Abstract<\/strong><\/p>\n

The marine PrasinophyteTetraselmis may be cultured under both mixotrophic (photoheterotrophic) and heterotrophic conditions. The growth rate was slightly lower, and pigment levels and lipid composition were radically affected on heterotrophic culture in 1 L fermenters. Total chlorophyll levels of dark grown cultures were less than 1% of those observed in mixotrophically grown cells, the chlorophylla : b ratio also decreased as did the carotenoid content. In addition, the total amounts of lipids including polyunsaturated fatty-acids were also lower in heterotrophically cultured cells: 6.4 mg g\u20131 (dried alga) and 0.35 mg g\u20131 (dried alga); as compared to 37.1 mg g\u20131 (dried alga) and 18.5 mg g\u20131 (dried alga), for cells grown in the light. However, gross morphology and final yield (>16 g l\u20131) were relatively unaffected. The algae produced were spray-dried and tested for their suitability as an aquaculture feed.<\/p>\n

Key words algal biotechnology – heterotrophic culture – Tetraselmis – lipids – pigments – aquaculture<\/p>\n

About Oilgae – Oilgae – Oil & Biodiesel from Algae<\/a><\/b> has a focus on biodiesel production from algae while also discussing alternative energy in general. Algae present an exciting possibility as a feedstock for biodiesel, and when you realise that oil was originally formed from algae – among other related plants – you think “Hey! Why not oil again from algae!”<\/p>\n","protected":false},"excerpt":{"rendered":"
