Carotenoids Functionality, Sources, and Processing by Supercritical Technology: A Review

Journal of Chemistry, Volume 2016, Issue 1, 2016., 2016
Carotenoid is a group of pigments naturally present in vegetal raw materials that have biological properties. These pigments have been used mainly in food, pharmaceutical, and cosmetic industries. Currently, the industrial production is executed through chemical synthesis, but natural alternatives of carotenoid production/attainment are in development.

Characterization of the Geranylgeranyl Diphosphate Synthase Gene in Acyrthosiphon pisum (Hemiptera: Aphididae) and Its Association With Carotenoid Biosynthesis

Frontiers in Physiology, 2019
Carotenoids play many crucial roles in organisms. Recently, the de novo synthesis of carotenoids has been reported in pea aphid (Acyrthosiphon pisum) through horizontally transferred genes.

Colorful World of Microbes: Carotenoids and Their Applications

Advances in Biology, Volume 2014, Issue 1, 2014., 2014
Microbial cells accumulate pigments under certain culture conditions, which have very important industrial applications. Microorganisms can serve as sources of carotenoids, the most widespread group of naturally occurring pigments. More than 750 structurally different yellow, orange, and red colored molecules are found in both eukaryotes and ...

Sustainable Recovery of Carotenoids From Rhodotorula glutinis: A Comparison Between Ultrasound‐ and Microwave‐Assisted Extraction Mechanisms

Journal of Food Processing and Preservation, Volume 2026, Issue 1, 2026.
This work is aimed at evaluating the sustainable extraction of carotenoids from the yeast Rhodotorula glutinis, comparing the effect of ultrasound‐assisted extraction (UAE) and microwave‐assisted extraction (MAE), respectively. The extraction process was optimized using a 22 central composite rotatable design (CCRD).
