Lipid Extraction from Spirulina sp. and Schizochytrium sp. Using Supercritical CO with Methanol

Figure 8

Comparison of simulated lipid extraction yields (lines) and experimental lipid extraction yields (symbols) under different operating pressures and the test when methanol was added. (a) Schizochytrium sp.: red square, 4000 psi with 200 ml of methanol, r² = 0.985; blue circle, 4000 psi, r² = 0.957; green triangle, 2000 psi, r² = 0.885. (b) Spirulina sp.: red square, 4000 psi with 200 ml of methanol, r² = 0.992; blue circle, 4000 psi, r² = 0.974; green triangle, 2000 psi, r² = 0.608. Error bars represent one standard error from three replicates.
