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 کاملTorularhodin Biosynthesis and Extraction by Yeast Cells of Rhodotorula Rubra
The paper presents the research work done to study the discontinuous bioprocess for the intracellular carotenoidic pigment torularhodin formation with the yeast Rhodotorula rubra ICCF 209. The growth and carotenoid biosynthesis of the yeast Rhodotorula rubra was studied by cultivation in 3.7 L Bioengineering AG lab bioreactor with mechanical stirring at an air flow rate of 200 L/h and agitation...
متن کاملIron Uptake and Translocation by Macrocystis pyrifera.
Parameters of iron uptake have been determined for blade tissue of Macrocystis pyrifera (L.) C. Ag. These include the effects of iron concentration, light, various inhibitors, and blade type. All experiments were conducted in the defined artificial seawater Aquil. Iron uptake is light independent, energy dependent, and dependent on the reduction from Fe(3+) to Fe(2+). Iron is concentrated in th...
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...
متن کاملfaciliting lexical access for the fluent production of speech
the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis,a one-way anova experimental design was carried out. 24 sednior students of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inter...
