Effects of nitrogen depletion on storage product accumulation in D. tertiolecta.
The starch (a), neutral lipids (b), total lipids (c), intracellular glycerol (d) and extracellular glycerol (e) content in D. tertiolecta cells under nitrogen-replete and nitrogen-deplete conditions in different phases of cell growth. Proportion of starch, total lipids and intracellular glycerol are presented as a percentage of dry cell weight (f). Error bars represent standard deviations from three independent biological replicates. Asterisks indicate statistically significant differences between N-replete and N-deplete samples after two-tailed t-tests (*p value ≤ 0.05; **p value ≤ 0.01).
