“…C. reinhardtii CC-124 shows an increase in lipids during sulfur deprivation of approximately 35% [ 69 ]. These results are similar to those found by Gómez-De la Torre et al (2023) [ 70 ], who reported a higher lipid content in sulfur and phosphorus limitation conditions, showing that the concentration of both macroelements in microalgae culture is highly relevant for the production of lipids. Also, 216 mg g −1 (>50% greater than control) was obtained under low concentration [S − ] conditions at the 10th culture day in C. vulgaris .…”

“…C. vulgaris culture observed an increase in palmitic acid (>50% greater), linoleic acid (>50% greater), and arachidonic acid (>50% greater) compared to control at low sulfur concentration [S − ] ( Figure 5 e). These results are similar to those found with Chlorella vulgaris under sulfur-deprived medium, where an increase in palmitic, oleic, and linoleic acid were observed [ 70 ]. In addition, at high sulfur concentration [S + ], higher concentrations of palmitic acid (49% greater) and α-linoleic acid (>50% greater) were determined compared to the control.…”

The production of biomolecules by microalgae has a wide range of applications in the development of various materials and products, such as biodiesel, food supplements, and cosmetics. Microalgae biomass can be produced using waste and in a smaller space than other types of crops (e.g., soja, corn), which shows microalgae’s great potential as a source of biomass. Among the produced biomolecules of greatest interest are carbohydrates, proteins, lipids, and fatty acids. In this study, the production of these biomolecules was determined in two strains of microalgae (Chlamydomonas reinhardtii and Chlorella vulgaris) when exposed to different concentrations of nitrogen, phosphorus, and sulfur. Results show a significant microalgal growth (3.69 g L−1) and carbohydrates (163 mg g−1) increase in C. reinhardtii under low nitrogen concentration. Also, higher lipids content was produced under low sulfur concentration (246 mg g−1). It was observed that sulfur variation could affect in a negative way proteins production in C. reinhardtii culture. In the case of C. vulgaris, a higher biomass production was obtained in the standard culture medium (1.37 g L−1), and under a low-phosphorus condition, C. vulgaris produced a higher lipids concentration (248 mg g−1). It was observed that a low concentration of nitrogen had a better effect on the accumulation of fatty acid methyl esters (FAMEs) (C16-C18) in both microalgae. These results lead us to visualize the effects that the variation in macronutrients can have on the growth of microalgae and their possible utility for the production of microalgae-based subproducts.
