The role of photoperiods on photobioreactors - A potential strategy to reduce costs.The aim of this work was evaluate the role of photoperiods (long-term, frequencies and short) on the growth and lipid content of microalgae Scenedesmus obliquus CPCC05.  Moreover, the best trade-offs between biomass productivity and light energy economy occurred in photoperiods of 0.5:0.5s and 0.91:0.09s (light:dark), and those between lipid productivity and light energy economy occurred in the frequency photoperiod of 24 and 48 t/d.  Thus, the use of the photoperiods are an effective strategy for reducing costs of microalgal biomass production.
