Abstract The application of enzymes offers an enormous potential in the improvement existing industrial procedures and establishment new processes for obtaining high‐added value products. Enzymes provide cleaner more efficient contribute to sustainability concept. In this sense, laccases are very versatile biocatalysts currently used food, textile pulp paper sectors among others. During last years, scientific efforts have been diverted exploitation such interesting novel fields like...
Nowadays, the transport sector is one of main sources greenhouse gas (GHG) emissions and air pollution in cities. The use renewable energies therefore imperative to improve environmental sustainability this sector. In regard, biofuels play an important role as they can be blended directly with fossil fuels used traditional vehicles’ engines. Bioethanol most biofuel worldwide replace gasoline or form different gasoline-ethanol blends. Additionally, it building block obtain high added-value...
Lignin-rich residues from the cellulose-based industry are traditionally incinerated for internal energy use. The future biorefineries that convert cellulosic biomass into biofuels will generate more lignin than necessary use, and therefore value-added products could be produced. In this context, a good understanding of is prior to its valorization. present study focused on characterization lignin-rich biochemical ethanol production, including steam explosion, saccharification, fermentation,...
Although the removal of lignin and hemicelluloses from cellulose pulp to produce fully bleached nanofibrils (B-CNF) is most common practice, presence residual in raw materials for production containing (LCNFs) holds several advantages. In this work, we investigated effect Eucalyptus globulus fibers on properties resulting LCNFs. The stability colloidal suspensions was assessed by zeta-potential values charge density analyses. Morphology CNFs studied using scanning electron microscopy atomic...
This work focuses on the structural features and physicochemical properties of different Kraft lignins how they can influence electrospinning process to obtain nanostructures. Structural were characterized by nuclear magnetic resonance, size exclusion chromatography, fourier-transform infrared spectroscopy, thermal analysis, whereas chemical composition was analyzed standard method. The addition cellulose acetate (CA) improves (KL). Thus, solutions KL/CA at 30 wt% with a KL:CA weight ratio...
This work studies, for the first time, potential of a laccase from endophyte fungus Hormonema sp. CECT-13092, compared to saprophyte Trametes villosa, delignification and detoxification steam-exploded eucalypt improve subsequent bioethanol production. Regarding delignification, use T. villosa laccases did not show evidence material, rather low glucose xylose recoveries were obtained during saccharification assays laccase-treated samples with their respective controls. With regard...
This work describes the solid-state fermentation (SSF) of wheat straw with Streptomyces sp. MDG147 and further soda-pulping process to obtain soda lignins (WSLs). Subsequently, these WSLs were NCO-functionalized 1,6-hexamethylene diisocyanate then dispersed in castor oil achieve stable oleogels. The characterized using standard analytical methods, gel permeation chromatography, Fourier transform infrared spectroscopy, differential scanning calorimetry, thermogravimetric analysis. Rheological...
The usage of laccases is a sustainable and environmentally friendly approach to modifying the Kraft lignin structure for use in certain applications. However, inherent lignin, as well that resulting from laccase modification, still presents challenges fundamental comprehension successful valorization. In this study, bacterial fungal were employed modify eucalypt lignin. To evaluate type range chemical structural changes laccase-treated lignins, different NMR techniques, including solution 1H...
Abstract Pretreatment of wood or kraft pulp with endoglucanase followed by swelling in urea leaves a non-crystalline residue that can be dissolved strong aqueous sodium hydroxide-sodium borate solution. A stepwise precipitation process employing acid and barium ions separate lignin-carbohydrate complexes enriched individual polysaccharides. This procedure has been applied to eucalypt birch the corresponding pulps. Thioacidolysis various was used as major analytical technique obtain...
