Cellulosic nanomaterials are potential candidates in different areas, especially water treatment. In the current work, palm fruit stalks cellulose nanofibers (CNF), TEMPO-oxidized CNF (OCNF), and activated carbon (AC) were used to make thin film membranes for removal of E. coli bacteria from water. Two types layered produced: a single layer setup crosslinked two-layer AC/OCNF (bottom) (up) on hardened filter paper. The prepared evaluated regarding their microstructure layers thickness using...
• 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: Never-dried bacterial cellulose (BC) and crosslinked nanofibers (CNF) were used for the removal of oil from stabilized non-stabilized oil-in-water emulsions with droplet sizes less than 1 µm. The CNF membranes exchanged isopropyl alcohol before drying. microscopic structure prepared was evaluated using scanning electron microscopy (SEM); water flux rejection a dead-end filtration cell. BC harvested after different incubation time periods (2 to 10 days) did not show change in width...
Cellulose nanocrystals (CNC) and 2,2,6,6‐tetramethyl‐1‐piperidinyloxyl‐ (TEMPO‐) oxidized cellulose (CNC‐TEMPO) were prepared from olive stones. The characterized using transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), carboxylic groups content determination. used as reinforcing elements in chitosan nanocomposites, which X‐ray diffraction (XRD) tensile strength properties. In addition, the bioactivity of nanocomposites was studied vitro simulated body...
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...
Cell therapies offer unquestionable promises for the treatment, and in some cases even cure, of complex diseases. As we start to see more these gaining market authorization, attention is turning bioprocesses used their manufacture, particular challenge higher levels process control help regulate cell behavior, manage variability, deliver product a consistent quality. Many processes already incorporate measurement key markers such as nutrient consumption, metabolite production, concentration,...
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 Bagasse whiskers isolated from bleached bagasse pulp were chemically modified with n ‐octadecyl isocyanate in the presence of dibutyltin dilaurate as a catalyst. The cellulose used ratios 2.5 to 15% polycaprolactone (PCL) polymer prepare nanocomposite films by solution/casting technique. prepared nanocomposites characterized regard their biodegradability soil and moisture‐barrier, moisture sorption, mechanical, thermal, thermomechanical properties. use resulted improvements...
Aims: Studying the biological activities of A. xylinum ATCC 10245 (as reference strain) and K. saccharivorans PE5 for bacterial cellulose production (B.C) under optimized fermentation conditions structural characteristics produced.Study Design: The optimal by investigated strains then purified was characterized different techniques.
