“…Closed photobioreactors may be located indoors or outdoors (Sánchez Mirón et al, 1999;Pulz, 2001), but outdoor location is more common because it can make use of free sunlight. Design and operation of the microalgal biomass production systems have been discussed extensively (Terry and Raymond, 1985;Borowitzka, 1996;Pulz and Scheinbenbogen, 1998;Pulz, 2001;Pulz et al, 2001;Sánchez Mirón et al, 1999;Tredici, 1999). Here, we focus exclusively on issues relating with the harvest of the biomass and its downstream processing to recover intracellular metabolites.…”

Commercial production of intracellular microalgal metabolites requires the following: (1) largescale monoseptic production of the appropriate microalgal biomass; (2) recovery of the biomass from a relatively dilute broth; (3) extraction of the metabolite from the biomass; and (4) purification of the crude extract. This review examines the options available for recovery of the biomass and the intracellular metabolites from the biomass. Economics of monoseptic production of microalgae in photobioreactors and the downstream recovery of metabolites are discussed using eicosapentaenoic acid (EPA) recovery as a representative case study.

A helix tube photobioreactor with a volume of 10 L was designed and manufactured. The facade of the reactor was designed as three-layer frame. The illumination helixes units were 16, illumination area volume was 1.5 L, illuminate speciWc area was 95 m ¡1 . A marine micro-alga Dunaliella salina was used as a model organism in this study. Results showed that the optimum inoculum concentration was OD 630 = 0.15 and the optimum circulation rate of culture Xuid was 630 mL/h for the bioreactor. In continuous cultivation, in order to determine the optimum collection of alga solution for the highest yield of -carotene, three diVerent alga solution collection and addition fresh culture medium volumes were applied: 0.8, 1.5, 2.0 L/day. The biomass and extraction of -carotene were determined in diVerent cultivation periods. The result suggested that the optimum daily harvest of alga solution was 1.5 L/day for the cultivation of D. salina to obtain the highest production of -carotene.

Innovative technologies and sources of energy must be developed to replace fossil fuels and contribute to the reductions of emissions of greenhouse gases associated with their use. In this perspective, algal biofuels are generating substantial awareness in many countries. As of today, it has been shown that it is scientifically and technically possible to derive the desired energy products from algae in the laboratory. The question lies, however, in whether it is a technology that merits the support and development to overcome existing scalability challenges and make it economically feasible. In this context, the overall purpose of this study is to provide an integrated assessment of the potential of microalgae as a source to produce biofuels, while confronting it with competing emerging biofuel technologies. It is intended to provide a comprehensive state of technology summary for producing fuels from algal feedstocks and to draw some insights upon the feasibility and technoeconomic challenges associated with scaling up of processes.
