“…Acid-catalyzed transesterifications are generally slower than alkaline-catalyzed reactions and have lower yields in similar reaction conditions (Kialashaki et al, 2019).

Although, the results are promising for the use of microalgae biomass with potential for biodiesel generation.…”

The production of biofuels through microalgae biomass represents a new generation of raw materials from renewable sources to meet society’s clamors and growing insertion in the market of fuels from products that could grant the planet a sustainable future. The present study assesses the biomass obtained from microalgae Chlorella vulgaris when grown in urban wastewater, extracting the lipids from the biomass and performing Gas Chromatography analysis of fatty acid methyl esters (FAME) composition after submitting the lipids through the transesterification process. The microalgae cultivation was monitored through chlorophyll (a) analysis and the highest cell growth was 845.8 µg L-1 using urban wastewater as growth medium. The nutrients of interest were monitored for primary concentration of 8.06 ± 0.06 mg L-1 of ammoniacal nitrogen, 12.27 ± 0.27 mg L-1 of nitrate and 21.22 ± 0.85 mg L-1 of phosphate, reducing about 99% of ammoniacal nitrogen and nitrate, along with reducing 87% of phosphate. The lipid constitution extracted from 3.7 g of dry biomass of Chlorella vulgaris after cultivation using urban wastewater, was 7.7%. The lipids extracted from the Chlorella vulgaris biomass are suitable biodiesel production regarding the amounts of FAMEs identified, after the analysis carried out, the comparison of the results obtained with other studies and the hypotheses evaluation.

“…Although phytohormone supplementation is considered a promising strategy for improving the e ciency of microalgae cultivation, it is necessary to optimize the concentration of these substances to each kind of microalgae because small variations in concentration can result in great changes to the cells [9,10]. In the literature, there are many relates to phytohormone supplementation in the cultivation of eukaryotic microalgae genres as Chlorella [11][12][13][14][15][16] and Scenedesmus [15,17,18]. Nevertheless, there are fewer studies about the use of this strategy to increase the cyanobacteria biomass [19][20][21], and it was found just one with Spirulina [22].…”

Application of microalgae in industries is limited by their low biomass production and low macromolecule content. Phytohormones are being studied to solve these problems, however is necessary to define conditions that enhance the results for this kind of cultivation strategy. The increasing of the contact time between substances and cells can be a factor of the improvement in the phytohormone uptake by microalgae. We hypothesize that by decreasing the sampling frequency for monitoring culture parameters, we would also be interfering less in the uptake of phytohormones by microalgae. Therefore, the present study aimed to investigate the influence of sampling frequency on the production of biomass and biomolecules of Spirulina sp. LEB 18 in cultivations supplemented with trans-zeatin and indole-3-acetic acid (IAA). Treatments with lower sampling frequency and supplementation of 1 mg L− 1 IAA enhanced biomass accumulation by 75 %, carbohydrate content by 50 %, and protein content by 30 % as compared to control experiment daily sampling. In addition, sampling every 10 days with 0,01 mg L− 1 IAA supplementation increased the lipid content by 51 % as compared with the experiment without phytohormone and daily sample removal. Therefore, we developed a new strategy to supplement phytohormones and improve microalgal production. This investigation presented a cultivation system efficient, which can be easy to implement in industries because of no need to change the operational aspects of the cultivation. Furthermore, the strategy will can be very useful to enhance the production capacity of microalgae on a large-scale.

“…For example, Jiang et al (2015) investigated that DA-6 accelerated the microalgae growth and simultaneously improved the quality and quantity of lipid for biodiesel production. Zhang et al (2014) confirmed that the mixture of ethephon and diethyl aminoethyl hexanoate (DA-6) could improve lodging resistance and yield in maize.In addition, a mixture of DA-6 and indole-3-acetic acid could promote the growth and fatty acid content of some microalgae for biodiesel production (Salama et al, 2017).…”

Potassium fulvic acid and diethyl aminoethyl hexanoate (DA-6) are two kinds of growth regulators with yield increasing and quality improving. There are few reports on the effects of adding potassium fulvic acid and DA-6 in nutrient solution on the growth of soilless culture of vegetables. In this study, tomato was used as the test material to add different concentrations of potassium fulvic acid (0, 15, 30 mg•L 1 ) and DA-6 (0, 2.5, 5 mg•L 1 ) into nutrient solution of total nutrient minerals, so as to study the effects of adding two growth-regulating substances to nutrient solution of total nutrient mineral on the growth, yield and quality of tomato in soilless cultivation with rock wool in solar greenhouse. The results showed that: With no addition of potassium fulvic acid and DA-6 as the control, in the early stage of bearing fruit, the potassium fulvic acid added with 30 mg•L 1 nutrient solution alone had an inhibitory effect on tomato plant height and the inhibition could be alleviated by adding DA-6. When 30 mg•L 1 potassium fulvic acid and DA-6 were added together, the fresh quality of single stem and dry quality of single leaf in the early and middle stage of tomato bearing fruit were significantly improved. 15 mg•L 1 potassium fulvic acid and 2.5 mg•L  DA-6 had the best effect on the total yield of a single plant, which was 21.77% higher than that of the control. 15 mg•L 1 potassium fulvic acid and DA-6 could significantly increase the C content and sugar acid ratio of tomato fruit. To summarize, 15 mg•L 1 potassium fulvic acid and 2.5 mg•L 1 DA-6 showed synergistic effect, which has the best improvement effect on the growth, yield and quality of best.
