    查看更多>>摘要：? 2022 Elsevier B.V.The sustainable and eco-compatible valorization of renewable feedstocks to synthesize important chemicals is an intense area of research. Currently, ozonolysis is the sole industrial process for the sustainable synthesis of azelaic acid, predominately utilizing oleic acid. Here, the work described the utilization of a non-edible Triadica sebifera seed oil and other vegetable oils to synthesize azelaic acid in 48–72% yields. The process utilized a recyclable WO3-Na2SnO3 based commercial heterogeneous catalytic system and a greener oxidant (30% aq·H2O2), which resulted in a less harmful impact on the environment. The catalytic system was also utilized to synthesize other commercially important dicarboxylic acids, such as succinic acid with 58% yield and suberic acid with 56–60% yields. A non-fatty acid-containing oil (anise oil) was used to synthesize p-anisic acid at the gram scale in a 76% yield. A range of benzoic acid derivatives has also been synthesized by utilizing various substituted styrenes in 52–88% yields.

This study aims to determine the moisture sorption isotherms, fitting mathematical models, and predicting the shelf-life of samples with different mass ratios of powdered hemp flower/leaf at different temperatures. The sorption isotherms of powdered hemp flower to leaf ratios (1:0, 0.75:0.25, 0.5:0.5, 0.25:0.75, 0:1) were determined and shelf-life predicted at different temperatures (20, 30, 40, 50, and 60 °C) using a vapor sorption analyzer; afterward, the adsorption and desorption equilibrium moisture contents (EMC) of different ratios of powdered hemp flower to leaf were modeled using six common empirical models. Both adsorption and desorption EMC of all ratios of powdered hemp flower to leaf decreased as temperature increased. Furthermore, shelf-life of the powdered hemp samples decreases as temperature increases. Modified Halsey and Henderson equations were the best models for the hemp sample isotherms.

    Down-regulating a fiber-specific KCR like gene GhKCRL1 suppressed fiber elongation through blocking the synthesis of sphingolipids in fiber cell

    查看更多>>摘要：? 2022 Elsevier B.V.Cotton is an important natural fiber crop in the world. Cotton fiber cell is an extremely elongated single-cell trichome of seeds. Therefore, the fiber cell is an ideal model for studying plant cell elongation (polar expansion) and secondary wall deposition. Moreover, the two processes determine the quality (length, strength and fineness) of mature cotton fiber. However, the regulatory mechanism of fiber elongation remains unclear. Ligon lintless-1 (Li-1) mutant is a fiber elongation mutant and a good material to study fiber elongation. In the present study, through analyzing the different expression genes in 10-DPA (day post anthesis) fiber cell of Li-1 mutant and its wild type (TM-1), we found a KCR (3-Ketoacyl-Coenzyme A Reductase) like gene, GhKCRL1, was strikingly down-regulated in Li-1 mutant. GhKCRL1 shared low sequence identity with the 17 beta-hydroxysteroid dehydrogenase 12 of animal and the reported GhKCR1, GhKCR2, and GhKCR3 of upland cotton. GhKCRL1 was specifically expressed in fiber cells and its expression level peaked in 10-DPA fiber cells. GhKCRL1 is located in the endoplasmic reticulum. Down-regulating the expression of GhKCRL1 suppressed fiber elongation and significantly shortened mature fiber length. The sphingolipids contained VLCFA and LCFA strikingly declined in RNAi fiber cells. Consistently, the expression levels of most genes involved in sphingolipid biosynthesis and very long chain fatty acid (VLCFA) biosynthesis decreased in GhKCRL1 down-regulated cotton fibers. And the exogenous application of VLCFA (C24 FA) could rescue the elongation of GhKCRL1 down-regulated fiber cells. Taken together, the results revealed that the fiber-specific GhKCRL1 play some roles in cotton fiber elongation by regulating sphingolipid biosynthesis.

