Carotenogenesis in Haematococcus pluvialis
Nature, 1955IN a recent communication1, Goodwin and Jamikorn state that light is necessary for the synthesis of astaxanthin, the carotenoid responsible for the red colour in the alga Haematococcus pluvialis. It is not clear whether this conclusion is reached as a result of their own experience or whether they are referring to earlier information2.

Quantitative detection on metabolites of Haematococcus pluvialis by terahertz spectroscopy
Computers and Electronics in Agriculture, 2021Abstract Stressed Haematococcus Pluvialis cells would accumulate astaxanthin with the changes of lipid, pigment, and starch, which recently has been widely studied. Real-time dynamic monitoring of these components will have important guiding significance for screening high-yield and high-quality strains in the industry.

Some factors governing encystment in Haematococcus pluvialis
Archiv f�r Mikrobiologie, 1955Die Ergebnisse zeigen, das die Dauersporenbildung bei dem Flagellaten Haematococcus pluvialis in Kultur durch Storung der Vermehrung bewirkt wird, falls diese nicht eine Folge mangelnder Kohlenstoffassimilation ist. Es hat sich erwiesen, das anhaltende Assimilation fur die Bildung der Dauersporen notwendig ist, ja, das der Kohlenstoffbedarf dabei ...

Does Haematococcus pluvialis need to sleep?
Algal Research, 2019Abstract Light intensity has been identified as one of the main factors affecting the synthesis of astaxanthin in Haematococcus pluvialis, but most experiments have been carried out under unnatural continuous light, which may constitute an additional source of stress to the cells.

Biotechnological production of astaxanthin from the microalga Haematococcus pluvialis
Biotechnology Advances, 2020Although biotechnologies for astaxanthin production from Haematococcus pluvialis have been developed for decades and many production facilities have been established throughout the world, the production cost is still high. This paper is to evaluate the current production processes and production facilities, to analyze the R&D strategies for process ...

Photoreceptor electric potential in the phototaxis of the alga Haematococcus pluvialis
Nature, 1978THE nature of the primary processes in the photoreceptor and the mechanism of their coupling with the mechanical response of the flagella are the most important and, at the same time, the least investigated problems of the phototaxis in flagellates1–5.

Screening and characterization of astaxanthin-hyperproducing mutants of Haematococcus pluvialis
Biotechnology Letters, 2003Haematococcus pluvialis was mutated by UV or ethyl methanesulphonate. Mutants resistant to nicotine, diphenylamine, fluridone or norflurazon were then selected. Several nicotine-resistant mutants showed increased (1.9% to 2.5% vs. 1.2% w/w) astaxanthin production. Mutants maintained high astaxanthin production over 4 months of repeated culture.

Extensive Bioactivity of Astaxanthin from Haematococcus pluvialis in Human
2021Astaxanthin is known as a "marine carotenoid" and occurs in a wide variety of living organisms such as salmon, shrimp, crab, and red snapper. Astaxanthin antioxidant activity has been reported to be more than 100 times greater than that of vitamin E against lipid peroxidation and approximately 550 times more potent than that of vitamin E for singlet ...

Recent advances in biorefinery of astaxanthin from Haematococcus pluvialis
Bioresource Technology, 2019Haematococcus pluvialis is one of the most abundant sources of natural astaxanthin as compared to others microorganism. Therefore, it is important to understand the biorefinery of astaxanthin from H. pluvialis, starting from the cultivation stage to the downstream processing of astaxanthin.

[Advances in astaxanthin biosynthesis in Haematococcus pluvialis].
Sheng wu gong cheng xue bao = Chinese journal of biotechnology, 2019Astaxanthin is widely applied as a nutraceutical, pharmaceutical, and aquaculture feed additive because of its high antioxidant activity. Haematococcus pluvialis is a microalgal species that can largely accumulate astaxanthin under adverse environmental conditions. Here we review the research progress of astaxanthin biosynthesis in H.
