Samples B ndash H represent various treatments

This lipid fraction amounted to 33% of the original dry weight of the algae. Its contaminant levels were significantly reduced compared to the parent algae, yet Na and K levels remained too high to include Sample B in FCC feed at even a 2% level (see Table 1). For the Nannochloropsis strain used here, earlier testing showed that for ethanol extractions, pre-milling the algae made no significant difference in the ethanol extraction results, since the ethanol tended to swell and rupture the cells.
