Pecan and hickory nuts are two of consumers favorite ones. Pecan seeds can be eaten fresh, while hickory ones must remove astringency before eating. Here, we reported that total phenols, flavonoids and condensed tannins of hickory seeds were reduced after de-astringent treatments. They gradually increased with development, showing higher levels in hickory seed coat at mid-late periods than that in pecans. Widely-targeted metabonomics anal. of developing testa identified 424 kinds of components, including 101, 38, 58, 27 classes of flavonoids, tannins, phenolic acids, organic acids and others, showing 16 different changing trends. Notably, most kinds of flavonoids, hydrolysable tannins and phenolic acids at maturity were more than that of pecans, while oligomeric condensed tannins were opposite. Gene expression anal. provided further explanations for their dynamic accumulation. These results unraveled potential astringent components in hickory testa and preliminary mol. mechanisms of their dynamic changes, offering theor. basis for the targeted de-astringency.

Smit, Arjan T. published the artcileLaboratory- to Pilot-Scale Fractionation of Lignocellulosic Biomass Using an Acetone Organosolv Process, Recommanded Product: 4-Hydroxy-3,5-dimethoxybenzaldehyde, the publication is ACS Sustainable Chemistry & Engineering (2022), 10(32), 10503-10513, database is CAplus.

Acetone organosolv fractionation of beech and birch wood at laboratory-scale results in high sugar yields from the (hemi)cellulose and the isolation of a high purity lignin. In this study, the process is scaled up to validate the technol. at pilot-scale using industrial size beech and birch wood chips and low liquid-to-solid ratios as a next step toward commercialization. Translation of the fractionation process to pilot-scale showed similar performance as compared to the laboratory-scale processing with a good conversion of the wood polymeric pentoses to mostly monomeric sugars and a high delignification. Continuous lignin precipitation by solvent evaporation using the LigniSep process resulted in the formation of nonsticky lignin aggregates with a good filterability. The improved lignin yields and advanced process design as compared to the traditional dilutive lignin precipitation approaches are likely to translate to a better process economy. The pulp washing efficiency and the recovery of (nonprecipitable) lignin from the aqueous hemicellulose stream needs still to be improved for an efficient process design. However, the fractionation performance and high product concentrations in the spent liquor provide an excellent start position for improved process design at com. scale.

Sumer, Zeynep published the artcileData-Centric Development of Lignin Structure-Solubility Relationships in Deep Eutectic Solvents Using Molecular Simulations, Application of 4-Hydroxy-3,5-dimethoxybenzaldehyde, the publication is ACS Sustainable Chemistry & Engineering (2022), 10(31), 10144-10156, database is CAplus.

Lignin is a natural source of aromatic chems. with significant potential as an abundant, renewable feedstock for value-added products. Deep eutectic solvents (DES)-solvents composed of a hydrogen bond donor (HBD) and acceptor (HBA) in varying ratios-have emerged as a highly tunable class of solvents for lignin solubilization. However, the variety of possible DES compositions and limited mol.-scale understanding of lignin solubility makes solvent selection a challenge without laborious trial-and-error experimentation. To address these challenges, we use classical mol. dynamics (MD) simulations to study the interactions of lignin model compounds with various DES-water systems. Quant. parameters (descriptors) were calculated by postprocessing the MD results and used to train a regression model that predicts exptl. determined solubilities of lignin model compounds This approach revealed that the most important descriptors of solubility are the system temperature, solute hydrophilicity, and metrics quantifying hydrogen bonding. Maximizing the interactions between solute-HBD (hydrophobic group), water-HBD (hydrophilic group), and water-HBA mols. led to the highest model compound solubility Our results support a hydrotropic mechanism in which extensive DES-water hydrogen bonding and favorable HBD interactions with the solute promote high solubility We applied the regression model derived using model compounds to predict the solubility of representative lignin oligomers. The model predicted lignin oligomers’ solubilities in good agreement with experiments, indicating that the simulations of model compounds can be extended to predict the solubility of larger lignin compounds across a range of solvent compositions and temperatures These findings provide new mol.-scale insight into lignin solubilization mechanisms and a new method for computationally screening potential solvent systems for lignin valorization.

