“…Pomegranate ( Punica granatum ) derived punicic acid (PuA; 18: 3Δ 9 cis ,11 trans ,13 cis ) is a typical conjugated fatty acid and a representative plant-derived UFA (Paul and Radhakrishnan, 2020). The three conjugated double bonds in PuA offer a wide range of health benefits, as well as potential applications in the oleochemical industry (Holic et al, 2018; Shockey et al, 2016). Given the emerging applications of PuA in the nutraceutical and chemical industries, its potential market is expected to experience significant growth in the coming years (Holic et al, 2018; Paul and Radhakrishnan, 2020).…”

Producing high-value plant-derived unusual fatty acids in microorganisms via synthetic biology is attractive, but increasing their contents through rational step-by-step gene stacking is challenging. UsingSaccharomyces cerevisiaeand pomegranate-derived punicic acid (PuA) as representatives, an efficient, result-driven gene shuffling strategy was developed to facilitate the production of value-added plant lipids. By targeting yeast Ty retrotransposon regions, candidate genes related to PuA production were directly shuffled within the yeast genome to create recombinant libraries. Subsequent screening and bioprocess optimization led to a recombinant yeast strain with 26.7% of total fatty acids as PuA through neosynthesis. Further analyses revealed that the strain hosts multiple genes, contains over 22% PuA in the storage lipid triacylglycerol, and has substantial changes in its lipidome. Overall, this work provided an efficient strategy for improving PuA content in yeast, which could be adopted to engineer microorganisms for the production of other high-value plant-derived fatty acids and bioproducts.

“…In terms of its drying time, tung oil dries faster compared with other plant oils with similar iodine values, such as linseed and perilla seed oils. This characteristic makes tung oil a preferred choice as a high-quality and highspeed drying oil in the production of paint, varnish, and ink (Shockey et al, 2016;Humar and Lesar, 2013).…”

The aim of the conducted study was to develop wood-polymer composites (WPCs) using secondary polymer waste and agricultural technology waste materials, which would have lower environmental impacts than WPCs made from virgin resources. The study focused on developing WPCs based on polypropylene filled with finely dispersed powders of waste products from tung oil production (PP+TOPW composites). Finely scattered powder (with an average grain size of 0.5–1.5 mm) was obtained from crushing and grinding the outer pericarp of tung fruit waste, which resulted from tung oil extraction. Tung oil is produced in Georgia from tung fruit that is grown in Tsalenjikha district, Georgia. In addition, to modify the properties of the WPCs, organic silicon oligomer tetraethoxysilane and powdered aluminum hydroxide were used as additives. The study found that the strength properties of the PP+TOPW composites can be optimized by modifying them with tung oil and other mineral additives. The optimal strength properties were observed at a filler content of 40 wt.%, where the compression and bending strength limits were 63.5 and 36.7 MPa, respectively. The water absorption of the PP+TOPW composites was reduced by modifying them with tung oil. The PP+TOPW composites with a filler content of 30 wt.% showed 0% water absorption, and the water absorption of composites with a filler content of 40 and 50 wt.% (modified with tung oil) was very low, ranging from 0.2–0.8%. The study also investigated the effect of modifying PP+TOPW composites with tetraethyl orthosilicate (TEOS), which increased all the strength parameters, including impact strength, and reduced water absorption, although not as much as when modified with tung oil. The introduction of a flame retardant, aluminum hydroxide, into the composite composition in the amount of 25–30 wt.% made the composites flame-retardant and low-combustible materials, expanding their potential applications, particularly in construction. Overall, the study successfully developed WPCs using waste materials with optimized properties, which have potential for various applications, including in construction, due to their flame retardant and low-combustible properties.

“…As the name suggests, the trees have been cultivated for oil production for thousands of years in China [ 1 ]. The global Tung oil market was valued at USD 287 million in 2019 and it is expected to reach USD 344.2 million by the end of 2026, growing at a CAGR of 2.6% during 2021–2026 [ 2 , 3 ].…”

“…Thus, tung oil has a faster drying time compared to other plant oils of similar iodine value, such as linseed and perilla seed oil. Because of its fast drying time, it is used as a high-quality and high-speed drying oil in the production of paint, varnish, and ink [ 3 , 4 ]. However, over the past few decades, the use of drying oils has declined due to being replaced by alkyd resins and other binders [ 5 ].…”

Polyhydroxyalkanoates (PHAs) are attractive new bioplastics for the replacement of plastics derived from fossil fuels. With their biodegradable properties, they have also recently been applied to the medical field. As poly(3-hydroxybutyrate) produced by wild-type Ralstonia eutropha has limitations with regard to its physical properties, it is advantageous to synthesize co- or terpolymers with medium-chain-length monomers. In this study, tung oil, which has antioxidant activity due to its 80% α-eleostearic acid content, was used as a carbon source and terpolymer P(53 mol% 3-hydroxybytyrate-co-2 mol% 3-hydroxyvalerate-co-45 mol% 3-hydroxyhexanoate) with a high proportion of 3-hydroxyhexanoate was produced in R. eutropha Re2133/pCB81. To avail the benefits of α-eleostearic acid in the tung oil-based medium, we performed partial harvesting of PHA by using a mild water wash to recover PHA and residual tung oil on the PHA film. This resulted in a film coated with residual tung oil, showing antioxidant activity. Here, we report the first application of tung oil as a substrate for PHA production, introducing a high proportion of hydroxyhexanoate monomer into the terpolymer. Additionally, the residual tung oil was used as an antioxidant coating, resulting in the production of bioactive PHA, expanding the applicability to the medical field.
