“…Inspired by the above, scholars have made attempts by using biolubricant in minimum quantity lubrication (MQL) for sustainable manufacturing. Triglycerols of fatty acids are the main ingredients of vegetable oils and animal fats, which usually has poor extreme pressure properties [6]. Especially, biolubricant couldn't meet anti-friction and heat-transfer requirements of machining, in which working zone characterized by high-temperature and high-pressure.…”

To eliminate the negative effect of traditional metal-working fluids and achieve sustainable manufacturing, the usage of nano-enhanced biolubricant (NEBL) is widely researched in minimum quantify lubrication (MQL) machining. It’s improved tool wear and surface integrity have been preliminarily verified by experimental studies. The previous review papers also concluded the major influencing factors of processability including nano-enhancer and lubricant types, NEBL concentration, micro droplet size, and so on. Nevertheless, the complex action of NEBL, from preparation, atomization, infiltration to heat transfer and anti-friction, is indistinct which limits preparation of process specifications and popularity in factories. Especially in the complex machining process, in-depth understanding is difficult and meaningful. To fill this gap, this paper concentrates on the comprehensive quantitative assessment of processability based on tribological, thermal, and machined surface quality aspects for NEBL application in turning, milling, and grinding. Then it attempts to answer mechanisms systematically considering multi-factor influence of molecular structure, physicochemical properties, concentration, and dispersion. Firstly, this paper reveals advanced lubrication and heat transfer mechanisms of NEBL by quantitative comparison with biolubricant-based MQL machining. Secondly, the distinctive filmformation, atomization, and infiltration mechanisms of NEBL, as distinguished from metal-working fluid, are clarified combining with its unique molecular structure and physical properties. Furtherly, the process optimization strategy is concluded based on the synergistic relationship analysis among process variables, physicochemical properties, machining mechanisms, and performance of NEBL. Finally, the future development directions are put forward aiming at current performance limitations of NEBL, which requires improvement on preparation and jet methods respects. This paper will help scientists deeply understand effective mechanism, formulate process specifications, and find future development trend of this technology.

Lauric Acid from the Black Soldier Fly (Hermetia illucens) and Its Potential Applications

Black soldier fly (BSF) (Hermetia illucens) larvae are currently being developed as bioconversion agents for organic waste treatment. The resulting larvae or prepupae have a high protein and lipid content, primarily used as feed for fish, poultry, and other animals. The lipid content of BSF larvae/prepupae is influenced by the feed for growth and can reach up to 57.8%. BSF lipids mainly consist of medium-chain saturated fatty acids, with lauric acid (LA) being the dominant component. The LA content in BSF larvae/prepupae can be enhanced by incorporating or utilizing substrates containing highly digestible carbohydrates for larval growth. The LA content can reach 76.13% in larvae reared on fruit waste. LA has been reported to exhibit antibacterial, antifungal, antiviral, and anticancer properties. Moreover, it has applications in various fields such as pharmaceuticals, food and beverages, cosmetics, body care, soaps and detergents, plastics, and textiles. This review aims to investigate the LA content in BSF larvae and explore its potential applications, thereby establishing BSF larvae/prepupae as a novel source of LA for diverse fields.

“…Great potentials are held in BSF for its nutritional value. For the inside grease, after extraction, separation, and refinement, could be added into feed (Fawole et al, 2021; Heuel et al, 2021) or cosmetic products (Almeida et al, 2020) as gradients, depending on the depth of refinement, or as raw materials for biodiesel (Zheng et al, 2012; Nguyen et al, 2017; Wang et al, 2017) and biolubricants (Xiong et al, 2020) after transesterification. BSF, as a nova resource insect, is worthy of conducting research on functions of perilipins in lipid homeostasis to maximize its advantages for application.…”

As intracellular organelles in adipose tissue, lipids droplets manage the balance between triglyceride accumulation and energy consumption in animals. Perilipin family members, associated with surface of lipid droplets, participate the regulation of lipid metabolism. Lipid storage droplet-1 (LSD1)/Perilipin-1 acts as a gatekeeper for adipose lipid storage in animals. Despite extensive studies in fruit fly, the function of LSD1 in insect larval stage remain indistinct. In this study, we characterized the function of LSD1 in black soldier fly Hermetia illucens, a nova resource insect to recycle organic wastes. We found that LSD1 was broadly present in dipteran species and evolved with divergence between mosquitos and flies. We further constructed in vivo mutagenesis mediated by CRISPR/Cas9 and found that mutations in LSD1 increased the larval weight and did not bring any defects in development. Raw fat content was also not significantly influenced in late larval stage and new-emerged adults. Our results not only extend our knowledge of LSD1 in insects, but also help for better understanding of the lipid homeostasis in BSF.