Cuprys, Agnieszka published the artcilePotential of agro-industrial produced laccase to remove ciprofloxacin, Synthetic Route of 134-96-3, the publication is Environmental Science and Pollution Research (2022), 29(7), 10112-10121, database is CAplus and MEDLINE.

Ciprofloxacin (CIP), a widely used antibiotic, is frequently detected in the environment due to insufficient wastewater and water treatment. Hence, novel, green and cost-effective technologies are required to enhance the removal of these pollutants. The potency of crude enzymes, especially laccases, produced by white-rot fungi was tested to assess their effectiveness to degrade CIP from water. Crude laccase alone could not oxidize CIP. The addition of syringaldehyde, a redox mediator, resulted in a decrease in antibiotic concentration up to 68.09±0.12% in 24 h, which was the highest removal efficiency achieved with 0.15 mg/mL syringaldehyde and 2 mg/mL of crude laccase (0.1 U/mL). Crude laccase oxidation of CIP was inhibited after 6 h of treatment. To compare, a pure enzyme with the same activity as the crude one removed 86% of CIP in 24 h. No inhibitory effect during the treatment was observed The estimation of antimicrobial efficiency revealed that after 6 h of treatment, the toxicity towards Escherichia coli decreased by 30%. The wastewater treatment by the crude laccase-mediated system was estimated to significantly reduce the cost of enzymic treatment.

Saini, Bhavna published the artcileNickel nano-particles confined in ZSM-5 framework as an efficient catalyst for selective hydrodeoxygenation of lignin-derived monomers, Category: ethers-buliding-blocks, the publication is Biomass and Bioenergy (2022), 106350, database is CAplus.

The present study offers an efficient, economical, non-noble metal based catalytic process for the selective HDO of lignin-derived compounds HDO of major lignin constituting monomers like vanillin, syringaldehyde, guaiacol, and cresol were studied over Ni(2.5)@ZSM-5 catalysts. Complete conversion of vanillin and syringaldehyde was achieved with >99% selectivity towards creosol and 4-methylsyringol resp., while the reactions with guaiacol and cresol did not show any conversion. The catalyst is highly selective towards the conversion of the aldehydic group to Me group. Potential of the catalyst to be used at more realistic conditions was ascertained by evaluating the catalyst with simulated feed prepared by mixing lignin monomers and impurities like S, Na, and K. The catalyst showed excellent results with simulated feed similar to the pure model compounds Various characterization techniques like XRD, FTIR, NH3-TPD, H₂-TPR, UV-DRS, TEM, TGA, etc. were employed to understand the physico-chem. properties of the catalytic material. The nature and location of Ni species in the catalyst were determined as well as the most plausible active center for the HDO reaction was identified. The study revealed that active metal and acid site in close proximity exhibits a synergistic effect which leads to superior catalytic activity. Effect of support acidity was studied in more detail by evaluating the catalysts with variable acidity. The meritorious properties of the catalyst like exceptionally high selectivity, good stability, tolerance for impurities, excellent recyclability as well as economical catalyst formulation make it suitable to be used for the processing of real feeds at realistic conditions.

The present study evaluated the potential of biodegrading the toxic synthetic dye malachite green (MG) by an enzymic approach. Extracellular laccase derived a fungal strain Fusarium oxysporum HUIB02 was used in the direct biodegradation of MG. Time-course study showed that the crude laccase successfully removed ≥ 80% MG after 20 h of treatment. The presence of Cu²⁺ ions enhanced MG degradation, while cation Fe²⁺ and anions including Cl^– and I^– reduced the degradation efficiency. The optimal temperature was 40°C. Supplementation of mediators including syringaldehyde (SA), 1-hydroxybenzotriazole (HBT), and vanillin (VA) improved the MG degradation up to 99%. Under the optimal reaction conditions, the MG degradation efficiency of laccase reached ≥ 90% when MG concentration was ≤ 100 mg/L. At a higher concentration (1000 mg/L of MG), the enzyme still removed 88.1% the present dye. The detoxification evaluation confirmed the nullification of MG toxicity on microorganism after the enzymic treatment. Hence, this enzymic degradation approach is promising for the treatment of effluents containing MG.

