dc.description.abstract Toxic dinoflagellates are important in natural ecosystems and are of global economic significance because of the impact of toxic blooms on aquaculture and human health. Both the organisms and the toxins they produce have potential for biotechnology applications. We investigated autotrophic growth of a toxic dinoflagellate, Alexandrium minutum, in three different high biomass culture systems, assessing growth, productivity and toxin production. The systems used were: aerated and non-aerated 2-L Erlenmeyer flasks; 0.5-L glass aerated tubes; and a 4-L laboratory scale alveolar panel photobioreactor. A range of indicators was used to assess growth in these systems. Alexandrium minutum grew well in all culture conditions investigated, with a marked increase in both biomass and productivity in response to aeration. The highest cell concentration (4.9 x 10(5) cells mL(-1)) and productivity (2.6 x 10(4) cells mL(-1) d(-1)) was achieved in the aerated glass culture tubes. Stable growth of A. minutum in the laboratory scale alveolar panel photobioreactor was maintained over a period of five months, with a maximum cell concentration of 3.3 x 10(5) cells mL(-1), a mean productivity of 1.4 x 10(4) cells mL(-1) d(-1), and toxin production of approximately 20 mug L(-1) d(-1) with weekly harvesting.
