Carotenoid Distribution in Living Cells of Haematococcus pluvialis (Chlorophyceae)
Haematococcus pluvialis is a freshwater unicellular green microalga belonging to the class Chlorophyceae and is of commercial interest for its ability to accumulate massive amounts of the red ketocarotenoid astaxanthin (3,3'-dihydroxy-β,β-carotene-4,4'-dione). Using confocal Raman microscopy and multivariate analysis, we demonstrate the ability to spectrally resolve resonance-enhanced Raman sig...
متن کاملCharacterization of carotenoid hydroxylase gene promoter in Haematococcus pluvialis.
Astaxanthin, a high-value ketocarotenoid is mainly used in fish aquaculture. It also has potential in human health due to its higher antioxidant capacity than beta-carotene and vitamin E. The unicellular green alga Haematococcus pluvialis is known to accumulate astaxanthin in response to environmental stresses, such as high light intensity and salt stress. Carotenoid hydroxylase plays a key rol...
متن کاملImage-based monitoring system for green algal Haematococcus pluvialis (Chlorophyceae) cells during culture.
The green microalga Haematococcus pluvialis accumulates the red pigment astaxanthin accompanied by morphological changes under stress conditions, including nutrient depletion, continuous light and high temperature. To investigate the physiological state of the algal cells, we developed the digital image-processing software called HaematoCalMorph. The software automatically outputs 25 single-cel...
متن کاملSources of inorganic fertilizer in the growth of Haematococcus pluvialis Flotow (Chlorophyceae)
The influence of inorganic fertilizer media at different concentrations on the growth and biochemical composition of Haematococcus pluvialis microalgae was evaluated. Microalgae were placed in a bath culture with inorganic fertilizer (NPK) medium and WC medium during 28 days, Growth and biological aspects of microalgae between the media were compared. Mineral concentrations affected the physiol...
متن کاملFunctional Characterization of a Missing Branch Component in Haematococcus pluvialis for Control of Algal Carotenoid Biosynthesis
Cyclization of acyclic lycopene by cyclases marks an important regulatory point in carotenoid biosynthesis. Though some algal lycopene epsilon cyclases (LCYEs) have been predicted computationally, very few have been functionally identified. Little is known about the regulation mechanisms of algal LCYEs. Recent comparative genomic analysis suggested that Haematococcus pluvialis contained only th...
