Abstract Among the highly valued ketocarotenoids employed for food coloration, astaxanthin is probably the most important. This carotenoid may be produced biotechnologically by a number of microorganisms, and the most promising seems to be the freshwater flagellate Haematococcus pluvialis (Chlorophyceae), which accumulate astaxanthin in their aplanospores. Many physiological aspects of the transition of the flagellate into aplanospores have been described. Mixotrophic cultivation and suitable… Expand
Microalgas, produtos e aplicações
TLDR
In recent years, much interest has been focused on the biotechnological potential of microalgae, mainly due to the identification of several substances synthesized by these organisms, which can be especially used in the development of functional food, for its nutritional and pharmaceutical properties. Expand
An economic assessment of astaxanthin production by large scale cultivation of Haematococcus pluvialis.
TLDR
Based on the analysis, the production cost of astaxanthin and microalgae biomass can be as low as $718/kg and $18/kg respectively, which is very encouraging because the estimated cost might be lower than that of chemically synthesized astaxantha. Expand
Biotechnological production of astaxanthin with Phaffia rhodozyma/Xanthophyllomyces dendrorhous
TLDR
This review emphasizes the potential of P. rhodozyma for the biotechnological production of astaxanthin in comparison to other natural sources such as the microalga H. pluvialis, other fungi and transgenic plants and to chemical synthesis. Expand
Secondary ketocarotenoid astaxanthin biosynthesis in algae: a multifunctional response to stress
TLDR
In this contribution, the various biochemical, genetic, and molecular data related to the biosynthesis of ketocarotenoids by Haematococcus pluvialis and other taxa are reviewed and compared and a tentative regulatory model of the biochemical network driving astaxanthin production is proposed. Expand
Astaxanthin Accumulation in the Green Alga Haematococcus pluvialis: Effects of Cultivation Parameters
TLDR
Results show that stresses applied in culture, which interfere with cell division, trigger the accumulation of astaxanthin and Notably, sulfur starvation results in a massive accumulation of this commercially important carotenoid. Expand
Stimulated Growth of Green Algae Haematococcus Pluvialis Under Different Environmental Conditions
Abstract Haematococcus pluvialis is a genus of green algae that keeps the high interest of the scientists for decades due to its capacity to synthesize astaxanthin. Among many others, astaxanthin isExpand
Molecular and biochemical studies of astaxanthin biosynthesis in Haematococcus pluvialis
TLDR
expression of carotenoid biosynthetic genes revealed that they are up-regulated and maximum transcript levels of phytoene synthase, lycopene cyclase, and -carotene ketolase genes were found to be higher than that in green vegetative cells under stress conditions, which suggested a possible involvement of acetate in the posttranscriptional modifications of carOTenoid genes.

Attached cultivation of Haematococcus pluvialis for astaxanthin production.
Haematococcus pluvialis, the best natural source for astaxanthin, was cultivated with an immobilized biofilm method, viz. "attached cultivation", which was high in photosynthetic efficiency. AExpand
Astaxanthin Production from Microalgae
Astaxanthin is commercially sold as a pigment for animal feed and as an antioxidant for the nutraceutical sector. Astaxanthin is predominantly manufactured synthetically from petrochemicals but isExpand
Producing Natural Mixed Carotenoids from Dunaliella salina
TLDR
The aim of this work was to cultivate the micro algae Dunaliella salina isolated from the Dead Sea by using a certain media, and it is evident that this process should find its way for commercialization through a pilot plant at the first step, then by an industrial plant after verifying the results of the pilot plant.

Astaxanthin production by a green alga, Haematococcus pluvialis accompanied with morphological changes in acetate media
TLDR
Two acetate containing media were developed for astaxanthin production by a green unicellular alga, Haematococcus pluvialis and pyruvate was an especially good carbon source both for the algal cell growth and the carotenoid synthesis. Expand
Inhibition of astaxanthin synthesis in the green alga, Haematococcus pluvialis
TLDR
Selective use of inhibitors of carotenogenesis demonstrated that the accumulated lycopene and β-carotene could act as a precursor for astaxanthin synthesis. Expand
Autotrophic growth and carotenoid production of Haematococcus pluvialis in a 30 liter air-lift photobioreactor
TLDR
Growth and ketocarotenoid (astaxanthin) production by the fresh-water green unicellular alga Haematococcus pluvialis has been evaluated in a 30 l air-lift photobioreactor and the use of a batch-production process in a air- Lift reactor for the synthesis of algal carotenoids is discussed. Expand
Astaxanthin Accumulation in the Green Alga Haematococcus pluvialis1
TLDR
Cells of the green microalga Haematococcus pluvialis were induced to accumulate the ketocarotenoid pigment, astaxanthin by the application of the following environmental conditions: light intensity, phosphate starvation and salt stress, which retarded cell growth as reflected by a decrease in cell division rate, but led to an increase in astaxantha content per cell.
