“…Thus, biodiesel, as a potential renewable alternative to fossil fuels, has gained increasing recognition [1]. Biodiesel has the potential to be carbon-neutral, as well as environmentally friendly with low emissions, and can be a viable alternative to conventional petrodiesel due to its similar fuel properties to petrodiesel [2]. More than 95% of biodiesel is produced from edible oils, which account for approximately 60-80% of the production costs [3].…”

Although Saitozyma podzolica Zwy2-3 can use the enzymatic hydrolysate of corn stalks treated with an ammonium carbonate-steam explosion (EHCS-ACSE) as a substrate for lipid accumulation, the inefficient conversion of sugars from EHCS-ACSE into lipids necessitates the further optimization of fermentation parameters. Response surface design was used to optimize the primary fermentation parameters. Under the optimized conditions of the reducing sugar concentration of 89.44 g/L, yeast extract concentration of 3.88 g/L, rotational speed of 219 rpm, and incubation time of 122 h, the maximum lipid production achieved 11.45 g/L, which was 2.28 times higher than the results of the previous study. In addition, lipid profiling showed the presence of four fatty acid methyl esters, with the highest percentage being 61.84% oleic acid, followed by 21.53% palmitic acid, 13.05% stearic acid, and 3.58% linoleic acid. It is noteworthy that the composition and relative abundance of microbial lipids remained constant under different culture conditions. The characteristics of Zwy2-3 biodiesel, such as the iodine value (62.09), cetane number (59.29), density (0.87 g/cm3), and oxidation stability (35.53), meet the international standards (ASTM D6751-02 and EN 14214) for biodiesel. The present study further demonstrated that S. podzolica Zwy2-3 can efficiently utilize EHCS-ACSE for microbial lipid accumulation, and its lipids have favorable qualities that make them suitable for biodiesel production.

Biodiesel is a reliable and promising replacement of fossil diesel. It is stable, less toxic and can be produced from sustainable resources, including a variety of raw materials. Currently, the most widely used are vegetable oils (edible and nonedible), due to their availability. The present paper considers the potential of obtaining fatty acid ethyl esters (FAEE) from corn oil, which is a byproduct of bioethanol production process. The ultimate outcome would definitely increase the profitability of the initial bioethanol production process. The biodiesel production process was implemented in two steps, due to the high content of free fatty acids of the obtained corn oil. The first step includes an acid-catalyzed esterification process and the second step comprises an alkali-catalyzed transesterification process to receive FAEE. Two different catalysts (sulfuric acid and p-toluene sulfonic acid) were utilized and compared each other in the esterification process, in order to cope with high acid number of the raw material. A comprehensive qualitative and quantitative analysis of both feedstock and biodiesel was performed using gas chromatography-mass spectrometry method. The obtained biodiesel was characterized by a significantly lower cloud point compared to the feedstock and high acid number.

“…Some of these feedstocks, despite being renewable, are also cheap [21] and available [22]. Besides, biodiesel physical and chemical properties such as flash point, cetane number, cloud point, and pour point are similar to that of conventional fuel [23].…”

Biodiesel, comprising mono alkyl fatty acid esters or methyl ethyl esters, is an encouraging option to fossil fuels or diesel produced from petroleum; it has comparable characteristics and its use has the potential to diminish carbon dioxide production and greenhouse gas emissions. Manufactured from recyclable and sustainable feedstocks, e.g., oils originating from vegetation, biodiesel has biodegradable properties and has no toxic impact on ecosystems. The evolution of biodiesel has been precipitated by the continuing environmental damage created by the deployment of fossil fuels. Biodiesel is predominantly synthesised via transesterification and esterification procedures. These involve a number of key constituents, i.e., the feedstock and catalytic agent, the proportion of methanol to oil, the circumstances of the reaction and the product segregation and purification processes. Elements that influence the yield and standard of the obtained biodiesel encompass the form and quantity of the feedstock and reaction catalyst, the proportion of alcohol to feedstock, the temperature of the reaction, and its duration. Contemporary research has evaluated the output of biodiesel reactors in terms of energy production and timely biodiesel manufacture. In order to synthesise biodiesel for industrial use efficaciously, it is essential to acknowledge the technological advances that have significant potential in this sector. The current paper therefore offers a review of contemporary progress, feedstock categorisation, and catalytic agents for the manufacture of biodiesel and production reactors, together with modernised processing techniques. The production reactor, form of catalyst, methods of synthesis, and feedstock standards are additionally subjects of discourse so as to detail a comprehensive setting pertaining to the chemical process. Numerous studies are ongoing in order to develop increasingly efficacious techniques for biodiesel manufacture; these acknowledge the use of solid catalytic agents and non-catalytic supercritical events. This review appraises the contemporary situation with respect to biodiesel production in a range of contexts. The spectrum of techniques for the efficacious manufacture of biodiesel encompasses production catalysed by homogeneous or heterogeneous enzymes or promoted by microwave or ultrasonic technologies. A description of the difficulties to be surmounted going forward in the sector is presented.
