Ultrasonic Treatment Enhanced Astaxanthin Production of Haematococcus pluvialis
Journal of Microbiology, 2023In this study, effects of ultrasonic treatment on Haematococcus pluvialis (H. pluvialis) were investigated. It has been confirmed that the ultrasonic stimulation acted as stress resources in the red cyst stage H. pluvialis cells containing astaxanthin, resulting in additional astaxanthin production.

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.

Metabolic response of cyanide in Haematococcus pluvialis
Journal of Plant Biochemistry and Biotechnology, 2021The green alga Haematococcus pluvialis is able to produce and accumulate large amounts of astaxanthin under stress conditions. In this study H. pluvialis was exposed to different concentrations of cyanide (0, 6, 9 and 12 µM), in two-time periods (treatmenton = 14 days and pre-treatment = 7 days) to compare the changes on growth and biochemical ...

Attached cultivation of Haematococcus pluvialis for astaxanthin production
Bioresource Technology, 2014Haematococcus pluvialis, the best natural source for astaxanthin, was cultivated with an immobilized biofilm method, viz. "attached cultivation", which was high in photosynthetic efficiency. A practical operational protocol for this "attached cultivation" method was investigated by studying the effects of inoculum density, light intensity, nitrogen ...

Semi-continuous Cultivation of Haematococcus pluvialis for Commercial Production
Applied Biochemistry and Biotechnology, 2009The objectives of the present study on the growth of Haematococcus pluvialis were to indicate the effects of a long-term semi-continuous cultivation, sterilization, carbon dioxide, and different culture media by using artesian well water. This investigation was an enterprise in order to commercialize the production economically. When the effect of CO(2)

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.

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 ...

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 ...

Gametogenesis in Haematococcus pluvialis Flotow (Volvocales, Chlorophyta)
Phycologia, 1997Abstract An effective method of inducing gametogenesis in Haematococcus pluvialis Flotow (Volvocales, Chlorophyta) is described. Cultures starved for at least one month and then supplied with fresh medium produced gametes the following day. Isolated gametocysts initiated subcultures without syngamy, suggesting parthenogenetic development.
