“…One of the important phenomena associated with microalgae is that it can provide lipid content and mostly in the range of 20%-45% and reaches as high as 85%. 53 Therefore, we used in our present study microalgae (Dunaliella salina) extracted oil as the raw material for the production of biodiesel through transesterification. The cultivation of Dunaliella salina has been reported earlier from our laboratory.…”

Development of a new and sustainable catalyst is necessary to the society for providing economical technology. Surface modification of nanometal oxides is one of the rapidly growing methods for developing a sustainable catalyst with attractive properties than their parent oxide. In this work, surface‐modified nickel ferrites have been carried out using 4,4′‐biphenyldisulfonic acid (BPDSA) as the linker. Thus, obtained modified material has been characterized using different techniques such as DLS, FT‐IR, TGA, XRD, VSM, and XPS. This well‐characterized, stable, robust, recyclable material offers a good conversion in the fatty acid, that is, oleic acid esterification in the presence of methanol in a short period of time (3.0 h). Based on the kinetic study in the oleic acid esterification, it fits in the pseudo first‐order kinetics, and activation energy was found to be 60.0 kJ/mol. Further, the potentiality of our catalyst was also tested in the transesterification of various raw materials like mustard oil, olive oil, almond oil, and neem oil. In addition, it provides an excellent conversion with microalgae lipid extraction for the production of biodiesel. The kinematic viscosity of the methyl oleate (biodiesel) has been found to be 5.0426 mm2/s at 25°C whereas the dynamic viscosity is 6.0511 mPa, which is nearly the same as biodiesel obtained from Dunaliella salina, microalgae lipid.

Biodiesel is nontoxic and perishable and is created by combining alcohol with edible fat, animal fat, or used cooking oil. Considering the food issues, microalgae gain the utmost attention to be used as biofuel producers. According to the study, biomass-based biofuels offer excellent potential to address energy scarcity in a sustainable manner [3]. The environmentally beneficial method of producing biodiesel has attracted the interest of scientists worldwide [4]. The effectiveness and cost-reduction of microalgal biodiesel synthesis continue to be major barriers to its optimal development because it is a sequential process [5]. The costliest of the four production processes is cultivation (>40% of the overall cost). Among the four production methods, cultivation stands out as the most expensive (>40% of the total expenses). To achieve a significant biomass concentration, it is essential to gather microalgae [6]. Consequently, substantial quantities of water need to be acquired from the production procedures, which entails financial expenditure and energy consumption. It is estimated that around 30% of the overall production cost could be attributed to the expenses related to harvesting [7]. To accomplish energy-effective

Despite the increasing interest in biodiesel production from microalgae, the high cost of multistage production processes still hinders its commercialization. The high oil productivity of microalgae and their ability to grow rapidly under harsh conditions and in saline water make them a favorable feedstock for biodiesel production. In this review, conventional methods of producing biodiesel from microalgae are thoroughly discussed and compared to state‐of‐the‐art technologies. Considerable emphasis has been put on the adoption of biocatalysts as alternative greener and more effective catalysts. Challenges facing the biocatalytic process and innovative ways to overcome them are also presented. The main focus is on the in‐situ biodiesel production processes, which are promising to pave the way for industrial application of microalgae‐to‐biodiesel process. The use of state‐of the‐art thermoresponsive switchable solvents, coupled with immobilized lipase, for simultaneous cell disruption, oil extraction‐reaction, and product separation in one pot has shown to be highly favorable. Because enzymes are expensive, finding ways to enhance their stability and reusability for a greater number of cycles is essential for the process to be economically viable and competitive.
