Carotenoids: Carotenoid and apocarotenoid analysis—Use of E. coli to produce carotenoid standards

2022
Authentic samples of many carotenoids are commercially available, but are often too expensive and of insufficient purity. As an alternative, a wide range of carotenoids can be biosynthesized in recombinant Escherichia coli strains. E. coli cells naturally produce the carotenoid biosynthetic precursors and provide a blank slate for manufacturing ...

Photoprotection by carotenoids

Journal of Ethnopharmacology, 1988
Carotenoid pigments have been found to have a protective function against photosensitization in green plants. This protective ability has been exploited in the administration of high doses of beta-carotene to patients with erythropoietic protoporphyria to ameliorate the photosensitivity associated with this disease.

Microbial Carotenoids

2012
Carotenoids are among the most widely distributed pigments in nature, and they are exclusively synthesized by plants and microorganisms. These compounds may serve a protective role against many chronic diseases such as cancers, age-related macular degeneration, and cardiovascular diseases and also act as an excellent antioxidant system within cells ...

Carotenoids and Photosynthesis

2016
Carotenoids are ubiquitous and essential pigments in photosynthesis. They absorb in the blue-green region of the solar spectrum and transfer the absorbed energy to (bacterio-)chlorophylls, and so expand the wavelength range of light that is able to drive photosynthesis.

Carotenoids in Microalgae

2016
Carotenoids are a class of isoprenoids synthesized by all photosynthetic organisms as well as by some non-photosynthetic bacteria and fungi with broad applications in food, feed and cosmetics, and also in the nutraceutical and pharmaceutical industries.

Biotransformation of carotenoids to retinal by carotenoid 15,15′-oxygenase

Applied Microbiology and Biotechnology, 2010
Retinal, a precursor of vitamin A, has been used in foods, cosmetics, pharmaceuticals, nutraceuticals, and animal feed additives. Carotenoid 15,15'-oxygenases, including β-carotene 15,15'-oxygenases from mammalians, chickens, fruit flies, zebrafishes, the uncultured marine bacterium, and the fungus Fusarium fujikuroi, and apo-carotenoid 15,15 ...

The carotenoids of Rhodopseudomonas. I. Carotenoids of the green mutant

Archives of Biochemistry and Biophysics, 1958
Abstract The two main carotenoid pigments of a green mutant of Rhodopseudomonas spheroides are neurosporene, a tetrahydrolycopene, C 40 H 60 ; and chloroxanthin, C 40 H 60 O 2 . The latter contains at least one and possibly two hydroxyl groups. Because they are difficult to acetylate, it is suggested they may be tertiary alcohols.

The Carotenoids of Several Low‐Carotenoid Fruits

Journal of Food Science, 1964
SUMMARY The carotenoids were examined in several fruits of low carotenoid content. Fruits studied in detail were black figs, cranberries, and Thompson seedless grapes; the examination was less comprehensive for blackberries, blueberries, strawberries, and pomegranates.
