The analysis of fucoxanthin (FCX) in algal biomasses presents some limitations, especially regarding the sample preservation after collection until extraction pigment. FCX stability was evaluated biomass samples one diatom and three brown seaweed species (Phaeophyceae) their extracts stored at -20ºC -80ºC, for 60 days. Fucoxanthin quantified through UHPLC-DAD. methanolic micro/macroalga -80ºC w...

Brown algae and its carotenoids have been shown to have a positive influence on obesity and its comorbidities. This study evaluated the effect of Undaria pinnatifida and fucoxanthin on biochemical, physiological and inflammation markers related to obesity and on the expression of genes engaged on white adipose tissue lipid metabolism in a murine model of diet-induced obesity. The treatments imp...

Survival of osteosarcoma patients hinges on prevention or treatment of recurrent and metastatic lesions. Therefore, novel chemotherapeutics for more effective treatment and prevention of this disease are required. Carotenoids are natural pigments and exhibit various biological functions. We evaluated the anti-osteosarcoma properties of several carotenoids. Among carotenoids, fucoxanthin and its...

The marine ecosystem is considered a potentially mysterious reservoir of biodiversity consisting broad spectrum bioactive constituents, whose potential still under research for pharmaceuticals, nutraceuticals and cosmeceuticals. Fucoxanthin, carotenoid, can be found in the brown seaweeds recognized to show promising exclusive biological activities. Subsequent consumption absorption fucoxanthin ...

The superfamily of light-harvesting complex (LHC) proteins is comprised of proteins with diverse functions in light-harvesting and photoprotection. LHC proteins bind chlorophyll (Chl) and carotenoids and include a family of LHCs that bind Chl a and c. Dinophytes (dinoflagellates) are predominantly Chl c binding algal taxa, bind peridinin or fucoxanthin as the primary carotenoid, and can possess...

In recent decades, the worldwide production of microalgae has been carried out on an industrial scale. years, market for natural products grown because changes in consumer preferences more products. The objective this study was to demonstrate hepatoprotective capacity fucoxanthin extract obtained from culture Phaeodactylum tricornutum (Culture Collection Alga and Protists Scotland). microalga a...

The brown alga Saccharina japonica is widely consumed in Asian countries, and post-harvest drying methods such as sun oven are commonly used to extend the shelf life of S. japonica. Thus, present study analyzed ethanol extract organic solvent fractions examine effects UVA heating on certain bioactive compounds (fucoxanthin, phlorotannin compounds, total antioxidants) during process. fucoxanthin...

It is known that microalgae respond to different light colors, but not at single-cell level. This work aimed assess if colors could be used as triggers sort over-producing cells. Six spectra were used: red + green blue (RGBL), (BL), (RL), (GL), (BRL) and (BGL). Fluorescence-activated cell sorting method was analyse fluorescence BGL RGBL lead the highest fucoxanthin production, while RL showed l...
