I Maximum Growth , I Ontimal I Ontimal , , I Optimal Medi he lipid production potential of these strains was evaluated by the use of th iU m Tyne fluorometric Nile Red assay. In Type I/55 medium, 49 strains had a higher apparent lipid content after 2 days of N-deficient growth, whereas 13 strains had the same or lower apparent lipid levels in response to N deficiency. In Type II/55 medium, 42
strains had higher lipid levels, and 7 strains had lower or unchanged lipid levels as a The strains exhibiting the highest Nile Red fluorescence levels are shown in Table consequence of N deficiency. Of note was that the mean lipid level in cells grown in II.A.3. All of these strains are diatoms, confirming the propensity of this group to Type II/55 medium was nearly twice that of Type I/55-grown cells. accumulate lipids.
