Abstract

The present study involved the designing of a culture process and the evaluation of productivity of oil products from a highly oleaginous marine diatom, Fistulifera sp. JPCC DA0580, which had been cultured in a commercial-scale factory. The culture facility had a capacity of 48,000L and held 96 flat-type 500-L photobioreactors (PBRs) equipped with artificial light, which secures a stable, perennial supply of the products. A 10days culture that had reached a cell density of 6.5g dry weight L-1 possessing a cellular oil content of 48% (wt/wt) was found to provide the highest oil yield. On considering a production area of 1500m2, annual algal mass and oil productivity is 68.7 and 33.3tha-1year-1, respectively. This study thus provides a reproducible prediction of a theoretical maximum oil yield from a highly oleaginous microalgal strain based on industrially practical production area.
