E Ganuza,M S Izquierdo,

Lipid and docosahexaenoic acid (DHA) accumulation into Schizochytrium G13/2S was studied under batch and continuous culture. Different glucose and glutamate concentrations were supplemented in a defined medium. During batch cultivation, lipid accumulation, 35% total fatty acids (TFA) occurred at the arithmetic growth phase but ceased when cell growth stopped. When continuous culture was performed under different glutamate concentrations, nitrogen-growth-limiting conditions induced the accumulation of 30-28% TFA in Schizochytrium. As the dilution rate decreased from 0.08 to 0.02 h(-1), both cell dry weight and TFA content of the cell increased. Under a constant dilution rate of 0.04 h(-1), carbon-limiting conditions decreased the TFA to 22%. Fatty acid profile was not affected by the different nutrient concentrations provided during continuous culture. Consequently, lipid accumulation can be induced through the carbon and nitrogen source concentration in the medium to maximise the TFA and subsequently DHA productivity by this microorganism.
