Agriculture will increasingly face in coming years numerous challenges, such as climate change, the growing global demand for food, its environmental impact due to greenhouse gas emissions, release of pollutants into environment, and production significant amounts waste. This study focused on pomace, a waste olive pressing, it contains substances that can be valorized. Specifically, this aimed obtain lignin nanoparticles (LNPs) by treating biomass with an ionic liquid (IL) composed triethylamine sulfuric acid [Et3NH][HSO4], having different concentrations water (IL_95, IL_90 IL_80). The LNPs obtained were characterized Fourier Infrared Spectroscopy (FT-IR), Field Emission Scanning Electron Microscopy (FE-SEM), Thermogravimetric (TGA) analysis. 95/5 IL/water ratio allowed obtaining best regarding purity, yields morphology, which further investigating Zeta Potential (ξ) Energy Dispersive x-ray (EDX). from IL_95 applied maize plants at 25, 50 200 mg L−1. Improvements growth, physiological biochemical traits ascertained treated samples. generally induced photosynthetic activity, stomatal conductance reduced cellular CO2 concentration. In addition, improvements production, root morphology pigment content ascertained. Finally, redox state showed lower dosages did not cause oxidative perturbations; instead, they had ameliorative effects. conclusion, opens new way valorize oil pomace nano-scaled lignin, sustainable biobased material interesting biostimulant action.

We report an efficient sustainable two-step anion exchange synthetic procedure for the preparation of choline API ionic liquids (Cho-API-ILs) that contain active pharmaceutical ingredients (APIs) as anions combined with choline-based cations. have evaluated in vitro cytotoxicity synthesized compounds using three different cells lines, namely, HEK293 (normal kidney cell line), SW480, and HCT 116 (colon carcinoma cells). The solubility APIs Cho-API-ILs was water/buffer solutions found higher Cho-API-ILs. Further, we investigated antimicrobial potential pure APIs, ILs, against clinically relevant microorganisms, results demonstrated promise potent agents to treat bacterial infections. Moreover, aggregation adsorption properties were observed by a surface tension technique. behavior these further supported conductivity pyrene probe fluorescence. thermodynamics has been assessed from temperature dependence tension. micellar size their stability studied dynamic light scattering, transmission electron microscopy, zeta potential. Therefore, duality nature explored upgradation physical, chemical, biopharmaceutical properties, which enhance opportunities advances sciences.

Deep Eutectic Solvent-Extracted Lignin as an Efficient Additive for Entirely Biobased Polylactic Acid Composites

ACS Applied Polymer Materials, Год журнала: 2022, Номер 4(8), С. 5861 - 5871

Опубликована: Июль 1, 2022

This work reports the fabrication and characterization of entirely biobased composites made with polylactic acid (PLA) deep eutectic solvent (DES)-extracted lignin. White fir sawdust corn stover were used as feedstocks to extract lignin (SDL) (CSL). Commercial alkali (CAL) was also a baseline. PLA/lignin fabricated using twin-screw extrusion process followed by compression molding. Characterizations conducted scanning electron microscopy (SEM), thermogravimetric analysis (TGA), differential calorimetry (DSC), tensile testing. Overall, results revealed that PLA/DES biocomposites significantly outperform their PLA/CAL counterparts. SEM indicated absence microcracks in morphologies better dispersion smaller agglomerates compared composites. The initial thermal degradation temperature PLA slightly dropped 8–27 °C addition 5–15 wt % DES lignin, significant reduction 89–124 when incorporating CAL. DSC showed maximum drop about 5 15 melt CAL respectively, added. Moreover, SDL increased PLA's crystallinity several folds. strength elongation at break greater than those composites, up 1 order magnitude. performance associated high purity, ultrafine particle size, low heterogeneity, molecular weight suggest potential feedstock for high-performance materials.

The growing need to expand the use of renewable energy sources in a sustainable manner, providing greater supply security and reducing environmental impacts associated with fossil fuels, finds agricultural by-product bioethanol an economically viable alternative significant expansion potential. In this regard, dramatic boost efficiency processes already place is required, costs, industrial waste, our carbon footprint. Biofuels are one most promising alternatives massively produce sustainably short-term period. Lignocellulosic biomass (LCB) highly recalcitrant, effective pretreatment strategy should also minimize carbohydrate degradation by diminishing enzyme inhibitors other products that toxic fermenting microorganisms. Ionic liquids (ILs) have been playing important role achieving cleaner as result their excellent physicochemical properties outstanding performance dissolution fractionation lignocellulose. This review provides analysis recent advances production process biofuels from LCB using ILs highlighting techniques for optimizing costs help develop robust conversion processes.

Xylanases are hydrolytic enzymes that have tremendous applications in different sectors of life, but the high cost their production has limited use. One solution to reduce costs and enhance xylanase is use agro-wastes as a substrate fungal cultures. In this study, olive mill pomace (OMP) barley bran (BB) were used carbon sources possible inducers by three species Trichoderma (atroviride, harzianum, longibrachiatum), one major producer. The experiments conducted under solid-state fermentation system (SSF) flask cultures packed-bed bioreactor. Cultures OMP BB optimized examining ratios BB, varied particle sizes, inoculum size for Trichoderma. ratio 8:2 yielded highest activity, with 1 mm at 29 °C an × 107 spores/mL. Studying time profile process revealed activity was after seven days incubation SSF (1.779 U/mL) bioreactor (1.828 U/mL). maximum percentage degradation recorded about 15% T. harzianum cultures, compared 11% longibrachiatum Ammonium sulfate precipitation dialysis showed Xylane enzyme ranged from 0.274 U/mL 0.837 atroviride when crude extract used, (0.628 60% saturation. Xylose main sugar released all purified fractions, G-50 G-75 fractions showing units xylanase.
