Carotenoid biosynthesis in Rhodotorula glutinis.
It was determined that lycopene could be cyclized directly by Rhodotorula glutinis. It was also shown the the temperature effect (i.e., increased beta-carotene synthesis in response to lower incubation temperatures) in R. glutinis was controlled by changes in enzyme concentration.
متن کاملRegulation of phenylalanine biosynthesis in Rhodotorula glutinis.
The phenylalanine biosynthetic pathway in the yeast Rhodotorula glutinis was examined, and the following results were obtained. (i) 3-Deoxy-D-arabinoheptulosonate-7-phosphate (DAHP) synthase in crude extracts was partially inhibited by tyrosine, tryptophan, or phenylalanine. In the presence of all three aromatic amino acids an additive pattern of enzyme inhibition was observed, suggesting the e...
متن کاملUtilization of date syrup as a substrate for carotenoid production by Rhodotorula glutinis
The potential use of date syrup, for the production of carotenoids by Rhodotorula glutinisin batch fermentation process, was investigated during 7 days. The results revealed that carbon (glucose or date syrup) and nitrogen sources [yeast extract, (NH4)2SO4 and NH4NO3] had a significant influence on biomass and carotenoid production. Maximum yield of total carotenoid production (7.94 mg/L) with ...

متن کاملThirteen-week oral toxicity study of carotenoid pigment from Rhodotorula glutinis DFR-PDY in rats.
Carotenoids from some of the coloured yeasts like Rhodotorula, Phaffia rhodozyma have attracted commercial interest as a natural pigment for foods. Red yeast isolated from contaminated Potato dextrose agar plate (PDA), designated as Rhodotorula glutinis DFR-PDY has been found to produce carotenoids. In the present study toxicological evaluation of carotenoid pigment has been reported. Experimen...
