brain has not been fully elucidated till now. The plastoquinone pool appears to function as a redox sensor, and reduction of the plastoquinone pool leads to the transcriptional activation of most, if not all, genes involved in astaxanthin biosynthesis (Steinbrenner, 2003). … Or they could be critical proteins within the cell or they would even be our DNA. The last configuration is not recommended since flagellar currents rapidly decline due to mechanical inactivation of the flagella. 7.3). This change in cell morphology—from rapidly dividing, shear sensitive flagellated cells to the extremely robust, non-motile aplanospores—means that, generally, a two stage, batch growth process is preferred (Cysewski & Lorenz, 2004; García-Malea et al., 2008). It possesses antioxidant activity due to which it is capable of inhibiting the production of inflammatory mediators by blocking NF-κB activation and as a consequence suppression of IkB kinase activity and IkB-α degradation (Lee et al., 2003). The biosynthesis of astaxanthin is usually accompanied by the transformation of ovoid green vegetative cells into red cysts under stress conditions (nutrient deficiency, salinity, and high temperatures, in combination with high irradiance), due to the increased carotenoid deposition. The two-stage strategy has been widely adopted to produce astaxanthin by the Haematococcus industry and research community. The cells are normally green but under stress conditions (nutrient deficiency, salinity, high temperatures in combination with high irradiance), the green vegetative cells produce thicker walls and change to globular cysts with a great increase in cell volume and pigmentation to orange-red, due to an increased carotenoid deposition. According to the scientific opinion of the Panel on Dietetic Products, Nutrition and Allergies (NDA), the product is to be considered as a novel food ingredient (NFI). Astaxanthin From Haematococcus Pluvialis Astaxanthin is an organic compound synthesized naturally by fungi, bacteria, and yeasts as a secondary metabolite. Photoreceptor currents recorded indirectly using suction pipettes (A) and directly from the eye using patch pipettes (B). These cells have a gelatinous extracellular matrix (periplasm) connected to the protoplast via thin penetrating cytoplasmic strands. There is a whole lot of science behind a study from 2005 which look into Astaxanthin and its potential role in prevention cancer. The maximum astaxanthin content of the cells is also strain dependent (Lee & Soh, 1991). This whole growth cycle takes several weeks (Boussiba et al., 1997; Olaizola, 2000; Cysewski & Lorenz, 2004). Finally, photoreceptor currents may be recorded directly from the eye when only the eye is sucked into a patch pipette with a steep cone angle (Ehlenbeck et al., 2002). (B) Illustration of life cycle of H. pluvialis. Among microalgae, Haematococcus pluvialis is well known for its high bioactive secondary metabolite (astaxanthin) and its complex cell life 11. In addition, astaxanthin has recently garnered commercial interest as a nutraceutical, cosmetic, and pharmaceutical. Some of these include poor vision eye sight, inflammation, heart disease antoimmune disease, cancer and diabetes, just name a few. Photoinduction using non-motile cells as seeds could result in a higher astaxanthin production than … The Haematococcus strains grow slowly at around 25–28 °C, and are prone to contamination by other microalgae. Therefore, a two-stage process is employed for biomass production. 2012;51(2):102-7. The results seemed to suggest that, once again the antioxdative activity of astaxanthin reduce the oxidative stress on the kidneys thus preventing renal cell damage. The reactors are cooled by evaporative cooling using water sprayed over the outside of the reactors. Many species of microalgae have been used as source of nutrient rich food, feed, and health promoting compounds. There is substantial evident that neurodegenerative disease like Alzheimer’s, Huntington’s, Parkinson’s and so on, one cause by oxidative damage to your nervous system. The Algatechnologies production plant, located in the Negev desert, consists of a modular array of closed photobioreactors with more than 500 km of glass tubing. The mechanism of how lutein affects cognitive functions is still not very clear. Figure 13.5. Strain selection is, therefore, an important factor in the development of a commercial process for this alga. A high amount of astaxanthin is present in its resting cells, which are produced and rapidly accumulated when the environmental conditions become unfavorable for normal cell growth (Boussiba et al., 1999; Boussiba, 2000). is another microalga very rich in astaxanthin and carotenoids. Then, at maximum cell density, the culture is pushed towards a ‘red’ stage – aplanospores – by exposure to high irradiance in open systems under nutrient stress in order to induce astaxanthin synthesis (up to 5% of dry weight) within 3–5 days.
