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,...
The dielectric functions of Cu2ZnGeS4 bulk crystals grown by the Bridgman method were measured over energy range 1.4 to 4.7 eV at room temperature using variable angle spectroscopic ellipsometry. observed structures in adjusted Adachi’s model and attributed interband transitions E0, E1A, E1B Γ:(000), N(A):2π/a(0.5 0.5 0.5), T(Z):2π/a(0 0 0.5) points first Brillouin zone, respectively. parameters (threshold energy, strength, broadening) have been determined simulated annealing algorithm....
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...
Olive tree pruning, as one of the most abundant lignocellulosic residues in Mediterranean countries, has been evaluated a source sugars for fuel and chemicals production. A mild acid pretreatment combined with fungal using either two endophytes (Ulocladium sp. Hormonema sp.) or saprophyte (Trametes I-62). The use is based on important role that some them play during initial stages wood decomposition. Without treatment, Ulocladium provided nonsignificant enhancement 4.6% glucose...
Abstract Valorization of lignocellulosic feedstock from a Dutch elm disease tolerant Ulmus minor clone was studied as new biomass resource. Herein, fermentable sugars and activated carbons the side‐stream lignins were produced. For sugar extraction organosolv acid hydrolysis pretreatments prior to enzymatic compared for first time this hydrolysis; more efficient delignification (49 %), while at eliminating hemicelluloses (95 %). A high final glucose concentration 22–23.5 g L −1 obtained...
BACKGROUND The utility of the ascomycete Hormonema sp. CECT-13092, an endophytic fungal strain recently isolated and identified from eucalyptus tree in Spain, was investigated different biorefineries-industrial processes. used to improve enzymatic saccharification pulping Eucalyptus globulus wood; liquid culture enriched laccase activity for E. Kraft pulp biobleaching presence acetosyringone as mediator. RESULTS With regard saccharification, treatment with autohydrolysis pretreatment boosted...
The current challenges in developing a cost-effective bioethanol industry include the production of not only high-volume, low cost biofuels but also high-value products with minimal downstream waste.The up-grading side-stream lignins from plants to novel will improve profitability industry; do that, precise understanding lignin is required.In present study, ligninenriched fermentation residues (steam explosion pretreatment, saccharification, and fermentation) fastgrowing poplar forage...
Cellulose nanofibres (CNFs) can improve the quality of cardboard packaging. This work evaluates ability CNFs to impart barrier properties commercial paper used in Three were tested: mechanical (m-CNFs), by TEMPO mediated oxidation (T-CNFs) and carboxymethylated (c-CNFs). Two metering systems (wound rod blade micrometer) apply one, five 10 layers suspensions, two drying methods (hot air jet contact with a hot polished surface speed dryer) evaluated. The coated papers was measured structural...
Motivated by the negative impact of fossil fuel consumption on environment, need arises to produce materials and energy from renewable sources. Cellulose, main biopolymer Earth, plays a key role in this context, serving as platform for development biofuels, chemicals novel materials. Among latter, micro- nanocellulose have been receiving increasing attention last few years. Their many attractive properties, i.e., thermal stability, high mechanical resistance, barrier lightweight, optical...
To obtain a more realistic appraisal of the potential efficiency xylanases in industrial bleaching, influence pH and presence black liquor (measured as COD) on bleaching two commercial was studied at high temperature. These pH's, CODs, temperatures are close to those used storage tower B fiber line Jacareí unit Fibria (Brazil). The pulp samples obtained after each stage were analyzed for kappa number, brightness, viscosity, hexenuronic acid content, so effluents COD, TOC, color, turbidity,...
