“…The lipid content determined in the C. minutissima biomass in the present study is shown in Table 3. Oil from algal biomass is commonly used to produce biodiesel [46]. The advantage of lipids obtained from C. minutissima cells is their composition and appropriate fatty acid profile, mainly high content of triacylglycerols, which makes them extremely useful in the production of this biofuel [47].…”

Aquaculture wastewater contains a huge amount of substances that can cause environmental pollution. However, microalgae can absorb these compounds and convert them into useful biomass. In this study, Chlorella minutissima was grown in the wastewater resulting from saline aquaculture. The microalgae were found to effectively utilize nitrogen and phosphorus in the wastewater for its growth. During wastewater treatment, the cell density increased almost fivefold compared to the initial value (OD 680 0.502). Moreover, batch culture resulted in the maximum biomass concentration and productivity of 4.77 g/L and 0.55 g/L/day, respectively. The contents of total nitrogen and total phosphorus in wastewater decreased by 88% and over 99%, respectively. In addition, the content of N-NO 3 was reduced by 88.6%, N-NO 2 by 74.3%, and dissolved orthophosphates (V) by 99%. At the beginning and throughout the experiment, the content of N-NH 4 in wastewater remained below 0.05 mg/L. Furthermore, a high lipid content of 46.4% (w/w) was also obtained from the studied microalgae.

“…Scheme 1 was designed to facilitate the understanding of the results and discussions. Remarkably, cost reduction in biodiesel production has been a major challenge for more than 20 years [49]. In this sense, efforts have been made to enable the use of a wide range of raw materials, to optimize the processes of production and to investigate more efficient catalysts.…”

“…During the enzymatic transesterification for the production of biodiesel, one of the products formed is glycerol, which can be deposited on the surface of the enzyme, forming an outer layer preventing contact between the substrate and the enzyme active site, reducing the catalytic activity of the enzyme [1,40]. Remarkably, cost reduction in biodiesel production has been a major challenge for more than 20 years [49]. In this sense, efforts have been made to enable the use of a wide range of raw materials, to optimize the processes of production and to investigate more efficient catalysts.…”

Residual oil from babassu (Orbignya sp.), a low-cost raw material, was used in the enzymatic esterification for biodiesel production, using lipase B from Candida antarctica (Novozym® 435) and ethanol. For the first time in the literature, residual babassu oil and Novozym® 435 are being investigated to obtain biodiesel. In this communication, response surface methodology (RSM) and a central composite design (CCD) were used to optimize the esterification and study the effects of four factors (molar ratio (1:1–1:16, free fatty acids (FFAs) /alcohol), temperature (30–50 °C), biocatalyst content (0.05–0.15 g) and reaction time (2–6 h)) in the conversion into fatty acid ethyl esters. Under optimized conditions (1:18 molar ratio (FFAs/alcohol), 0.14 g of Novozym® 435, 48 °C and 4 h), the conversion into ethyl esters was 96.8%. It was found that after 10 consecutive cycles of esterification under optimal conditions, Novozym® 435 showed a maximum loss of activity of 5.8%, suggesting a very small change in the support/enzyme ratio proved by Fourier Transform Infrared (FTIR) spectroscopy and insignificant changes in the surface of Novozym® 435 proved by scanning electron microscopy (SEM) after the 10 consecutive cycles of esterification.

“…The physicochemical properties and biodiesel quality were examined according to the American Standards for Testing Materials (ASTM). Rezania et al (2019) reported that the main physicochemical characteristics of biodiesel are flash point, pure point, cloud point, cetane number, viscosity, and density. These properties are affected by the compositional profile of biodiesel.…”

In this research, Capparis spinosa oil was used as a feedstock for biodiesel production in the presence of NaOH/NaX as a nano heterogeneous catalyst. The NaOH/NaX catalyst was characterized by XRD, SEM, and BET analyses. The transesterification reaction was optimized through response surface methodology (RSM) based on the central composite design (CCD) of experiments. The effects of key variables of catalyst weight, methanol to oil molar ratio, and time on the reaction were studied, and a precise discussion about the impact of each process variable on the biodiesel yield was carried out. The highest biodiesel yield was 90.33% for the optimum reaction conditions that include a constant temperature of 60 °C, methanol to oil molar ratio of 6.7:1, catalyst weight of 2.3 wt%, and reaction time of 1.24 h. Furthermore, all physicochemical properties of the produced biodiesel were matched to the ASTM standard. Based on the obtained results, Capparis spinosa oil is a suitable source for biodiesel production.
