“…This result suggests the possibility to scale‐up this strategy to industrial production, and offers the best economic results published until today. El Arroussi et al and Jusoh et al proposed, separately (2015), another substance for this purpose: 3‐indolacetic acid (IAA) . However, the cost of IAA (US$2.82 per gram) is considerably higher than that of 2,4‐D (US$0.32 per gram).…”

Some studies have described the use of phytohormones in microalgal culture for the production of biodiesel or selected fatty acids. However, no study has determined the amount of phytohormones that maximizes lipid yield. We determined the optimal concentration of auxins and gibberellins (which is between 40 and 60 μM) in two strains (Scenedemus abundans and Chlorella ellipsoidea) suitable for biodiesel production. More than 3-fold increment was reached with S. abundans and near 7-fold increment with C. ellipsoidea. Furthermore, this work suggests that the improved growth of the microalgae in the presence of the phytohormones was due to a reduction in the level of reactive oxygen species (ROS) in the cells. An economic analysis showed that, due to its low cost, auxin offers a positive cost-benefit balance and therefore could be used at large scale. © 2016 American Institute of Chemical Engineers Biotechnol.

“…A stepwise strategy was also conducted, in which Dunaliella tertiolecta cells were cultured with an addition of 2,4-D at the first step, boosting cell division and increasing biomass productivity by 40%. At the second step, the salt stress remarkably raised lipid content from 24 to 70% [28]. …”

Phytohormones and Effects on Growth and Metabolites of Microalgae: A Review

et al. 2018

View full text Add to dashboard Cite

Microalgae cultivation is booming in agriculture, aquaculture, and bioenergy sectors. A wide range of bioactive compounds with attractive properties can be produced with microalgae, including pigments, vitamins, proteins, carbohydrates, and lipids. The biofuel yields from microalgae can exceed the yields obtained with energy crops by 10-100 times. Therefore, such cultivation is promising for the regulation of the biosynthesis of microalagae with phytohormones, which can enhance the production of high-valued bioproducts. This review reports the effect of auxins, abscisic acid, cytokinins, gibberellins, and ethylene on microalgal growth and metabolites, as well as the crosstalk of different phytohormones. The use of phytohormones is also promising because it can also reduce the inputs necessary to grow the selected microalgae and maximize the yields.

“…2 depicts that, the highest yeast growth was obtained as 7.3 g/L when the fermentation medium was prepared with the Dunaliella cells which were cultivated in the presence of 15% NaCl concentration. Similar NaCl concentrations were used for cultivating Dunaliella cells in the literature (Arroussi et al, 2015).…”
