Fig. 4From: Fine-tuned regulation of photosynthetic performance via γ-aminobutyric acid (GABA) supply coupled with high initial cell density culture for economic starch production in microalgaeSummary of the different effects of GABA on the photosynthetic physiology, stress regulation, and starch accumulation in T. subcordiformis exposed to nitrogen deprivation under NICD and HICD conditions. The summary was based on the results obtained on Day 4 under NICD with 0 vs. 5 mM GABA and HICD with 0 vs. 2.5 mM GABA which showed maximum starch production improvements, respectivelyBack to article page