Vorobyova, Viktoria published the artcileA New Combination Inhibitor Based on Tomato Pomace Extract and Organosilane for Enhanced Anticorrosion Performance of Steel, Product Details of C9H10O4, the publication is Chemistry Africa (2022), 5(4), 997-1014, database is CAplus.

The study aims to assess the effect of extract based inhibiting mixture, i.e., tomato pomace and organosilanes (Vinyltrimethoxysilane (VS)) against corrosion of steel in atm. environment. Such compositions can be used as polymer-type corrosion inhibitors for steel. The developed blend VCI based on tomato pomace extract (TPE) and organosilane provide a long-term protection from corrosion processes under the model conditions of carbon steel. The results show that the protection efficiency of the film reaches 96.97%. The tomato pomace extract chem. composition was analyzed by Head Space-Solid Phase Micro Extraction-Gas Chromatog.-Mass Spectrometry (HS-SPME-GC-MS). The major volatile compounds ot the TPE include alcs., esters, aldehydes, ketones and terpene compounds as described by panelists of HS-SPME-GC-MS. Electrochem. studies reveal decreased corrosion current densities from 4.29 x 10-4 to 0.65 x 10-4 A cm^-2 and increased polarization resistance under the conditions of periodic moisture condensation. FT-IR absorption peak obtained at 954, 1142, 1230 cm^-1 revealed the formation of Fe-O-Si, Si-O-Si and Si-O-C bonds. The protective film consesed of silane and extract offered the highest corrosion resistance since the corrosion protective barrier minimized the oxygen access and prevented corrosion of mild steel to a greater extent where the EDX anal. showed a high intense signal of Si and C. The mixture of phytochem. extract and organosilane were incorporated in a paint coating. The addition of additive increases the inhibitory properties of the final coating while keeping the barrier properties of the coating.

Vorobyova, Victoria published the artcilePotential of Tomato Pomace Extract as a Multifunction Inhibitor Corrosion of Mild Steel, Application In Synthesis of 134-96-3, the publication is Waste and Biomass Valorization (2022), 13(7), 3309-3333, database is CAplus.

The aim of this paper is to investigate tomato pomace extract (TPE) as a multifunctional ‘green’ vapor phase corrosion inhibitor for prevention from the atm. corrosion of mild steel and as a corrosion inhibitor in neutral media of 0.5 M NaCl solution TPE would be an effective inhibitor with the efficiency of around 98% in both corrosive conditions. The chem. profile of the TPE was analyzed using gas chromatog. mass spectrometry (GC-MS) and high-performance liquid chromatog. anal. (HPLC-DAD-MS). The major volatile constituents identified in tomato pomace extract were alcs. (12.5%), fatty acids (23.78%), aldehydes (41.6%), ketones (8.65%), and terpenoids (9.11%). The predominant semi-volatile and high mol. weight chem. components in tomato pomace extract were phenolic acids and flavanols [caffeic acid (2.03 0.3μg/g), chlorogenic acid (37.23 ± 0.80μg/g), gallic acid (10.2 ±0.80μg/g)]. The corrosion protection properties of the TPE as multifunctional corrosion inhibitor were studied using accelerated corrosion tests (weight loss method) and electrochem. methods [polarization curves and linear polarization technique (LPR)]. The mechanism of steel inhibition by TPE formulations was studied with the help of SEM (SEM) and at. force microscopy (AFM) observations. TPE acts as a “pro-inhibitor” of the steel corrosion in neutral solution The anal. confirmed that the growth of inhibitory properties is prolonged and corrosion rate is reduced after 40-48 h of exposure. The inhibition efficiency increases with increasing exposure time and reaches 98% after 48 h. Quantum-chem. calculations were used to predict the adsorption/inhibition properties of some of the main compounds of the extract and compounds formed as a result of chem. conversion. This work to contributes interpretation/explanation and understanding of the mechanism of action of green corrosion inhibitors in neutral solution
