From: Physiological and transcriptome analysis elucidates the metabolic mechanism of versatile Porphyridium purpureum under nitrogen deprivation for exopolysaccharides accumulation

Fig. 2

Changes of biochemical macromolecules and high-value active substances in P. purpureum under normal and nitrogen-deficient conditions. a Changes in total soluble protein (TSP) content. b Changes in B-phycoerythrin content and yield (concentration). c Changes in carbohydrate content. d Changes in exopolysaccharide content and yield (concentration). e Total lipid (TL) content of normal and the nitrogen-deficient cells at day 20. f Fatty acids (FAs) profiles of normal and the nitrogen-deficient cells at day 20. ND means nitrogen deprivation. Data are expressed as mean  ±  SD (n  =  3). *Significant difference (t test, p  <  0.05), **significant difference (t test, p  <  0.01), ***significant difference (t test, p  <  0.001)
