• Isolation of pectin from SBP by cellulase, xylanase, and their mixtures was studied. Using mixture enzymes gave much higher yield than single enzymes. Ultrasonic pretreatment before enzymatic extraction could remarkably increase the yield. Extracted showed good oil-in-water emulsification efficiency. didn't affect Extraction sugar beet pulp using treatment ultrasonic pretreatment/enzymatic as cleaner technologies, instead acid hydrolysis Xylanase, were used for treatment. The isolated...

Abstract There has been an increasing interest in recent years isolating cellulose nanofibers from unbleached pulps for economic, environmental, and functional reasons. In the current work, isolated high-lignin neutral sulfite pulp were compared to those bleached rice straw making thin-film ultrafiltration membranes by vacuum filtration on hardened filter paper. The prepared characterized terms of their microscopic structure, hydrophilicity, pure water flux, protein fouling, ability remove...

Nanofibers isolated from unbleached neutral sulfite rice straw pulp were used to prepare transparent films without the need modify nanofibers (RSNF). RSNF with loading 1.25 10 wt.% mixed cellulose acetate (CA) solution in acetone and formed by casting. The characterized regarding their transparency light transmittance, microstructure, mechanical properties, crystallinity, water contact angle, porosity, vapor permeability, thermal properties. results showed good dispersion of CA matrix...

• Pectin was isolated from sugar beet pulp chemically and enzymatically. Both types of pectin were evaluated as corrosion inhibitor for mild steel in HCl. showed good inhibition efficiency. Enzyme-extracted had moderately higher efficiency than the acid-extracted pectin. acted mixed-type inhibitors with predominant at cathodic site. extracted using enzymatic or acid hydrolysis under acidic conditions. Effect concentration on rate studied via weight loss electrochemical measurements . The...

Abstract In this study, the effect of pectin extraction method on properties cellulose nanofibers (CNFs) isolated from sugar beet pulp (SBP) was studied. Pectin extracted by industrially practiced sulfuric acid hydrolysis or enzymatic using a cellulase/xylanase enzymes mixture. The CNFs were then high-pressure homogenization and investigated in terms their chemical composition, crystallinity, size, degree polymerization, re-dispersion water after freeze-drying. mechanical surface...

Bio-based polymer composites find increasing research and industrial interest in different areas of our life. In this study, cellulose nanofibers (CNFs) isolated from sugar beet pulp nanoemulsion prepared pectin pomegranate extract (PGE) were used for making films as coating with antioxidant antimicrobial activities paper. For Pectin/PGE preparation, ratios PGE mixed using ultrasonic treatment; the antibacterial properties evaluated to choose formula adequate activity. The activity highest...

In addition to their lower cost and more environmentally friendly nature, cellulose nanofibers isolated from unbleached pulps offer different surface properties functionality than those bleached pulps. At the same time, keep interesting such as hydrophilicity mechanical strength, close current work, rice straw (RSNF) neutral sulfite pulp (lignin content 14%) were used with polysulfone (PSF) polymer make membrane via phase inversion. The effect of RSNF on microstructure, porosity,...

Abstract Paper sludge generated from recycling of printed paper is a negative value waste since cellulosic fibers in the are too damaged to be used making and, more important, has very high content ash (up ~ 35%) and ink residues. To able utilize bio-conversion industries which depend on saccharification into sugars, de-ashing necessary. The major component fillers making, especially calcium carbonate. In current work, high-purity formate was prepared utilizing carbonate — as zero-value...

Abstract Rice straw nanofibers (RSNF) with high lignin content were used in making nanocomposites graphene oxide (GO) at loading ratios from 0.625% to 5% (based on weight of RSNF). The prepared RSNF/GO films characterized regarding their tensile strength, equilibrium moisture (EMC), and electrical properties. Microstructure the was examined using scanning electron microscopy (SEM). Addition 2.5% GO resulted increasing strength Young's modulus by 33.5% 21.5%, respectively. Presence...

Abstract Antimicrobial and UV-resistant coatings are important finishing materials for making specialty wood products. In the current work, anti-bacterial were prepared from nitrocellulose (NC) pomegranate peel extract (PGE). Different ratios of PGE added to NC solution (up 10 wt.% NC) effect on viscosity solution, optical, UV-absorption, mechanical, moisture sorption, antibacterial properties films was studied. Finally, NC/PGE with appropriate activity sprayed onto surface beechwood its...

Abstract Cellulose nanofibers isolated from unbleached pulp are characterized by different surface properties due to presence of lignin at their surface, in addition lower cost than bleached pulp. In the current work, effect cellulose neutral sulfite and soda rice straw pulps (so called UBCNF BCNF) on improving paper sheet UBP BP) was studied. The mechanical (tensile strength, burst tearing resistance) physical (porosity water vapor permeability) Scanning electron microscopy (SEM) used...
