Microalgae are very efficient solar energy converters and they can produce a great variety of second metabolite productions. Microalgae have been suggested as very good candidates for fuel production because of their advantages of higher photosynthetic efficiency, higher biomass production and faster growth compared to other energy crop. Many researches have been conducted to take advantage of these properties through algal mass culture. Many applications for microalgae have been described in the literature, these microorganisms are still of minor economic importance when culture at large scale. Industrial reactors for algal culture at present are commonly designed as open race-ways (where culture is circulated by a paddle-wheel). Technical and biological limitations of these open systems have given rise to the development of enclosed photoreactors (made of transparent tubes, sleeves or vessels and where light source may be natural or artificial). In this study, the 100L flat panel reactor is considered to culture Tetraselmis sp. KCTC 12236BP in large scale. Flat panel reactor used in this experiment is transparent vessel in which mixing is carried out directly in the reactor with air sparging. In this kind of photobioreactor, light dilution is obtained by applying larger specific surface and self-shading of the panels. In this way, it is possible to achieve a higher photosynthetic efficiency and high biomass as well.
