Abstract
In order to improve biological processes involved in biofuel production from microalgae, photobioreactors (PBR) should be adapted to control the production in optimal conditions. It should be first to study and control adapted reactors to model the entire process and facilitate the decision on the choice of raw material and design means, and finally to demonstrate the experimental feasibility of the process and allow biomass conversion for energy.
In this chapter, an overview on the role of PBR design over the microalgae growth efficiency is presented. Also, the study of the growth of Chlorella sp. microalgae, locally isolated from freshwater from southern Algeria, is followed inside a lab-scale PBR under controlled conditions. Some process parameters such as dry weight, and optical density were followed during the process. The obtained results show clearly the effectiveness of the closed-controlled reactor for a better growth of the Chlorella sp. microalgae.
