A new type of preparative photobioreactor for high quality production of microalgae is developed for hatchery-nursery of marine animals, as well as for fine chemicals extraction. Of modular conception, two artificial light photobioreactors in plastic and stainless steel are designed so as to provide strictly controlled conditions in an attempt to increase quality and diminish cost prices. They are assessed for production of Porphyridum cruentum and compared to conventional transparent tanks and solar photobioreactors. The concentration and productivity obtained are ten-fold higher than with hatchery tanks, which leads to a significant drop in cost price of biomass. Comparison is also made with a 10 m2 solar photobioreactor operated in the south of France, for which biomass cost price is half that of 1.5 m2 artificial light photobioreactor. Extrapolations erasing size discrepancy show that the cost price of the two technologies are not very different. [ABSTRACT FROM AUTHOR] |
