Abstrakt:

The influence of UVA and VIS radiation on the β-carotene biosynthesis by yeast Rhodotorula mucilaginosa was studied. The impact of radiation characteristic on biomass growth, substrate consumption and β-carotene production in submerged batch culture in bioreactor was studied. Three different types of light sources were used in the experiment: VIS – 15 W, wavelength range from 400 to 800 nm, the largest emission at 420 nm; UVA – 18 W, blue light, wavelength range of 350 to 430 nm, the largest emission at 370 nm; UVA – 20 W, wavelength range from 350 to 575 nm, the largest emission at 350 nm. In cultures conducted with UVA – 18 W radiation the highest β-carotene and carotenoids cellular concentration were achieved, respectively 63.20 μg/gd.w. and 0.97 mg/gd.w.. In cultures subject to VIS radiation a lower β-carotene concentration at 43.60 μg/gd.w. and the total carotenoids concentration at 0.83 mg/gd.w. was obtained. The ultraviolet radiation with the emission peak of radiation at 370 nm promoted the β-carotene and carotenoids production in yeast Rhodotorula mucilaginosa
