Table 1 Comparison of photoautotrophic monocultures of the DHA-producing microalgae T. lutea and the EPA-producing M. salina with a co-cultivation of the two microalgae at a harvest time after 8Â days (consumption of initially supplied nitrate in co-culture) relative to the illuminated surface of the flat-plate gas-lift photobioreactors
