“…Fuel with a high CN is easily flammable and can burn quickly. A comparable study with the same microalgae species Hopkins et al (2019) reported that the fatty acid dispersion of the microalgae oil is rich in C16 and C18. They have also demonstrated its suitability for biodiesel production.…”

“…According to the author's knowledge, limited studies are examining the behavior and lipid production potential of Dunaliella tertiolecta under salt starvation. A comparable single study, Hopkins et al (2019) reported that the lipid which they obtained from microalgae was suitable as a raw material source for biofuel manufacture. Besides by reaching the highest cell concentration for Dunaliella species in f2 nutrient media containing 120 g / L salinity.…”

The valuable components from microalgae are increasingly used in the synthesis of several commercial chemicals. Lipids from major microalgae crops are similar to lipids obtained from oilseed plants and can be converted into biodiesel, moreover, microalgae are more advantageous than plants in oil production in many ways. Therefore, oil and biodiesel production technology from microalgae is a current and interesting research topic. The effect of salinity in the nutrient medium on the growth and lipid productivity of marine microalgae Dunaliella tertiolecta was examined. The usability of Marmara Seawater (MSW) as a growth medium and its suitability for microalgae were also investigated. The highest cell concentration (1.53 gdw / L), growth rate (μmax=0.006 h -1 ) and oil productivity (12.8 (g / L. Day) (10 -3 )) in nutrient medium (5g) were obtained. On the other hand, the cetane (CN) number was calculated according to the dominant arachidic acid (C20:0), it was determined as 74.9 and the mean molecular weight of the oil was determined as 849.1 g / mol. According to the experimental results, it is predicted that microalgae lipids will be widely used as an alternative to vegetable oils soon as raw materials.

“…Further, algae can remove various constituents and pollutants from water and wastewater such as nutrients, heavy metals, and dissolved and complex organic chemicals via biosorption and bioaccumulation. Metal biosorption is facilitated by the negatively charged extracellular polymeric substances (EPS) on the surface microalgae [17,61,62]. Microalgae also require some elements, typically found in PW, to grow [5].…”

Biological-Based Produced Water Treatment Using Microalgae: Challenges and Efficiency

et al. 2022

Produced water (PW) is the most significant waste stream generated in the oil and gas industries. The generated PW has the potential to be a useful water source rather than waste. While a variety of technologies can be used for the treatment of PW for reuse, biological-based technologies are an effective and sustainable remediation method. Specifically, microalgae, which are a cost-effective and sustainable process that use nutrients to eliminate organic pollutants from PW during the bioremediation process. In these treatment processes, microalgae grow in PW free of charge, eliminate pollutants, and generate clean water that can be recycled and reused. This helps to reduce CO2 levels in the atmosphere while simultaneously producing biofuels, other useful chemicals, and added-value products. As such, this review focuses on PW generation in the oil and gas industry, PW characteristics, and examines the available technologies that can be used for PW remediation, with specific attention to algal-based technologies. In addition, the various aspects of algae growth and cultivation in PW, the effect of growth conditions, water quality parameters, and the corresponding treatment performance are presented. Lastly, this review emphasizes the bioremediation of PW using algae and highlights how to harvest algae that can be processed to generate biofuels for added-value products as a sustainable approach.

“…The development of economically viable microalgal cultivation systems is facilitated by several factors, like the ability of the microalgae to grow on unclaimed, cheap wastewater, their remediation efficiency of dissolved pollutants present in the wastewater, and their capacity to accumulate biomass that can be cost-effectively harvested and transformed into valuable products, for example biodiesel [12,[14][15][16][17]. To achieve such feats, studies have focused on assessing the growth modes of algal-microbial communities or selected species combinations in various wastewater sources [8,[18][19][20][21][22][23]. These studies have demonstrated that wastewater, including PW, can be a highly efficient cultivation medium for many species, sometimes achieving substantive improvements in water quality.…”

While oilfield produced water (PW) is one of the largest, unclaimed wastewater streams of the oil industry, it could potentially be used as a cultivation medium for microalgae. Microalgae could help with the remediation of this water while also delivering biomass that can be transformed into valuable byproducts such as biofuels. The coupling of these two purposes is expected to cut production costs of biofuels while aiding environmental protection. In this study, we compared the cultivation capacity of the marine model diatom Phaeodactylum tricornutum in media at varying salinities and in media composed of PW from two oilfields in the Central Valley of California that differed drastically in the concentration of inorganic and organic constituents. Specifically, we measured the carrying capacity of these media, the maximum growth rates of P. tricornutum, its cellular lipid accumulation capacity, and its capacity to remediate the most polluted PW source. Our study shows that P. tricornutum can successfully adjust to the tested cultivation media through processes of short-term acclimation and long-term adaptation. Furthermore, the cultivation of P. tricornutum in the most heavily polluted PW source led to significant increases in cell yield and improved photosynthetic capacity during the stationary phase, which could be attributed chiefly to the higher levels of nitrate present in this PW source. Chemical water analyses also demonstrated the capability of P. tricornutum to remediate major nutrient content and potentially harmful elements like fluorine and copper. Because P. tricornutum is amenable to advanced genetic engineering, which could be taken advantage of to improve its cultivation resilience and productivity in an economic setting, we propose this study as a step towards essential follow-up studies that will identify the genetic regulation behind its growth in oilfield PW media and its remediation of the PW constituents.
