“…Authors suggested that the increased in lipid production may be related to the stimulation of JA synthesis under combined nitrogen deficiency and SL treatment in microalgae. An exogenous JA supplementation was tested and led to the highest lipid content (57.12%) and productivity (322.65 mg.L À1 .d À1 ) under nitrogen stress combined with SL treatment, validating the role of JA in regulating lipid synthesis and oxidative stress response in microalgae (Song et al, 2020). Also, Zhao et al (2021) have demonstrated the effect of melatonin on lipid accumulation in Monoraphidium sp.…”

“…QLY-1 cultures and led to enhance lipid content and lipid productivity under 1mM induction compared (Song et al, 2019). Nevertheless, higher lipid content and lipid productivity were obtained in nitrogen deficiently without strigolactone induction (Song et al, 2020). Similar study performed on Nannochloropsis oceanica CASA CC201 have shown that treatment with 10 ppm of methyl jasmonate (MeJA) also promoted biomass and lipid yields, with an increase of 22% and 49% more than control (Udayan et al, 2020).…”

Research on lipid production in microalgae, especially to target biofuels, has been widely published in recent decades. This literature is mostly focused on the optimization of culture conditions, metabolic engineering, biorefinery and downstream processes. At the lab scale, lipid production is very promising concerning biofuels production based on microalgae due to their high lipid content. However, the accumulation of knowledge associated with the development of processes and technologies for the production of biomass and associated lipids has so far not achieved the hoped-for commercial success due to still too expensive operating costs compared to fossil fuels. This review aims to present the influence of various abiotic factors on the accumulation of lipids and lipid profile in microalgae, such as the depletion of the culture medium, temperature and light, but also most innovative like the induction by hormones. Other optimization procedures and the use of wastewater to improve the cost-viability are discussed in perspective.

“…Chemical genetic data demonstrated that Ca 2+ accumulation induced by rac-GR24 stimulates lipid accumulation by regulating the transcription levels of lipid biosynthesis-related genes and NO signaling. They also reported a 1.3-fold improvement in lipid productivity with the same rac-GR24 dosage under nitrogen-deficient conditions [15]. Compared to the control group, melatonin improved the lipid content of H. pluvialis LUGU by 49.5% under photoautotrophic conditions [32], and salicylic acid increased the total fatty acid content of H. pluvialis 192.80 by 36.0% under photoheterotrophic conditions [30].…”

“…Interestingly, rac-GR24 (0.2-5 µM) also promotes lipid accumulation in Monoraphidium sp. QLY-1 when CaCl 2 supplementation [14] or nitrogen deficiency [15] strategies are combined. These results suggest that, although cell growth and lipid biosynthesis are generally inversely related, rac-GR24 may help improve overall lipid productivity in other algal species if applied carefully.…”

Enhancement of Astaxanthin and Fatty Acid Production in Haematococcus pluvialis Using Strigolactone

et al. 2022

Improving the production rate of high-value nutraceutical compounds, such as astaxanthin and polyunsaturated fatty acids (PUFAs), is important for the commercialization of Haematococcus pluvialis biorefineries. Here, the effects of a phytohormone, strigolactone analog rac-GR24, on cell growth and astaxanthin and fatty acid biosynthesis in H. pluvialis were investigated. Four concentrations (2, 4, 6, and 8 µM) of rac-GR24 were initially added during 30 days of photoautotrophic cultivation. The addition of rac-GR24 improved cell number density and chlorophyll concentration in H. pluvialis cultures compared to the control; the optimal concentration was 8 µM. Despite a slightly reduced astaxanthin content of 30-d-old cyst cells, the astaxanthin production (26.1 ± 1.7 mg/L) improved by 21% compared to the rac-GR24-free control (21.6 ± 1.5 mg/L), owing to improved biomass production. Notably, at the highest dosage of 8 µM rac-GR24, the total fatty acid content of the treated H. pluvialis cells (899.8 pg/cell) was higher than that of the untreated cells (762.5 pg/cell), resulting in a significant increase in the total fatty acid production (361.6 ± 48.0 mg/L; 61% improvement over the control). The ratio of PUFAs, such as linoleic (C18:2) and linolenic (C18:3) acids, among total fatty acids was high (41.5–44.6% w/w) regardless of the rac-GR24 dose.
