Role and distribution of astaxanthin in spiny lobster, Jasus lalandii
The occurance and distribution of astaxanthin in tissues of the spiny lobster, Jasus lalandii was investigated. The concentration of astaxanthin was quantified in the exoskeleton, haemolymph, muscles, gonads and hepatopancreas as well as in egg parcels from berried females during the moult as well …

Astaxanthin Decreases Invasion and MMP Activity in Triple Negative Breast Cancer Cells
Astaxanthin is a non-vitamin A carotenoid that has gained wide acceptance as a dietary supplement. We investigated whether Astaxanthin was effective against invasion and metastasis of triple-negative breast cancer (TNBC) cells. We determined that Astaxanthin decreases invasion of 4T1 cells through …

From Cultivation to Commercialisation: The Stability, Degradation, and Interactions of Astaxanthin in Haematococcus lacustris Biomass
This thesis investigated the stability of astaxanthin in Haematococcus lacustris biomass, from cultivation through the stages of downstream processing and storage, to its eventual product formulation. Astaxanthin is a valuable xanthophyll carotenoid and is widely considered one of the most powerful …

Studies on growth, modelling and pigment production by the yeast Phaffia rhodozyma
… a potential has been identified for the pigment astaxanthin. Astaxanthin is the carotenoid responsible for the distinctive coloration of salmonids, crustaceans and certain birds. Due to the fact that animals cannot synthesize carotenoids themselves, it is necessary for these pigments to be …

Development of a photobioreactor for the cultivation of the freshwater microalga Haematococcus pluvialis
… accumulates large quantities of the carotenoid astaxanthin. Astaxanthin is commercially important as a aquaculture pigment, and as a human health supplement. Currently the majority of astaxanthin used in aquaculture is synthetic. However recent advances in algal mass culture technology and …

Investigating cultivation and biorefinery process techniques on the microalgae Porphyridium aerugineum and Chromochloris zofingiensis
… biomass concentration of 5.13g/L and 14.7mg/L astaxanthin were produced after 8 days of mixotrophic cultivation. Both values show the potential competitiveness of this strain with Haematococcus sp., the traditional source of astaxanthin and provide insight for larger industrial applications of …

Nutrition Optimizing for Cultivation of H. Pluvialis on an Industrial Scale. A Novel 1750 L Photo Bioreactor Cultivation.
Astaxanthin úr örþörungum er verðmæt söluvara, örþörungurinn H. Pluvialis er mikið notaður þar sem hann er atorkusamur framleiðandi astaxanthins. Í iðnaðarræktun örþörunga er uppsöfnun lífmassa grunnurinn að framleiðslu. Einn af þeim þáttunum sem takmarka hagkvæmni framleiðslu hefur verið uppsöfnun …

Laying-Sequence Variation in Yolk Carotenoids of Eastern Bluebirds
… Bluebirds: lutein, β-carotene, zeaxanthin, astaxanthin, and β-cryptoxanthin. As predicted, the egg mass, egg length, and egg width did not vary significantly across the clutch.</p>

Determination of biologically active substances in Black Sea algae//Определяне на биологично активни вещества в черноморски водорасли
… and carotenoids (?-tocopherol, ?-carotene and astaxanthin) in the Black Sea algae selected. The final step is to perform an evaluation of the potential of the Black Sea algae as raw materials for food, pharmaceutical and cosmetic industries, showing that they are a very good source of the …

Synthesis, biological activity and mechanism of atypical carotenoid antilipoperoxidants
… Mechanistic investigation showed, as compared to astaxanthin, peridinin does not act through inhibition of lipid lateral diffusion nor does it have a higher inherent rate of radical quenching activity. SSNMR experiments with a synthesized isotopologue showed that the increased potency of peridinin …

Characterization of a Value-Added Salmon Product: Infant/toddler Food
… A preliminary investigation of the fate of astaxanthin during isothermal heating of salmon puree was also considered. The color of these products was significantly impacted by processing and inclusion of roe. Products maintained good sensory characteristics during evaluated storage period. …

Survival potential of microalgae for long-term space missions
… concentrations of antioxidants such as the red astaxanthin (keto-carotenoid) or the orange β-carotene pigments which can be utilised for human consumption. Another advantage of the physiology of these cells is that they may be more resistant to doses of radiation in space (due to the high …

Modular synthesis-enabled mechanistic characterization of the potent antilipoperoxidant activity of peridinin
… of the less effective antilipoperoxidant astaxanthin, peridinin is completely embedded within and physically spans the hydrophobic core of lipid membranes. This antilipoperoxidant probe was leveraged in human primary endothelial cell and mouse model experiments to interrogate the …
