Carotenes and xanthophylls in mycobacteria. III. Influence of light on the pigment synthesis of chromogenic bacteriaThe influence of light on pigment synthesis of growing photo- and scotochromogenic mycobacteria was investigated. Optimal incubation time, duration of light-exposure, influence of the ...

Variation in carotenoid content of corn and of gluten fractions creates problems in blending mixed feeds to guaranteed levels of xanthophylls and carotenes. Samples of hybrid yellow dent corn, typical of those processed by wet-millers, showed a three- to fourfold variation in xanthophylls (10-30 ...
It is a dihydroxy derivative of β-carotene and belongs to a group of pigments known as oxycarotenoids, which are part of a large group of natural colorants known as xanthophylls [2, 4, 5]. Beyond its role as a pigment, zeaxanthin is recognized for its diverse physiological properties, ...
