Biomass and lipid production with Microchloropsis salina in open thin-layer cascade photobioreactors

Torben Schädler, doctoral thesis Technical University of Munich, 2021

Nutrient- and water recycling, optimized CO₂ fixation and reduction of hydraulic power input allow the efficient production of Microchloropsis salina in open thin-layer cascade photobioreactors in batch or continuous mode. At a physically simulated Mediterranean summer climate, lipid concentration and productivity were increased by one magnitude compared to literature data. A continuous two-step process applying two serially connected photobioreactors was subsequently transferred to the 50 m² scale.