    查看更多>>摘要：? 2022 Elsevier B.V.The essential oils (EOs) produced by a number of Apiaceae species are well known for their insecticidal efficacy against a wide spectrum of insects, including vectors, stored product and agricultural pests. In the real world, rawly formulated EOs are scarcely effective due to their low chemical stability, limited persistence into the environment, and poor hydrophilicity. Therefore, for practical applications they need to be encapsulated using nanocarriers. In the present study, we evaluated two novel EO-based nanoemulsions (NEs) derived from Pimpinella anisum and Trachyspermun ammi, two plants with documented insecticidal effectiveness, for the management of stored product insects causing economic damages, including Tribolium castaneum, Tribolium confusum, Tenebrio molitor, Trogoderma granarium adults or larvae, and Acarus siro adults or nymphs. The NEs were prepared by a high-pressure homogenization procedure and determined according to the distribution of particle size through dynamic light scattering. Pimpinella anisum EO resulted mainly dominated by the phenylpropanoid (E)-anethole, while T. ammi EO was mainly composed of thymol, p-cymene, and γ-terpinene. Each EO-based NE was tested at two concentrations (500 and 1000 ppm) on stored wheat. We evaluated mortality values of the arthropod pests after 4 h, 8 h, and 16 h, and daily from 1 to 7 days. Complete mortality was achieved for T. castaneum larvae on wheat sprayed with 1000 ppm of 4% (w/w) P. anisum EO-based NE after 6 days of exposure. Similarly, the 8% (w/w) T. ammi EO-based NE killed 100.0% of the tested T. confusum larvae after 7 days to 1000 ppm. When A. siro adults were exposed to 1000 ppm of the 8% (w/w) T. ammi EO-based NE, 89.4% of the tested individuals were killed after 7 days. Binary EO-based NE combination toxicity tests were also carried out. Almost all T. molitor adults (97.8%) died after 7 days to 1000 ppm of 3% (w/w) T. ammi + 3% (w/w) P. anisum EO-based NE. The 3% (w/w) T. ammi + 3% (w/w) P. anisum EO-based NE killed 98.6% of T. granarium adults after 7 days at 1000 ppm. Overall, the tested Apiaceae EO-based NEs exhibited relevant pesticidal efficacy under short exposure intervals, therefore they could be taken into account as auxiliary management tools towards the sustainable protection of durable commodities in storages.

    Fukuda J.Hsieh Y.-L.

    查看更多>>摘要：? 2022 Elsevier B.V.Cellulose has been efficiently isolated from almond shell (AS) of a soft-shell Carmel variety by a two-step NaClO2 oxidation-KOH alkali protocol at over 35 % yield, then optimally TEMPO-oxidized and blended to yield 92 % and averagely 1.2 nm high (H), 5.2 nm wide (W), and 1.4 μm long (L) cellulose nanofibers (CNFs) with 58.6 % crystallinity and 1.3 mmole/g charge. With uniquely high 1167 L/H aspect ratio and 4.3 W/H lateral anisotropy, AS CNFs self-assembled into 1D fibers and 3D aerogels by freezing at ? 196 °C and ? 20 °C, respectively, then lyophilization as well as 2D films by air drying. All fibers were fully re-dispersable in water to individualized CNFs whereas aerogels were amphiphilic super-absorbents, absorbing slightly more hydrophobic chloroform than water, and films were hydrophilic on the surfaces and absorbed ca. three times more water than decane. The fully aqueous dispersible fibers, amphiphilic and water resilient aerogels, and organic resilient films are attributed to the interfacial associations of AS CNF driven by their uniquely high aspect ratio and cross-sectional anisotropy, demonstrating processing potential into versatile 1D to 3D materials.

    查看更多>>摘要：? 2022 Elsevier B.V.Nitrogen can be critical in determining fiber yield and quality in cotton. Major purpose of this 3-years (2017, 2018, and 2019) study in Faizabad-Iran was to investigate the effect of nitrogen rates, excess on the need for maximum yield and its interaction with environment on fiber quality of bolls with different spatial and temporal distribution in cotton canopy. Field experiment was a split-plot design with four replications. Main plots included two nitrogen rates (LN: 100 and HN: 200 kg ha?1). Sub plots included four boll growth habits: UPER–Upper bolls Early in the season; LOER–Lower bolls Early in the season; UPLA–Upper bolls Late in the season; LOLA–Lower bolls Late in the season. Results showed that fiber yield and fiber quality in terms of fiber uniformity and fiber strength were not affected by experimental factors and their interactions. In all years, LN led to an optimum micronaire (3.5–4.9 μg inch?1) and medium length (25.4–28.6 mm) fibers in all growth habits. However, in 2017, HN combined with lower temperature (25.2 °C) during the boll development decreased LAI to boll number ratio (source restriction), delayed maturity, and shifted fiber yield to UPLA boll growth habit with fine (micronaire < 3.5 μg inch?1) and short length (< 25.4 mm) fibers. In 2018 and 2019 with 1.7 °C and 2.3 °C higher temperatures than 2017, HN increased LAI to boll number ratio (sink restriction), led accelerated maturity, and shifted fiber yield to UPER and LOER boll growth habits, while with the increase of nitrogen, the difference between growth habits in terms of fiber quality was observed only in 2018 that led to production of coarse (micronaire > 4.9 μg inch?1) and long length (> 28.6 mm) fibers in UPER and LOER growth habits. In 2019, the lowest lint yield distribution was observed in UPLA treatment, but the fiber quality parameters were similar in all growth habits. These results may conclude that nitrogen consumption, in excess of what required for maximum yield, affects the source-sink relationship and leads to the formation of bolls with different fiber quality within a canopy, and the response of these processes to nitrogen is affected by the environment.

