HIGH CELL DENSITY OF HETEROTROPHIC ALGAE

The competitiveness of using heterotrophic algae over photoautotrophic ones for oil production rests largely with the high yield and productivity of biomass as well as of oil in heterotrophic cultivation modes. The high cell density of heterotrophic algae can be achieved by the employment of fed-batch, continuous, and cell-recycle culture strategies that are widely used in the fermentation of bacteria or yeasts.
