dc.descriptionMixing displays a major role in the growth of photosynthesis microorganisms in active suspensions: it gives access to nutrients, improves the microorganisms’ exposure to light, and homogenizes temperature distribution in photobioreactors (PBRs). Therefore, mixing is an essential factor in the design and optimization of PBRs for biomass culture. However, different mixing modes can affect cell growth differently. In this study, three different modes of mixing, ranging from turbulent stirring, as the upper bound of mixing, orbitally shaken flow, as the lower bound of mixing, and simple molecular diffusion, were applied for cultivations of the cyanobacterium Synechocystis sp. CPCC 534. Results showed that imposing mixing on the culture can improve the growth rate as well as biomass yield production compared to simple molecular diffusion. The diffusion model shows the lowest growth rate and the lowest yield production in this study. Part of Proceedings of the Canadian Society for Mechanical Engineering International Congress 2022.
