Abstract: In order for the use of biological carotenoids to become feasible, it is necessary to have adequate low cost sources and improved methods of cultivation. The aim of this study was to evaluate the effect of supplementation with nitrogen, phosphorus, zinc, and magnesium, on the biomass and carotenoid volumetric production by yeast Rhodotorula rubra L02 using a complex medium (sugarcane juice) and synthetic media (sucrose and maltose) as substrates. The experimental design used for each substrate was randomized i… Show more

“…Anthocyanins and carotenoids are color pigments that are randomly circulated in different sugarcane species. 23,28 The end product of the flavonoid biosynthesis pathway is anthocyanin. 40 The DFR gene encodes a key enzyme, named "dihydroflavonol-4-reductase", which causes the reduction of dihydroflavonols to leucoanthocyanidins in the proanthocyanidin and anthocyanin biosynthesis pathway.…”

“…Phenolic compounds are widely distributed in living organisms having diverse roles in plant species. Among different phenolic compounds, flavonoids are prominent because they are biologically active in nature and have powerful antioxidant activities that protect plants against various abiotic and biotic stresses. , To date, few studies have found that the juice, leaves, and peels of S. officinarum contain flavonoid compounds whereas no detailed metabolic study has been conducted in other cultivated sugarcane species. ,,, Flavonoids and anthocyanins are used as synthetic additives and synthetic dyes, and the consumption of dietary flavonoids decreases the risk of cardio- and cerebrovascular diseases, cancer, diabetes, failing vision, and atherosclerosis. ,, Moreover, flavonoids have powerful antioxidant properties that protect the cellular organelles from oxidative damage and also protect from greater light stress. , Additionally, carotenoids (red, orange, and yellow organic pigments) and proanthocyanidins (key precursors of the red and blue-violet pigments) are also considered robust antioxidants that play a significant role in the protection of plant cells during oxidative stress. ,,, …”
