Biodiesel has become increasingly important in recent years as a potential substitute for petroleum diesel. Different techniques and catalysts have been developed and widely investigated for biodiesel production via enzymatic biocatalysis. In this review, we conducted a bibliometric analysis to examine the global scenario and identify trends in lipase‐catalyzed biodiesel production in the past three decades. Challenges, advantages, disadvantages, and novel methods are also discussed. Publication frequency increased over the studied period, with China, Brazil, and India emerging as the most productive countries in terms of total number of publications and number of publications per journal. Papers from the field of bioenergy and bioprocesses received the highest number of citations. Keyword analysis revealed that immobilized lipase (magnetic nanoparticles and cross‐linked enzyme aggregates), different feedstocks, ionic liquids, ultrasonication, and metabolic engineering were relevant to lipase‐catalyzed biodiesel production. It is concluded that the research emphasis on biodiesel production is moving toward the use of non‐edible oils, ultrasound, and ionic liquids for achieving high‐enzyme activity and substrate conversion. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd

“…Homogeneous alkali/acid catalysts are often used in industrial catalysis. Generally, triglycerides are reacted with ethanol under the catalysis of KOH or NaOH to generate FAEE and by-product glycerol (Kuan et al, 2019) (Balat, 2011).The reaction temperature and time have received extensive attention from researchers. Homogeneous base-catalyzed transesterification is mainly a one-step catalytic process, and the commonly used catalysts are NaOH and KOH (Balat and Management, 2011).…”

Pinolenic acid is a polyunsaturated fatty acid present only in Pinus koraiensis Sieb. et Zucc seed oil. It can inhibit and eliminate the adverse effects of other fatty acids on the body. In order to solve the structural instability problem of polyunsaturated fatty acids, pinolenic acid of P. koraiensis seed oil was effectively isolated and purified by the integrated strategy of ethyl esterification followed by urea inclusion for the first time. Under the optimal conditions after the Box-Benhnken Design experimental, ethyl pinolenate with high purity 94.95% could be obtained, and the average content of PNAEE can still reach 86.18%. Then ethyl pinolenate was characterized by Gas chromatography-mass spectrometry, Fourier transform infrared, and Nuclear magnetic resonance spectra, results showed that ethyl pinolenate was successfully prepared. In addition, the hypolipidemic activity of ethyl pinolenate had been tested in vivo and showed that ethyl pinolenate had obvious hypolipidemic activity. The new strategy for high purity ethyl pinolenate production from P. koraiensis seed oil possesses great potential in food healthy field in the future.

“…Some fatty acid alkyl esters, such as FAEEs and FASBEs, consist of a long-chain acyl moiety with a short-chain alkyl moiety, and these esters are suitable for use as biofuel molecules. FAEE is considered as one of the main components of biodiesel, which provides an environmentally attractive alternative to fossil diesel ( Hill et al, 2006 ; Kuan et al, 2019 ); FASBE possesses a methyl branch in the alcohol portion, which affords a lower cloud point than FAEE, thus enabling superior use for energy applications in cold-climates ( Wang et al, 2012 ). Traditionally, bio-esters with the short-chain alkyl moieties mentioned above are industrially produced from plants, animals, or waste cooking oils by transesterification with alcohols ( Leung et al, 2010 ) in the presence of a base, an acid, or an enzyme catalyst.…”

Fatty acid alkyl esters have broad applications in biofuels, lubricant formulas, paints, coatings, and cosmetics. Traditionally, these esters are mostly produced through unsustainable and energy-intensive processes. In contrast, microbial production of esters from renewable and sustainable feedstocks may provide a promising alternative and has attracted widespread attention in recent years. At present, yeasts are used as ideal hosts for producing such esters, due to their availability for high-density fermentation, resistance to phage infection, and tolerance against toxic inhibitors. Here, we summarize recent development on the biosynthesis of alkyl esters, including fatty acid ethyl esters (FAEEs), fatty acid short-branched chain alkyl esters (FASBEs), and wax esters (WEs) by various yeast cell factories. We focus mainly on the enzyme engineering strategies of critical wax ester synthases, and the pathway engineering strategies employed for the biosynthesis of various ester products. The bottlenecks that limit productivity and their potential solutions are also discussed in this review.
