Cellulose is one of the most frequently used natural polymers. Some characteristics Carboxymethyl cellulose polymer have been studied, which a semi-crystalline, non-toxic material. CMC made by several methods including homogeneous Procedures and heterogeneous Procedures. It also has many applications such as its use in Pharmaceuticals Cosmetics, Drilling Fluids, Manufacture, CMC-Based Drug Deli...

Bacterial cellulose (BC) is a suitable material for biomedical applications due to its remarkable proprieties, such us: biodegradability, biocompatibility and ready availability. In this paper the swelling and drug release profiles from bacterial cellulosecarboxymethyl cellulose (BC-CMC) composite hydrogels were investigated, in the aim to use such systems in controlled drug delivery field. Ibu...

The gram-positive spore-forming bacteria, Bacillus thuringiensis (Bt) strains produced novel cellulases which could liberate glucose from soluble cellulose, carboxymethyl cellulose (CMC), and insoluble crystalline cellulose. The maximal cellulase activities were obtained after 60 hrs incubation at 28oC in a LB broth medium with 1% CMC. Maximum CMCase activities were got at 40oC and pH 4.0, resp...

Polyvinyl alcohol (PVA) / starch (S) /Carboxy methyl cellulose (CMC) composite films were prepared from PVA, three different loading of CMC and soluble starch aqueous suspensions by casting method in the presence of plasticize containing glycerol. The effects of the CMC addition on the some physical properties of the resulted blend films were investigated. Tensile tests demonstrated positive re...

Cellulose nanofibrils (CNF) were produced by high-pressure homogenization from kraft pulp in the presence of carboxymethyl cellulose (CMC) varying molecular weights. CNF pretreated with 250 kD CMC exhibited maximum specific surface area (SSA) 641 m2/g, which is comparable to that 2,2,6,6-tetramethyl-piperidinyl-1-oxyl (TEMPO)-meditated oxidation a high degree fibrillation. Rheological and micro...

In this work, cellulose was successfully extracted from pineapple leaf waste by 0.75 M NaOH at 90oC and 5 HNO3 70oC for 1.5 h h, respectively. The obtained fibres, with average diameters of 150-300 nm, were converted to carboxymethyl (CMC) esterification. pure soaked in a solution mixture isopropanol 2 h. It then reacted chloroacetic acid (MCA) 60oC optimum conditions carboxymethylation found b...

The design of novel binder systems is required for the high capacity silicon (Si) anodes which usually undergo huge volume change during the charge/discharge cycling. Here, we introduce a poly (acrylic acid sodium)-grafted-carboxymethyl cellulose (NaPAA-g-CMC) copolymer as an excellent binder for Si anode in lithium ion batteries (LIBs). The NaPAA-g-CMC copolymer was prepared via a free radical...

A cellulase producing bacterium (E3 strain) was isolated from fecal matter of elephant and identified as Bacillus sp. using 16S rDNA sequenced based molecular phylogenetic approach. While studying the effect of substrates like Carboxymethyl cellulose (CMC), avicel, starch, maltose, sucrose, glucose, fructose, galactose and lactose on cellulase production, it was found that CMC was best carbon s...

A carboxymethyl cellulase gene, cel5B, was cloned, sequenced, and expressed in Escherichia coli. pRCS20 in E. coli was identified from metagenomic cosmid library of cow rumen for cellulase activity on a carboxymethyl cellulose agar plates. Cosmid clone (RCS20) was partially digested with Sau3AI, ligated into BamHI site of pBluescript II SK+ vector, and transformed into E. coli DH5α. The insert ...

Microbial fuel cells (MFCs) convert biodegradable materials into electricity, potentially contributing to an array of renewable energy production strategies tailored for specific applications. Since there are no known microorganisms that can both metabolize cellulose and transfer electrons to solid extracellular substrates, the conversion of cellulosic biomass to electricity requires a syntroph...
