This paper presents a parametric study simulating light transfer in a photobioreactor containing gas bubbles and filamentous cyanobacteria Anabaena variabilis suspended in water. To the best of our knowledge, this paper presents for the first time a model for such system: (i) using a consistent set of radiation characteristics of the medium derived from experimental data and from Mie theory; (i...

A versatile LED based miniature photobioreactor ideal for factorial experiments that allows simultaneous testing of a wide range variables and experimental combinations needed high-throughput screening analysis.

From the cell to photobioreactor and industrial exploitation of microalgae, through controlled experiments modelling.

From an engineering point of view, the effect of light intensity distribution on the stability of growth rate should be taken into account in designing effective photobioreactors and sustaining stable growth rates. In the experiments described here, in order to keep operational parameters at an almost constant level, a semi-continuous culture method was developed for cultivation of photosynthet...

It has been suggested that the energy-efficient production of microalgae biomass can be more easily obtained in short light path photobioreactors operated at high concentration. On downside, however, concentrations also require an efficient gas exchange rate to avoid metabolic growth limitation or inhibition. A cascade photobioreactor featuring a thin liquid layer flowing down sloping, wavy-bot...

A novel approach to cultivating cyanobacteria is presented which utilizes near-field evanescent waves on the surface of waveguides to excite the photocenters in the thylakoid membranes of cyanobacteria. This approach to light delivery when applied to photobioreactor design may provide an opportunity to significantly increase yield and make biofuels an economically competitive alternative to tra...
