Biopolymer nanoparticles can be formed by heating globular protein/polysaccharide mixtures above the thermal denaturation temperature of the protein under pH conditions where the two biopolymers are weakly electrically attracted to each other. In this study, the influence of polysaccharide linear charge density on the formation and properties of these biopolymer nanoparticles was examined. Mixe...

Lignin is the second most abundant biopolymer after cellulose. It has long been obtained as a by-product of cellulose production in pulp and paper production, but had rather low added-value applications. A changing paper market and the emergence of biorefinery projects should generate vast amounts of lignin with the potential of value addition. Nanomaterials offer unique properties and the prep...

Chloride-induced corrosion of steel reinforcement is a major factor adversely influencing the durability of reinforced concrete structures. The main objective of this preliminary study was to explore the use of waste residues generated during the bioethanol processing of sugar cane bagasse as a source of high value products, primarily lignin that can be functionalized to scavenge chloride ions ...

The intermolecular interactions involved in oligosaccharide-protein recognition, binding and cleavage are complex. Elucidation of these complex interactions is important in order to understand the biochemical role these proteins play. Fluorescence spectroscopy is a very good method to study the binding between a substrate and receptor. A non-native form (E315L) of the Family 18 Chitinase from t...

Cellulose is a central component in plant cell walls. In the primary cell wall (deposited in cells that are still expanding), it is a vital component of the load-bearing network and because of its physical properties is important in determining the orientation of cell expansion. After a period of cell expansion, some cells lay down a thick secondary cell wall inside the primary wall. The second...

With the depletion of fossil resources and ever-increasing energy demand, it becomes crucial to address global challenge sustainable routes renewable dielectric materials, which can store electrostatically for flexible electronics pulsed power applications. Here, TEMPO-oxidized cellulose nanofibrils with tailored charge density are synthesized mixed colloidal poly(vinylidene fluoride) nanoparti...

Biopolymers represent a great resource for the development and utilization of new functional materials due to their particular advantages such as biocompatibility, biodegradability non-toxicity. “Intelligent gels” sensitive different stimuli (temperature, pH, ionic strength) have applications in many industries (e.g., pharmacy, biomedicine, food). This review summarizes research efforts present...

Cellulose is the utmost plenteous source of biopolymer in our earth, and fungi are most efficient ubiquitous organism degrading cellulosic biomass by synthesizing cellulases. Tailoring through genetic manipulation has played a substantial role constructing novel fungal strains towards improved cellulase production desired traits. However, traditional methods time-consuming tedious. With availab...

The construction industry remains a significant contributor to global carbon emissions. Several sustainable alternatives have emerged overcome this issue in geotechnical engineering. In study, cellulose, an abundant biopolymer, is investigated for its potential modify properties favourably. Sodium carboxymethyl cellulose (NaCMC) anionic ether derivative of natural with good binding and moisture...

This study describes the preparation of a novel proton conducting membranes based on bacterial cellulose (BC) modified by grafting of 2-acrylamido-2-methyl-1 -propanesulfonic acid (AMPS) through UV-induced graft polymerization. These AMPS-g-BC membranes have been characterized by various techniques including FTIR, SEM and TGA, to find their successful grafting of AMPS on BC, surface morphology ...
