PG - 428-33 AB - Outdoor culture of the thermophilic cyanobacterium Synechocystis aquatilis SI-2 with a vertical flat-plate photobioreactor (VFPP) was studied during the period of January to August of 1999 in the northern region of Japan (Kamaishi, Iwate, 39 degrees N, 142 degrees E). The aim of this study was to investigate the CO2 fixation ability of the VFPP device under various irradiation conditions. An average biomass productivity of over 30 g m(-2) day(-1), which corresponds to a CO2 fixation rate of 50 g m(-2) day(-1), was achieved during this period with a 192-l scale culture. The effects on biomass productivity of the light path, height of the reactor, cell concentration and irradiation were also investigated. Variation of the optimal cell concentration to achieve the highest productivity for outdoor operation is discussed. A cell concentration of 1-2 g l(-1) was found to be most suitable for the irradiation range of 1-12 MJ m(-2) day(-1) under the experimental conditions used.
