Directed cultivation of Chlorella sorokiniana to increase carotenoid synthesis

Бесплатный доступ

Chlorella sorokiniana is a promising species for cultivation both in the laboratory cultivator and on an industrial scale. Its biomass is the source of many valuable components, including plastid pigments, which have high antioxidant activity. The metabolism of Chlorella sorokiniana is subject to change under the influence of various cultivation conditions. With dosed ultraviolet radiation, a compensatory increase in the synthesis of carotenoids is possible, which prevents oxidative stress. The cultivation of C. sorokiniana (strain 211-8k) was carried out in various conditions of illumination: the control version - illumination with a fluorescent lamp; option 1 - dosed periodic ultraviolet exposure every day for 15 min (spectral region of the light flux 280-315 nm (UV-B), intensity 1300 Lux) and further illumination with a fluorescent light; option 2 - ultraviolet irradiation for 30 min (spectral region of the light flux 280-315 nm (UV-B), intensity 1300 Lux) in the stabilization phase...
