Improvement of carotenoid-synthesizing yeast Rhodotorula rubra by chemical mutagenesis.
A mutant Rhodotorula rubra with enhanced carotenoid-synthesizing activity for synthesizing total carotenoids and beta-carotene was obtained by N-methyl-N'-nitro-N-nitrosoguanidine mutagenesis. When co-cultivated with yogurt starter bacteria (Lactobacillus bulgaricus + Streptococcus thermophilus) in whey ultrafiltrate it produced 15.7 mg total carotenoids l(-1) culture fluid or 946 microg total ...
متن کاملProduction of Carotenoid-/Ergosterol-Supplemented Biomass by Red Yeast Rhodotorula glutinis Grown Under External Stress
The aim of this study is to compare the production of biomass enriched with carotenoids and ergosterol by yeast strain Rhodotorula glutinis CCY 20-2-26 grown under optimal growth conditions and in the presence of exogenous stress factors. R. glutinis cells were exposed to UV irradiation, oxidative stress (2–10 mmol/L H2O2) and osmotic stress (2–10 % NaCl). During the experiment, growth characte...
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 کاملImproving carotenoid pigments production in Rhodotorula mucilaginosa using UV irradiation
Rhodotorula yeasts were isolated from various local sources in Damascus, Syria, during 2012 and 2013. Fifty isolates (23 from leaves trees, 13 from different soils, 6 from different meats, 6 from dairy products, 1 pickle and 1 traditional sweet) were identified using API 20C AUX system. Isolated yeasts were classified into three Rhodotorula species: R. mucilaginosa, R. glutinis and R. minuta re...
متن کاملCarotenoid Production by Rhodotorula sp. on Fruit Waste Extract As a Sole Carbon Source and Optimization of Key Parameters
Fruit waste extract was selected as the sole substrate for carotenoid production and the effect of parameters like pH, temperature and agitation have been studied. A two-step simple sequential strategy was employed for the optimization of carotenoid production by Rhodotorula rubra. In the first step, one factor at a time was employed to evaluate the impact of pH on carotenoid production. Th...
