“…Lipases (triacylglycerol ester hydrolase, EC 3.1.1.3) are a kind of enzymatic biocatalyst. Lipases can be extracted from several origins like fungi, bacteria, and yeast and can be used commonly in hydrolysis, esterification/cyclo-esterification, and transesterification reactions because of their excellent chemo-, region-, and stereoscopic selective properties [ 14 , 92 , 93 ]. Each lipase has different specificity toward its reactants, both Gly/vegetable oil (triglyceride) and DMC.…”

High energy demand driven by decreasing fossil fuels, and global warming because of the burning of fossil fuels necessitates the utilization of renewable and clean energy. One of these renewable energy sources is biodiesel. The increasing trend of biodiesel over the last 20 years tends to result in increasing glycerol (Gly), which is produced during the biodiesel production in 10% ratio (w/w) as a by-product. Using Gly as raw material is an alternative way to produce bio-based new products such as glycerol carbonate (GlyC). GlyC is a value-added product of Gly/vegetable oil and this product can be used as a potential fuel additive in the future because of its high oxygen content. Furthermore, GlyC shows a high reactivity; therefore, it is a bio-based building block for complex chemicals. The present review gives information about the bio-catalytic synthesis of GlyC from Gly/vegetable oil and, dimethyl carbonate (DMC). In addition, the influencing parameters of this bio-catalytic GlyC synthesis are discussed and reviewed in this paper.

“…On the topic of waste management and circular economy, Unugul et al, 194 recently researched the production of biolubricants from coffee wastes where oils were extracted. By enzymatic hydrolysis (ie, using Lipozyme TL IM [ Thermomyces lanuginosus ]) and enzymatic esterification (ie, using Novozyme 435 [ Candida antarctica ]) of the free fatty acids with TMP, the transesterified biolubricants depicts around 88% FFA conversion at optimal conditions of 5% enzyme loading (w/w), non‐aqueous media, FFA/TMP mole ratio (3:1), 24 hours, and a reaction mixing speed of 500 rpm.…”

Summary The growing concern and limitations for existing lubricants have driven the need for biolubricants, extensively proposed as the most suitable and sustainable lubricating oils. Biolubricants are generally synthesized from various bio‐based sources, including vegetable oils, microbially derived oils, waste cooking oil, etc. They are promising commodities and advantageous to mineral‐based analogues due to their exceptional properties like their lubricity, biodegradability, reduced toxicity, and reduced volatility. Yet, their utilization as lubricants is constrained due to their relatively poor cold‐flow and thermo‐oxidative stability uncertainties even after being chemically modified. Hence, many chemical modification pathways have been reported to overcome this limitation, with the most exploited approaches being esterification and transesterification. This modification pathway enhanced the thermo‐oxidative stability and the cold‐flow properties of these bio‐based oils, increased the yield, and enhanced the quality of the lubricants. With this in mind, this paper reviews up‐to‐date works conducted in this area and critically report the advancement in esterification and transesterification production of biolubricants. The study further reviews the latest published literature, current updates, and future perspectives related to the synthesis of biolubricants. Also, the review highlights the significant factors that govern the entire reaction process, selection criteria of renewable feedstocks, and the tribological performance of biolubricants.

Lignocellulosic biomasses are used in several applications, such as energy production, materials, and biofuels. These applications result in increased consumption and waste generation of these materials. However, alternative uses are being developed to solve the problem of waste generated in the industry. Thus, research is carried out to ensure the use of these biomasses as enzymatic support. These surveys can be accompanied using the advanced bibliometric analysis tool that can help determine the biomasses used and other perspectives on the subject. With this, the present work aims to carry out an advanced bibliometric analysis approaching the main studies related to the use of lignocellulosic biomass as an enzymatic support. This study will be carried out by highlighting the main countries/regions that carry out productions, research areas that involve the theme, and future trends in these areas. It was observed that there is a cooperation between China, USA, and India, where China holds 28.07% of publications in this area, being the country with the greatest impact in the area. Finally, it is possible to define that the use of these new supports is a trend in the field of biotechnology.
