Electron. j. biotechnol; 51 (), 2021
BACKGROUND: Scavenger receptor class B (SRB) is a multifunctional protein in animals that participates in physiological processes, including recognition of a wide range of ligands. Astaxanthin is a major carotenoid found in shrimp. However, the molecular mechanism of astaxanthin and SRB protein binding h...

Hydrolytic efficiency and isomerization during de-esterification of natural astaxanthin esters by saponification and enzymolysis

Su, Fang; Xu, Huarong; Yang, Na; Liu, Wei; Liu, Jianguo.
Electron. j. biotechnol; 34 (), 2018
Background: Astaxanthin from natural sources is typically esterified with fatty acids; hence, it must be hydrolyzed to remove esters before identification and quantification by conventional HPLC. Alkaline-catalyzed saponification and enzyme-catalyzed enzymolysis are the most commonly used de-esterificati...

Un método basado en la PCR para la identificación rápida de levaduras acumuladoras de astaxantina (Phaffia spp. )
PCR-based method for the rapid identification of astaxanthin-accumulating yeasts (Phaffia spp.)

Colabella, Fernando; Libkind, Diego.
Rev. argent. microbiol; 48 (1), 2016
It has been recently found that the natural distribution, habitat, and genetic diversity of astaxanthin-producing yeasts (i.e. Phaffia rhodozyma, synonym Xanthophyllomyces dendrorhous) is much greater than previously thought. P. rhodozyma is biotechnologically exploited due to its ability to produce the ...

Study on the relationship between intracellular metabolites and astaxanthin accumulation during Phaffia rhodozyma fermentation

Xiao, Anfeng; Jiang, Xinglong; Ni, Hui; Yang, Qiuming; Cai, Huinong.
Electron. j. biotechnol; 18 (3), 2015
Background To study the relationship between intracellular anabolism and astaxanthin production, the influence of intracellular protein and fatty acids on astaxanthin production by four mutant Phaffia rhodozyma strains and their variations was investigated in this research. Results First, the content of ...
