Abstract
|
|
|
A potent intracellular-lipid-producing yeast, Rhodotorular glutinis var. glutinis sw-17 was studied on the production. of carotenoids after shaking the cultures for 8 days at 25℃.
The pigments were extracted with solvents and chromatographed with columns for its isolation. The carotonoids were identified by their positions on the column, and by their light-absorption curves. Close agreement was obtained between the absorption maxima of the isolated pigments and published literature values. The characteristic wave length maxima and the extinction values used for quantitative determination.
The caroteniod pigments produced by the yeast were composed of torularhodin(28.52%). torulene(38.16%), neurosporene(1.49%), γ-carotene(9.88%), β-zeacarotene(2.0%), β-carotene(19.95%) and δ-carotene(trace).
