“…Although mineral-based materials are cheap, they are non-renewable and toxic to the environment. On the other hand, bio-based materials are degradable, non-polluting, non-toxic, and eco-friendly, offering suitable alternatives to fossil sources. , Therefore, the development of economically feasible technologies to produce bio-based products such as biolubricants from renewable sources has been accelerated in recent years. − …”

The chemical structure of a biolubricant plays an important role to determine its physicochemical and tribological properties. In this study, five triesters such as trimethylolpropanetriisostearate (T-IS), trimethylolpropane-triisooleate (T-IO), trimethylolpropane-trioleate (T-OA), glycerol-triisooleate (G-IO), and glycerol-trioleate (G-OA) have been synthesized via esterification of glycerol/trimethylolpropane with the respective free fatty acids (FFAs). FFAs such as methyl-branched isostearic and isooleic acids used for these T-IS, T-IO, and G-IO triester's synthesis were previously made via skeletal isomerization of naturally derived oleic acid using a reusable zeolite catalyst. After esterification, any extra unreacted FFAs were recycled for the subsequent batch synthesis, resulting in little to no waste being produced. The chemical structures of the synthesized triesters have been determined with nuclear magnetic resonance, liquid chromatography-mass spectroscopy, Fourier transform infrared, and gas chromatography-mass spectroscopy. The physicochemical and tribological properties of these triesters have been compared to each other, and with that of high-oleic sunflower oil and polyalphaolefin, common lubricant base oils to demonstrate how the differences in molecular structure can influence their properties. Lubricant property analysis reveals that all the five synthesized triesters have the potential to be used as biolubricants. Practical application: modification in the chemical structure of natural lipids is found useful to improve their physicochemical and tribological properties and thus can be potentially used as biolubricants.

As one of the sources of biodiesel, microalgae are expected to solve petroleum shortage. In this study, different concentrations of piperonyl butoxide were added to the culture medium to investigate their effects on the growth, pigment content, lipid accumulation, and content of carotenoids in Dunaliella tertiolecta. The results showed that piperonyl butoxide addition significantly decreased the biomass, chlorophyll content, and total carotenoid content but hugely increased the lipid accumulation. With the treatment of 150 ppm piperonyl butoxide combined with 8000 Lux light intensity, the final lipid accumulation and single-cell lipid content were further increased by 21.79 and 76.42% compared to those of the control, respectively. The lipid accumulation in D. tertiolecta is probably related to the increased expression of DtMFPα in D. tertiolecta under the action of piperonyl butoxide. The phylogenetic trees of D. tertiolecta and other oil-rich plants were constructed by multiple sequence alignment of DtMFPα, demonstrating their evolutionary relationship, and the tertiary structure of DtMFPα was predicted. In conclusion, piperonyl butoxide has a significant effect on lipid accumulation in D. tertiolecta, which provides valuable insights into chemical inducers to enhance biodiesel production in microalgae to solve the problem of diesel shortage.
