“…The volumetric biomass productivities of both batch processes remain unchanged within the estimation error (0.77±0.02 g CDW L ‐1 d −1 with “BG11+” and 0.79±0.02 g CDW L ‐1 d −1 with “BG11 Biomass” medium) indicating light limitation. It must be pointed out that these biomass space‐time yields represent a more than 50‐fold increase compared to 15 mg CDW L ‐1 d −1 so far reported with D. salina produced in a flat‐plate photobioreactor at photoautotrophic conditions [32]. Applying D. salina in a tubular photobioreactor with a CO 2 supply and 12 h cycles of light and dark [34] resulted in the highest biomass space‐time yield so far reported (0.54 g CDW L ‐1 d ‐1 ), which is 31 % lower than our results.…”

“…So far, growth and carotenoid production with D. salina was studied on a laboratory scale keeping all state variables constant, e.g. light intensity, temperature and salinity [32–36]. However, outdoor conditions are subject to day and night cycles of incident light and temperature.…”

Batch growth and β‐carotene production of Dunaliella salina CCAP19/18 was investigated in flat‐plate gas‐lift photobioreactors with a light path of 2 cm, operated in physically simulated outdoor conditions. Dunaliella salina CCAP19/18 showed robust growth with respect to pH 8.0‐9.0 and 15–35°C at increasing salinity, simulating the evaporation of open photobioreactors. The highest β‐carotene concentration of 25 mg L‐1 (3 mg gCDW−1) was observed in batch processes at pH 8.5, 15–30°C and increasing salinity up to 110 g L‐1, simulating a typical Mediterranean summer climate. Intracellular β‐carotene accumulation of D. salina CCAP19/18 was shown to be independent of light availability, although nutrient limitation (K2HPO4, MgSO4, and/or ammonium ferric citrate) seems to enable stable β‐carotene content in the algal cells despite increasing cell densities in the photobioreactor. Fully controlled, lab‐scale photobioreactors simulating typical climate conditions of any region of interest are valuable tools for enabling a realistic characterization of microalgae on a laboratory scale, for production processes projected in open photobioreactor systems (e.g. thin‐layer cascade photobioreactors).

“…β‐carotene is a natural pigment founded in a greater proportion in the microalgae Dunaliella salina and contains two isomers; all‐trans‐β‐carotene and 9‐cis‐β‐carotene, which are attributed to various antioxidant properties such as anticancer treatment, prevention of tissue aging, efficiency of the immune system, UV‐B sun protection, among others (García, Manzano, Moreno, & Guerrero, 2000; Hemaiswarya & Doble, 2006; Jayappriyan, Rajkkumar, Venkatakrishnan, Nagaraj, & Rengasamy, 2013; Khadim et al, 2018; López, Olivarría, Medina, Miranda, & Martinez, 2013; Meléndez, Vicario, & Heredia, 2004).…”

Chlorophyte microalgae Dunaliella are halophilic flagellated cells; they can resist high salinities, producing β-carotene to balance osmotic stress. This pigment has important antioxidant properties for biotechnology, the prevention of tissue aging, the efficiency of the immune system, and sun protection against UV-B rays. The objective of this study was to characterize native strains of the genus Dunaliella from the Marine Institute of Peru, under the influence of stress factors for the production and concentration of β-carotene. Different tools were used to characterize these strains through molecular analysis, optimization of parameters for carotene accumulation, growth curves, life cycle, and carotene analysis. The accumulation of this pigment was mainly due to adaptation to salt stress. The differences between Dunaliella strains according to their population growth demonstrated that they did not have the same capacity to respond to the same cultivation conditions, although most of them are from the same species. The IMP-BG-001 strain, from Piura, can accumulate high concentrations of β-carotene
