title: Production of β‐carotene with <i>Dunaliella salina</i> CCAP19/18 at physically simulated outdoor conditions
abstract: Batch growth and β-carotene production of <i>Dunaliella salina</i> CCAP19/18 was investigated in flat-plate gas-lift photobioreactors with a light path of 2 cm, operated in physically simulated outdoor conditions. <i>Dunaliella salina</i> 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<sup>-1</sup> (3 mg g<sub>CDW</sub> <sup>-1</sup>) was observed in
