We have screened six species of marine microalga for their ability to produce the important dietary lipid docosahexaenoic acid (DHA). Isochrysis aff. galbana T-Iso (UTEX LB 2307), which produced DHA in the highest quantities (5.4 mg-g-1), was grown in a new type of closed photobioreactor in which efficient light distribution was achieved using light-diffusing optical fibres. The optimal temperature and light intensity for DHA production were determined and a maximal DHA production of 4.3 mg-l was achieved, twofold greater than that obtained using conventional culture methods. In addition, the DHA content could be enhanced by low temperature or dark incubation of the culture after growth.
