The effect of adsorbed and soluble carboxymethyl cellulose (CMC) on dispersing, dewaterability, and fines retention of pulp fibre suspensions was investigated. CMC was added to a suspension in the presence of electrolytes, causing its adsorption to the fibre surfaces, or to a suspension without electrolytes, so that it stayed in the liquid phase. Both the CMC adsorbed on fibre surfaces and that...

Background: Edible films and coatings are biodegradable that can preserve the quality and extend the shelf life of foods. The aim of this study was to investigate the physical and mechanical properties, and antimicrobial activity of carboxymethyl cellulose (CMC) film containing Artemisia sieberi Essential Oil (AEO). Methods: The studied parameters were the antibacterial activity and physical p...

This study aimed to develop an environmentally friendly silver nanoparticles (AgNPs) using banana peel extract as reducing and capping agent. AgNPs obtained were characterized via Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM). Preservation of blocks coated with sodium carboxymethyl cellulose (Na-CMC) Na-CMC incorporated (Na-CMC + AgNPs) for 5 days also condu...

Direct ethanol fermentation from amorphous cellulose was achieved using an engineered industrial Saccharomyces cerevisiae strain. Two cellulase genes endoglucanase (eg3) and β-glucosidase (bgl1) were obtained from Trichoderma viride and integrated into the genome of S. cerevisiae. These two cellulases could be constitutively coexpressed and secreted by the recombinant strain S. cerevisiae-eb. T...

The present study was conducted to develop a nanocomposite film of carboxymethyl cellulose (CMC) reinforced with nanocrystals isolated from microcrystalline (CNCMCC) in the presence bismuth ferrite (BFO)/poly-o-phenylenediamine (PoPD). physicochemical properties, mechanical and thermal stability, its photocatalytic activity towards removal methyl orange (MO) were determined. Results show that i...

drying foodstuffs can have negative effects on quantitative and qualitative characteristics of the products, including porosity and bulk density. therefore, novel technologies can be used to improve these characteristics. in this study, apparent density changes during drying grapes pretreated with ultrasound for 10, 20 and 30 minutes, and carboxymethyl cellulose (cmc) at three concentrations of...

Alum had been used in traditional medicine for treatment of oral lesions in Iran.the main aim of this study was to find out a suitable formulation for the mucoadhesive fprm of alum.in this study some materials such as alum,carboxymethyl cellulose  (CMC) and Arabic Gum were used.different bases of gum and CMC were made and titration of alum was performed with suitable vbuffer and the rate of wa...
