A numerical framework to predict the performances of a tubular photobioreactor from operating and sunlight conditions
2021, Algal ResearchCitation Excerpt :The latter is previously quantified by a light attenuation model either Beer-Lambert law or a two-flow model [19] which considers absorption without and with diffusion by microalgae respectively. Indeed, none of these simulations include the dynamic response of the cells to the light actually seen as they move along the light gradient, which allows to account for the effect of light/dark cycles called “flashing light” [20–22]. This effect, which is driven by the combination of mixing (large eddy scale and local turbulence) and spatial light heterogeneity, depends on bioreactor geometry.
Photosynthetic electron transport transients in Chlorella vulgaris under fluctuating light
2019, Algal ResearchCitation Excerpt :Finally, if the light energy capture outruns protective processes, then PSII photochemical damage can in turn outrun counteracting repair processes, leading to net photoinhibition. Nevertheless, in many taxa, rapid turnover of PSII protein subunits mediates PSII repair after photoinactivation [20,21]. Chlorophyll fluorescence is an information rich, rapid and non-invasive approach to monitoring photosynthetic performance and acclimation state.

2017, Algal ResearchCitation Excerpt :At high irradiance, algae must migrate between light saturated regions and darker regions to avoid photoinhibition and light limitation, respectively, to increase photosynthetic efficiency. This mechanism has also been engineered into systems as “temporal light dilution”, “the flashing light effect”, or “light-dark frequency”, using mixing to reduce light deficiency and photoinhibition [20–22]. Overall, at large-scales, spatial light dilution ultimately occupies land surface area [23], increasing capital costs, while simultaneously compromising areal productivity.
