TL;DR: In this paper, a methodology is presented for designing photobioreactors with tubular loop solar receivers in which the fluid is circulated by an air-lifting device, which effectively combines the relevant aspects of external irradiance-dependent cell growth, oxygen accumulation in the solar loop, oxygen removal in the air-lifting device, and hydrodynamics of the airlift system that determine the flow velocity through the solar receiver.

TL;DR: A dynamic model of photosynthesis is developed, accounting for factors such as photoadaptation, photoinhibition, and the "flashing light effect," and is shown to explain the reported photosynthesis-irradiance responses observed under various conditions.

TL;DR: The bottlenecks for the scale-up of the different technologies and thus of microalgae production are summarized and the obligation of adequate control strategies is discussed.

TL;DR: A mathematical model for light-limited growth of a continuous microalgal culture is proposed, which reproduced the steady states reached and the dynamic behavior of the system when the dilution rate was changed.

TL;DR: A mathematical model to estimate the solar irradiance profile and average light intensity inside a tubular photobioreactor under outdoor conditions is proposed, requiring only geographic, geometric, and solar position parameters.
