Carotenoids production: microorganisms as source of natural dyes Produção de carotenoides: microrganismos como fonte de pigmentos naturais

open access: yesQuímica Nova, 2009
Carotenoids are natural dyes synthesized by plants, algae and microorganisms. Application in many sectors can be found, as food dyeing and supplementation, pharmaceuticals, cosmetics and animal feed.

Photoinduced Carotenogenesis in Chlorotic Euglena gracilis [PDF]

open access: yesPlant Physiology, 1970
Light induces beta-carotene synthesis in streptomycin-bleached Euglena gracilis Z. Light-adapted, chemostat-grown cells have up to 10-fold as much beta-carotene and 25% more protein than similarly grown, dark-adapted cells. Carotenogenesis does not occur under anaerobic conditions or in the presence of diphenylamine, cyanide, or cycloheximide. The blue

Accumulation of Astaxanthin by a New Haematococcus pluvialis Strain BM1 from the White Sea Coastal Rocks (Russia)

open access: yesMarine Drugs, 2014
We report on a novel arctic strain BM1 of a carotenogenic chlorophyte from a coastal habitat with harsh environmental conditions (wide variations in solar irradiance, temperature, salinity and nutrient availability) identified as Haematococcus pluvialis ...

The oleaginous astaxanthin-producing alga Chromochloris zofingiensis: potential from production to an emerging model for studying lipid metabolism and carotenogenesis

open access: yesBiotechnology for Biofuels, 2021
The algal lipids-based biodiesel, albeit having advantages over plant oils, still remains high in the production cost. Co-production of value-added products with lipids has the potential to add benefits and is thus believed to be a promising strategy to ...

Flow cytometric analysis of the encystment process induced by paraquat exposure in Haematococcus pluvialis (Chlorophyceae) [PDF]

open access: yes, 2011
The freshwater microalga Haematococcus pluvialis exhibits a unique morphological response to environmental stress, accumulating carotenoid pigment during encystment.

Detection and Enhancement of Ketocarotenoid Accumulation in the Newly Isolated Sarcinoid Green Microalga Chlorosarcinopsis PY02 [PDF]

open access: yes, 2018
The sarcinoid alga PY02 is a newly isolated soil alga native to western Thailand. In this study PY02 is described, the carotenoid profile of the green and red forms of the algal cells are compared, and the effect of nitrogen reduction and media volume on

Regulation of carotenogenesis in the red yeast Xanthophyllomyces dendrorhous: the role of the transcriptional co-repressor complex Cyc8–Tup1 involved in catabolic repression [PDF]

open access: yes, 2016
Background: The yeast Xanthophyllomyces dendrorhous produces carotenoids of commercial interest, including astaxanthin and β-carotene. Although carotenogenesis in this yeast and the expression profiles of the genes controlling this pathway are known, the

A carotenogenic mini-pathway introduced into white corn does not affect development or agronomic performance [PDF]

open access: yes, 2016
High-carotenoid corn (Carolight®) has been developed as a vehicle to deliver pro-vitamin A in the diet and thus address vitamin A deficiency in at-risk populations in developing countries.