    查看更多>>摘要：? 2022 Elsevier B.V.In this study, extract from Manihot esculenta was evaluated as an ecofriendly coagulant for treating turbid wastewater. Chemical and morphological characterization of the coagulant was performed using field emission scanning electron microscopy (FESEM) with energy dispersive spectroscopy (EDS) and Fourier transform infrared (FTIR) spectroscopy. The coagulation jar tests were done on the basis of a central composite rotatable design (CCRD), while parametric modeling and optimization of the process was done via the statistically inclined response surface methodology (RSM) and the neural intelligence tool (artificial neural networks (ANN). From the FTIR spectra, the coagulant was shown to be characterized by diverse functional groups that have been reported to have a synergistic effect on coagulation. The morphological characteristics obtained from FESEM showed a porous structure. The compositional analysis obtained with EDS showed that the major constituents were carbon and oxygen, which accounted for 67.8% and 23.9%, respectively. Other elements present in the coagulants were potassium (4.6 %), bromine (1.2 %), calcium (1.2 %), phosphorus (0.7 %), magnesium (0.4 %) and silicon (0.3 %). RSM and ANN showed adequacy in modeling the process, although ANN clearly outperformed RSM with better goodness of fit statistical indicators. RSM and ANN both predicted similar maximum turbidity removal (95.4 % and 96.7 %, respectively) under optimized conditions. Thus, Manihot esculenta leaf extract could serve as an efficient coagulant for the remediation of turbid wastewater.

    Flavonoid-rich extract of Toxicodendron vernicifluum served as a natural neuroprotective agent

    Li M.Zhang Y.Meng C.Gao J....

    查看更多>>摘要：? 2022 Elsevier B.V.Lacquer tree [Toxicodendron vernicifluum (Stokes) F. A. Barkley Stokes], an economically important tree species that contains flavonoids as its major biologically active constituents, is mainly used to produce raw lacquers. Due to its sizeable production, the accumulation of byproducts is extensive, especially of older trees that cannot produce raw lacquers. It is considerable to develop new applications for these waste materials. Herein, a flavonoid-rich extract from the heartwood of T. vernicifluum (FRET) was prepared, and its potent in vitro neuroprotective properties against H2O2-induced oxidative injury in SH-SY5Y cells were demonstrated for the first time. The main components of FRET were determined by UF-HPLC-QTOF/MS, and the underlying mechanism of the neuroprotective effect was revealed. The results showed that FRET pretreatment significantly attenuated H2O2-induced cell apoptosis in a dose-dependent manner by lowering ROS production and increasing the mitochondrial membrane potential. Mechanistically, the neuroprotective effects of FRET were confirmed to be associated with Nrf2/HO-1, PI3K/Akt/mTOR-GSK3β, IL-6/Src-Stat3 and MAPK pathways. This study suggested that FRET with promising neuroprotective properties might be developed as a functional food or potential drug candidate for the prevention or treatment of diseases caused by oxidative stress and also provided a novel strategy for the comprehensive utilization of T. vernicifluum.

    Micro and nanocellulose extracted from energy crops as reinforcement agents in chitosan films

    Pires J.R.A.Souza V.G.L.Gomes L.A.Fernando A.L....

    查看更多>>摘要：? 2022 Elsevier B.V.The quest for more renewable and biodegradable materials currently represents a scientific key focus to combat the massive maneuver of non-sustainable products. Lignocellulosic feedstocks are rich in cellulose, hemicellulose, and lignin which, when recovered and separated, can give rise to innovative value-added products. Cellulose at the micro (MCC) and nanosized crystalline particles (CNC) are suitable examples of bioproducts that provide applications in many distinctive areas. The insertion of these homogeneously scattered particles, as a reinforcement agent, into the chitosan (Ch) films, is seen as a promising possibility to surpass the shortcomings associated with bioplastics. Therefore, the aim of this work was to test a combination of MCC and CNC obtained from biomass from giant reed (Arundo donax L.), kenaf (Hibiscus cannabinus L.) and, miscanthus (Miscanthus × giganteus Greef et Deu.) as reinforcement agents in Ch films. Extraction of MCC and CNC was carried out via an alkaline pre-treatment approach followed by acid hydrolysis. The particles were incorporated in Ch at different rates (1.5 %, 2 %, and 2.5 % w/w of chitosan), and the resultant biocomposites were fully characterized in terms of their morphology, mechanical and optical properties, permeability (oxygen and water vapor), water wettability, thermal analysis, X-ray diffraction, and FT-IR. Chitosan films reinforced with commercial nanocellulose at the same rates were tested for comparison. It was observed an improvement for the majority of samples after the incorporation of MCC/CNC, as planned. The sample with MCC/CNC isolated from giant reed was the one that most improved the properties of the film. Between the amounts added, the 2.5 % level presented the most encouraging effects, by improving considerably the strength and stiffness and by reducing the oxygen and water vapor permeabilities, essential features in the use of bio-based films by e.g. the food packaging industry. For this MCC/CNC rate, the films demonstrated equivalent potential to the film with 2 % commercial CNC. Predominantly, the different analyses displayed in the study indicated that biomass from the three lignocellulosic crops tested may afford a viable alternative source of reinforcing agents to be applied in the biocomposites production.
