This paper applied a simple and cost-benefit method for the production of regenerated bacterial cellulose. The inexpensive production of cellulose with complex media derived from wastewater from food industries such as molasses adds a lot of contaminants to the produced bacterial cellulose, which puts a lot of challenges in cellulose purification. Therefore, the present study aimed...

The cellulose derivative hydroxypropyl methylcellulose (HPMC) has recently been extensively studied and used in mechanical applications. However, the softness susceptibility to deformation of HPMC limited its further In this study, metal nanoparticles (nano-aluminum nano-copper) nano-metal oxide particles (nano-alumina nano-copper oxide) were as additives form a composite film with improved pro...

Reduced graphene oxide/poly (ionic liquid) functionalized nano-fibrillated cellulose composite paper with significant enhancement of mechanical strength, ductility, toughness and hydrophobicity was fabricated by vacuum filtration assisted assembly.

Drug-loaded mono- and multilayer composite membranes were prepared. The composites, based on nano-fibrillated bacterial cellulose, nano-powdered polyvinyl alcohol, all biocompatible biodegradable, characterized in terms of basic factors related to drug diffusivity mass transfer: swelling ability, water solubility, vapor permeability. Tetracycline hydrochloride was used this case as model. Drug ...

BACKGROUND The efficiency of enzymatic hydrolysis is reduced by the structural properties of cellulose. Although efforts have been made to explain the mechanism of enzymatic hydrolysis of cellulose by considering the interaction of cellulolytic enzymes with cellulose or the changes in the structure of cellulose during enzymatic hydrolysis, the process of cellulose hydrolysis is not yet fully un...

Cellulose hydrogels are extensively applied in many biotechnological fields and are also used as models for plant cell walls. We synthesised model cellulosic hydrogels containing hemicelluloses, as a biomimetic of plant cell walls, in order to study the role of hemicelluloses on their mass transport properties. Microbial cellulose is able to self-assemble into composites when hemicelluloses, su...

This study demonstrated the potential of simultaneously recovering cellulosic solid residues (CSR) and producing cellulose nanocrystals (CNCs) by strong sulfuric acid hydrolysis to minimize cellulose loss to near zero. A set of slightly milder acid hydrolysis conditions than that considered as "optimal" were used to significantly minimize the degradation of cellulose into soluble sugars that ca...

Chemical functionalization of cellulose aims to adjust the properties of macromolecule for different purposes, particularly, as a chemical feedstock for production of cellulose derivatives for a variety of applications. The conventional sources of cellulose include cotton linters and wood pulp which now-a-days are discouraged on account of the cost of the former and environment conservative reg...
